元注解:
元注解的作用就是負(fù)責(zé)注解其他注解。Java5.0定義了4個(gè)標(biāo)準(zhǔn)的meta-annotation類型,它們被用來提供對(duì)其它 annotation類型作說明。Java5.0定義的元注解:
1.@Target,
2.@Retention,
3.@Documented,
4.@Inherited
以下為一個(gè)簡單場(chǎng)景的應(yīng)用:
1.定義注解:
@Target(TYPE)
@Retention(RUNTIME)
public @interface Table {
/**
* (Optional) The name of the table.
* <p/>
* Defaults to the entity name.
*/
String name() default "";
}
@Target({METHOD, FIELD})2、定義實(shí)體類:
@Retention(RUNTIME)
public @interface Column {
/**
* (Optional) The name of the column. Defaults to
* the property or field name.
*/
String name() default "";
}
@Table(name = "t_s_user")
public class User {
@Column(name="name")
private String name;
@Column(name="pwd")
private String pwd;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPwd() {
return pwd;
}
public void setPwd(String pwd) {
this.pwd = pwd;
}
}
3、運(yùn)行:
public static void print() {
System.out.println("table's name:" + User.class.getAnnotation(Table.class).name());
Field[] fields = User.class.getDeclaredFields();
for (int i = 0; i < fields.length; i++) {
Field field = fields[i];
System.out.println("field's type:" + field.getType().getName());
System.out.println("field's columnName:" + field.getAnnotation(Column.class).name());
}
}
關(guān)于注解的詳細(xì)介紹:http://www.cnblogs.com/peida/archive/2013/04/24/3036689.html
2.左上角選擇添加,選擇添加java(還提供了添加maven項(xiàng)目),然后選擇所需要的目錄:
3.idea 會(huì)提示選擇添加什么類型的文件,我們是單純的文件,所以選擇classes

return application.sources(Application.class);
}
修改packaging

Spring Data JDBC generic DAO implementation
The purpose of this project is to provide generic, lightweight and easy to use DAO implementation for relational databases based on JdbcTemplate
from Spring framework, compatible with Spring Data umbrella of projects.
Design objectives
- Lightweight, fast and low-overhead. Only a handful of classes, no XML, annotations, reflection
- This is not full-blown ORM. No relationship handling, lazy loading, dirty checking, caching
- CRUD implemented in seconds
- For small applications where JPA is an overkill
- Use when simplicity is needed or when future migration e.g. to JPA is considered
- Minimalistic support for database dialect differences (e.g. transparent paging of results)
Features
Each DAO provides built-in support for:
- Mapping to/from domain objects through
RowMapper
abstraction - Generated and user-defined primary keys
- Extracting generated key
- Compound (multi-column) primary keys
- Immutable domain objects
- Paging (requesting subset of results)
- Sorting over several columns (database agnostic)
- Optional support for many-to-one relationships
- Supported databases (continuously tested):
- MySQL
- PostgreSQL
- H2
- HSQLDB
- Derby
- MS SQL Server (2008, 2012)
- Oracle 10g / 11g (9i should work too)
- ...and most likely many others
- Easily extendable to other database dialects via
SqlGenerator
class. - Easy retrieval of records by ID
API
Compatible with Spring Data PagingAndSortingRepository
abstraction, all these methods are implemented for you:
public interface PagingAndSortingRepository<T, ID extends Serializable> extends CrudRepository<T, ID> {
T save(T entity);
Iterable<T> save(Iterable<? extends T> entities);
T findOne(ID id);
boolean exists(ID id);
Iterable<T> findAll();
long count();
void delete(ID id);
void delete(T entity);
void delete(Iterable<? extends T> entities);
void deleteAll();
Iterable<T> findAll(Sort sort);
Page<T> findAll(Pageable pageable);
Iterable<T> findAll(Iterable<ID> ids);
}
Pageable
and Sort
parameters are also fully supported, which means you get paging and sorting by arbitrary properties for free. For example say you have userRepository
extending PagingAndSortingRepository<User, String>
interface (implemented for you by the library) and you request 5th page of USERS
table, 10 per page, after applying some sorting:
Page<User> page = userRepository.findAll(
new PageRequest(
5, 10,
new Sort(
new Order(DESC, "reputation"),
new Order(ASC, "user_name")
)
)
);
Spring Data JDBC repository library will translate this call into (PostgreSQL syntax):
SELECT *
FROM USERS
ORDER BY reputation DESC, user_name ASC
LIMIT 50 OFFSET 10
...or even (Derby syntax):
SELECT * FROM (
SELECT ROW_NUMBER() OVER () AS ROW_NUM, t.*
FROM (
SELECT *
FROM USERS
ORDER BY reputation DESC, user_name ASC
) AS t
) AS a
WHERE ROW_NUM BETWEEN 51 AND 60
No matter which database you use, you'll get Page<User>
object in return (you still have to provide RowMapper<User>
yourself to translate from ResultSet
to domain object). If you don't know Spring Data project yet, Page<T>
is a wonderful abstraction, not only encapsulating List<T>
, but also providing metadata such as total number of records, on which page we currently are, etc.
Reasons to use
-
You consider migration to JPA or even some NoSQL database in the future.
Since your code will rely only on methods defined in
PagingAndSortingRepository
andCrudRepository
from Spring Data Commons umbrella project you are free to switch fromJdbcRepository
implementation (from this project) to:JpaRepository
,MongoRepository
,GemfireRepository
orGraphRepository
. They all implement the same common API. Of course don't expect that switching from JDBC to JPA or MongoDB will be as simple as switching imported JAR dependencies - but at least you minimize the impact by using same DAO API. -
You need a fast, simple JDBC wrapper library. JPA or even MyBatis is an overkill
-
You want to have full control over generated SQL if needed
-
You want to work with objects, but don't need lazy loading, relationship handling, multi-level caching, dirty checking... You need CRUD and not much more
-
You want to by DRY
-
You are already using Spring or maybe even
JdbcTemplate
, but still feel like there is too much manual work -
You have very few database tables
Getting started
For more examples and working code don't forget to examine project tests.
Prerequisites
Maven coordinates:
<dependency>
<groupId>com.nurkiewicz.jdbcrepository</groupId>
<artifactId>jdbcrepository</artifactId>
<version>0.4</version>
</dependency>
This project is available under maven central repository.
Alternatively you can download source code as ZIP.
In order to start your project must have DataSource
bean present and transaction management enabled. Here is a minimal MySQL configuration:
@EnableTransactionManagement
@Configuration
public class MinimalConfig {
@Bean
public PlatformTransactionManager transactionManager() {
return new DataSourceTransactionManager(dataSource());
}
@Bean
public DataSource dataSource() {
MysqlConnectionPoolDataSource ds = new MysqlConnectionPoolDataSource();
ds.setUser("user");
ds.setPassword("secret");
ds.setDatabaseName("db_name");
return ds;
}
}
Entity with auto-generated key
Say you have a following database table with auto-generated key (MySQL syntax):
CREATE TABLE COMMENTS (
id INT AUTO_INCREMENT,
user_name varchar(256),
contents varchar(1000),
created_time TIMESTAMP NOT NULL,
PRIMARY KEY (id)
);
First you need to create domain object User
mapping to that table (just like in any other ORM):
public class Comment implements Persistable<Integer> {
private Integer id;
private String userName;
private String contents;
private Date createdTime;
@Override
public Integer getId() {
return id;
}
@Override
public boolean isNew() {
return id == null;
}
//getters/setters/constructors/...
}
Apart from standard Java boilerplate you should notice implementing Persistable<Integer>
where Integer
is the type of primary key. Persistable<T>
is an interface coming from Spring Data project and it's the only requirement we place on your domain object.
Finally we are ready to create our CommentRepository
DAO:
@Repository
public class CommentRepository extends JdbcRepository<Comment, Integer> {
public CommentRepository() {
super(ROW_MAPPER, ROW_UNMAPPER, "COMMENTS");
}
public static final RowMapper<Comment> ROW_MAPPER = //see below
private static final RowUnmapper<Comment> ROW_UNMAPPER = //see below
@Override
protected <S extends Comment> S postCreate(S entity, Number generatedId) {
entity.setId(generatedId.intValue());
return entity;
}
}
First of all we use @Repository
annotation to mark DAO bean. It enables persistence exception translation. Also such annotated beans are discovered by CLASSPATH scanning.
As you can see we extend JdbcRepository<Comment, Integer>
which is the central class of this library, providing implementations of all PagingAndSortingRepository
methods. Its constructor has three required dependencies: RowMapper
, RowUnmapper
and table name. You may also provide ID column name, otherwise default "id"
is used.
If you ever used JdbcTemplate
from Spring, you should be familiar with RowMapper
interface. We need to somehow extract columns from ResultSet
into an object. After all we don't want to work with raw JDBC results. It's quite straightforward:
public static final RowMapper<Comment> ROW_MAPPER = new RowMapper<Comment>() {
@Override
public Comment mapRow(ResultSet rs, int rowNum) throws SQLException {
return new Comment(
rs.getInt("id"),
rs.getString("user_name"),
rs.getString("contents"),
rs.getTimestamp("created_time")
);
}
};
RowUnmapper
comes from this library and it's essentially the opposite of RowMapper
: takes an object and turns it into a Map
. This map is later used by the library to construct SQL CREATE
/UPDATE
queries:
private static final RowUnmapper<Comment> ROW_UNMAPPER = new RowUnmapper<Comment>() {
@Override
public Map<String, Object> mapColumns(Comment comment) {
Map<String, Object> mapping = new LinkedHashMap<String, Object>();
mapping.put("id", comment.getId());
mapping.put("user_name", comment.getUserName());
mapping.put("contents", comment.getContents());
mapping.put("created_time", new java.sql.Timestamp(comment.getCreatedTime().getTime()));
return mapping;
}
};
If you never update your database table (just reading some reference data inserted elsewhere) you may skip RowUnmapper
parameter or use MissingRowUnmapper
.
Last piece of the puzzle is the postCreate()
callback method which is called after an object was inserted. You can use it to retrieve generated primary key and update your domain object (or return new one if your domain objects are immutable). If you don't need it, just don't override postCreate()
.
Check out JdbcRepositoryGeneratedKeyTest
for a working code based on this example.
By now you might have a feeling that, compared to JPA or Hibernate, there is quite a lot of manual work. However various JPA implementations and other ORM frameworks are notoriously known for introducing significant overhead and manifesting some learning curve. This tiny library intentionally leaves some responsibilities to the user in order to avoid complex mappings, reflection, annotations... all the implicitness that is not always desired.
This project is not intending to replace mature and stable ORM frameworks. Instead it tries to fill in a niche between raw JDBC and ORM where simplicity and low overhead are key features.
Entity with manually assigned key
In this example we'll see how entities with user-defined primary keys are handled. Let's start from database model:
CREATE TABLE USERS (
user_name varchar(255),
date_of_birth TIMESTAMP NOT NULL,
enabled BIT(1) NOT NULL,
PRIMARY KEY (user_name)
);
...and User
domain model:
public class User implements Persistable<String> {
private transient boolean persisted;
private String userName;
private Date dateOfBirth;
private boolean enabled;
@Override
public String getId() {
return userName;
}
@Override
public boolean isNew() {
return !persisted;
}
public void setPersisted(boolean persisted) {
this.persisted = persisted;
}
//getters/setters/constructors/...
}
Notice that special persisted
transient flag was added. Contract of [CrudRepository.save()
](http://static.springsource.org/spring-data/data-commons/docs/current/api/org/springframework/data/repository/CrudRepository.html#save(S)) from Spring Data project requires that an entity knows whether it was already saved or not (isNew()
) method - there are no separate create()
and update()
methods. Implementing isNew()
is simple for auto-generated keys (see Comment
above) but in this case we need an extra transient field. If you hate this workaround and you only insert data and never update, you'll get away with return true
all the time from isNew()
.
And finally our DAO, UserRepository
bean:
@Repository
public class UserRepository extends JdbcRepository<User, String> {
public UserRepository() {
super(ROW_MAPPER, ROW_UNMAPPER, "USERS", "user_name");
}
public static final RowMapper<User> ROW_MAPPER = //...
public static final RowUnmapper<User> ROW_UNMAPPER = //...
@Override
protected <S extends User> S postUpdate(S entity) {
entity.setPersisted(true);
return entity;
}
@Override
protected <S extends User> S postCreate(S entity, Number generatedId) {
entity.setPersisted(true);
return entity;
}
}
"USERS"
and "user_name"
parameters designate table name and primary key column name. I'll leave the details of mapper and unmapper (see source code). But please notice postUpdate()
and postCreate()
methods. They ensure that once object was persisted, persisted
flag is set so that subsequent calls to save()
will update existing entity rather than trying to reinsert it.
Check out JdbcRepositoryManualKeyTest
for a working code based on this example.
Compound primary key
We also support compound primary keys (primary keys consisting of several columns). Take this table as an example:
CREATE TABLE BOARDING_PASS (
flight_no VARCHAR(8) NOT NULL,
seq_no INT NOT NULL,
passenger VARCHAR(1000),
seat CHAR(3),
PRIMARY KEY (flight_no, seq_no)
);
I would like you to notice the type of primary key in Persistable<T>
:
public class BoardingPass implements Persistable<Object[]> {
private transient boolean persisted;
private String flightNo;
private int seqNo;
private String passenger;
private String seat;
@Override
public Object[] getId() {
return pk(flightNo, seqNo);
}
@Override
public boolean isNew() {
return !persisted;
}
//getters/setters/constructors/...
}
Unfortunately library does not support small, immutable value classes encapsulating all ID values in one object (like JPA does with @IdClass
), so you have to live with Object[]
array. Defining DAO class is similar to what we've already seen:
public class BoardingPassRepository extends JdbcRepository<BoardingPass, Object[]> {
public BoardingPassRepository() {
this("BOARDING_PASS");
}
public BoardingPassRepository(String tableName) {
super(MAPPER, UNMAPPER, new TableDescription(tableName, null, "flight_no", "seq_no")
);
}
public static final RowMapper<BoardingPass> ROW_MAPPER = //...
public static final RowUnmapper<BoardingPass> UNMAPPER = //...
}
Two things to notice: we extend JdbcRepository<BoardingPass, Object[]>
and we provide two ID column names just as expected: "flight_no", "seq_no"
. We query such DAO by providing both flight_no
and seq_no
(necessarily in that order) values wrapped by Object[]
:
BoardingPass pass = boardingPassRepository.findOne(new Object[] {"FOO-1022", 42});
No doubts, this is cumbersome in practice, so we provide tiny helper method which you can statically import:
import static com.nurkiewicz.jdbcrepository.JdbcRepository.pk;
//...
BoardingPass foundFlight = boardingPassRepository.findOne(pk("FOO-1022", 42));
Check out JdbcRepositoryCompoundPkTest
for a working code based on this example.
Transactions
This library is completely orthogonal to transaction management. Every method of each repository requires running transaction and it's up to you to set it up. Typically you would place @Transactional
on service layer (calling DAO beans). I don't recommend placing @Transactional
over every DAO bean.
Caching
Spring Data JDBC repository library is not providing any caching abstraction or support. However adding @Cacheable
layer on top of your DAOs or services using caching abstraction in Spring is quite straightforward. See also: @Cacheable overhead in Spring.
Contributions
..are always welcome. Don't hesitate to submit bug reports and pull requests.
Testing
This library is continuously tested using Travis (). Test suite consists of 60+ distinct tests each run against 8 different databases: MySQL, PostgreSQL, H2, HSQLDB and Derby + MS SQL Server and Oracle tests not run as part of CI.
When filling bug reports or submitting new features please try including supporting test cases. Each pull request is automatically tested on a separate branch.
Building
After forking the official repository building is as simple as running:
$ mvn install
You'll notice plenty of exceptions during JUnit test execution. This is normal. Some of the tests run against MySQL and PostgreSQL available only on Travis CI server. When these database servers are unavailable, whole test is simply skipped:
Results :
Tests run: 484, Failures: 0, Errors: 0, Skipped: 295
Exception stack traces come from root AbstractIntegrationTest
.
Design
Library consists of only a handful of classes, highlighted in the diagram below (source):
JdbcRepository
is the most important class that implements all PagingAndSortingRepository
methods. Each user repository has to extend this class. Also each such repository must at least implement RowMapper
and RowUnmapper
(only if you want to modify table data).
SQL generation is delegated to SqlGenerator
. PostgreSqlGenerator.
and DerbySqlGenerator
are provided for databases that don't work with standard generator.

現(xiàn)階段JAVA操作Excel的JAR主要有apache 的POI及jxl.Jxl方便快捷,POI用于對(duì)復(fù)雜Excel的操作。
Jxl官網(wǎng):http://www.andykhan.com/jexcelapi/index.html
一、Jxl的API
Jxl的API主要有三個(gè)包,jxl,jxl.format,jxl.write。如果單獨(dú)的分析API,可能對(duì)于更明確的了解此API沒有太多的幫助,我們還是從Excel文件的層次來剝離此API吧。
一個(gè)excel文件由一個(gè)工作簿組成,一個(gè)工作簿又由n個(gè)工作表組成,每個(gè)工作表又由多個(gè)單元格組成。對(duì)應(yīng)于Jxl中的結(jié)構(gòu)為
讀文件(包jxl) | 寫文件(包jxl.write) | 說明 |
Workbook | WritableWorkbook | 工作簿 |
Sheet | WritableSheet | 工作表 |
Cell/Image/Hyperlink | WritableCell/WritableImage//WritableHyperlink | 單元格/圖像/超鏈接 |
單元格(此處指文本單元格,圖像及鏈接和單元格做為一個(gè)層次)分為好多種,所以在API的設(shè)計(jì)中將Cell作為一個(gè)接口而存在。 對(duì)應(yīng)的jxl中的結(jié)構(gòu)為:
讀文件(包jxl) | 寫文件(包jxl.write) | 說明 |
Cell | WritableCell | 單元格 |
BooleanCell | Boolean | 布爾值單元格 |
DateCell | DateTime | 時(shí)間單元格 |
ErrorCell |
| 形式錯(cuò)誤的單元格 |
LabelCell | Label | 文本單元格 |
NumberCell | Number | 數(shù)字單元格 |
FormualCedll | Formual | 公式單元格 |
| Blank | 空格單元格 |
BooleanFormualCell |
| 布爾公式單元格 |
DateFormualCell |
| 時(shí)間公式單元格 |
ErrorFormualCell |
| 錯(cuò)誤公式單元格 |
StringFormualCell |
| 文本公式單元格 |
NumberFormualCell |
| 數(shù)字公式單元格 |
而有的時(shí)候,我們可能將幾個(gè)單元格作為一個(gè)整體來處理,在API中對(duì)應(yīng)的則是:
jxl.Range
雖然數(shù)據(jù)是電子表格的核心,但是同時(shí)其也需要一些輔助類,比如文件格式設(shè)置,工作表設(shè)置與顯示效果,單元格設(shè)置與顯示效果等。按照其層次,則依次有以下接口或類。
讀文件(包jxl) | 寫文件(包jxl.write) | 說明 |
WorkbookSettings | WorkbookSettings(包jxl) | 設(shè)置workbook屬性的bean |
SheetSettings | SheetSettings(包jxl) | 設(shè)置具體sheet的屬性的bean(比如表頭表底等) |
HeaderFooter | HeaderFooter(包jxl) | 表示表頭表底類 |
HeaderFooter.Contents | HeaderFooter.Contents(包jxl) | 具體表頭表底設(shè)置 |
CellFeatures | WritableCellFeautres | 表格內(nèi)容相關(guān)設(shè)置(驗(yàn)證) |
CellReferenceHelper |

myeclipse中的字體看上去比較舒服,但是忽然使用eclipse找不到該字體。具體介紹及解決辦法如下:
myeclipse用Courier New這個(gè)字體,但是這個(gè)字體在Eclipse中默認(rèn)是選不出來的。到Eclipse preference--->colors and fonts中 找到選擇字體的地方(選擇字體的下拉菜單中是找不到Courier New的),在左下方有一行藍(lán)色的字“顯示更多字體”,點(diǎn)擊后會(huì)出現(xiàn)一個(gè)新的界面,這里會(huì)顯示你機(jī)器上所有的字體。找到Courier New后點(diǎn)擊右鍵選擇[顯示],然后關(guān)閉這個(gè)界面?;氐礁淖煮w的界面后你會(huì)發(fā)現(xiàn)下拉菜單中已經(jīng)可以選擇Courier New這個(gè)字體了。然后將該字體默認(rèn)即可!

人們常說程序員的生活枯燥為人刻板,其實(shí)這是你不懂程序員,代碼之外,這些高智商的人幽默有趣,論壇常常是他們展現(xiàn)才華的地方,BLOG是他們分享技術(shù)的地方,BBS等地方有問題他門總是熱心幫助解答,處理程序異常,修改程序錯(cuò)誤等。
程序員也是很懂得品味人生的,因?yàn)楣ぷ饔绊懰T也許會(huì)對(duì)生活感慨,傷感自己沒足夠或是更多的時(shí)間去做工作之外的別的事。陪朋友,親戚,家人、甚至陪女朋友去買套漂亮的衣服的時(shí)間都沒有等。但是我個(gè)人意見認(rèn)為,程序員是最誠實(shí)、最實(shí)用主義及最愛恨分明的,平日工作雖然單調(diào)但不乏味。
程序員是最誠實(shí)從何談起?
程序員在學(xué)習(xí)和工作期間幾乎天天和機(jī)器打交道,壓根就沒有受欺負(fù)或是欺負(fù)別人的機(jī)會(huì),勤奮的程序員在調(diào)試無窮多的程序BUG時(shí),已經(jīng)深深地接受了“誠實(shí)”的教育,不誠實(shí)的人,他肯定不想做、也做不好程序員。
為何說程序員是最實(shí)用主義?
在10年前我第一次聽說電腦,后來初中文化課程中也開設(shè)了叫《計(jì)算機(jī)信息技術(shù)》這么一門課程,當(dāng)時(shí)老師不停的在講臺(tái)上給我們講計(jì)算機(jī)是如何的厲害,但他在我門心里一直只是個(gè)神話傳說,上一年的計(jì)算機(jī)課還沒曾見過真正的計(jì)算機(jī)的廬山真面目,只是從老師的口中聽說過他是如何的神。從我聽說計(jì)算機(jī)到后來我學(xué)習(xí)計(jì)算機(jī)甚至是現(xiàn)在我從事的計(jì)算機(jī)的工作,已經(jīng)過去了10個(gè)春夏秋冬了,但是目前最先進(jìn)的計(jì)算機(jī)也不具備智能,他其實(shí)是笨的他也需要人員去操作,當(dāng)我成為程序員的那刻我意識(shí)到計(jì)算機(jī)的神話是眾多程序員的汗水堆積起來的。
程序員如何的愛恨分明?
程序員大都喜歡技術(shù)挑戰(zhàn),不喜歡搞測(cè)試與維護(hù)。高水平的程序員喜歡和高水平的程序員一起工作,我也是這樣的一個(gè)人,我怕“與臭棋佬下棋,棋越下越臭”。
也許是因?yàn)楣ぷ饔绊懀蓍e太少吧,程序員大都不喜歡拉幫結(jié)派、耍政治手腕。不信,你數(shù)數(shù)你認(rèn)識(shí)的程序員,有幾個(gè)人黨派人士?又有幾個(gè)是政府官員?說到這里我想到了窮人,因?yàn)槲乙彩歉F人之一。窮人為什么總是窮,很難變?yōu)楦辉5娜四兀恳驗(yàn)楦F人怕,怕付出沒回報(bào),怕投資得不到利益。怕高官怕大人物以至于不趕去和異類人群接觸,始終活動(dòng)在窮人堆里,又怎么會(huì)變得富裕呢?出非出現(xiàn)奇跡,麻雀巢里飛出個(gè)金鳳凰。呵呵,說遠(yuǎn)了。
何解工作單調(diào)卻不乏味?
程序設(shè)計(jì)的真正含義是什么?
要塑造一個(gè)程序員又需要多少時(shí)間和經(jīng)歷呢?又有那些過程呢?學(xué)習(xí)過程的天空是黑暗的,記得以前在大學(xué)的時(shí)候,每天起床后的第一件事就是打開電腦,然后洗溯吃飯,接著就是看書寫代碼這些,餓了又去吃飯然后又面對(duì)電腦,當(dāng)困了的時(shí)候就倒下睡覺。醒了又爬起來,很少和朋友家人聯(lián)系,每天都過著這樣的單調(diào)的循環(huán)生活,但很遺憾的是我和電腦這么的親密接觸到現(xiàn)在還是不能達(dá)到人機(jī)合一的境界。
我記得我曾經(jīng)說過,我最好的朋友是我的電腦,無論我是高興還是煩惱,無論我是興奮還是疲倦,一直陪伴著我的始終是他。但這句話是針對(duì)不同的時(shí)間到,如果參加工作了,或許工作中的任務(wù)、同事之間的友誼、個(gè)人生活中的感情等等都將會(huì)成為我們的最愛。總的來說是因事而異、因人而異。
餓了就吃,困了就睡,只要時(shí)機(jī)恰當(dāng)就進(jìn)行程序設(shè)計(jì)。生活、學(xué)習(xí)及工作融為一體,盡管單調(diào)卻不乏味,還能獨(dú)享孤獨(dú)。

80、某男是程序員,每天半夜三更才回家。某女抱怨:“你就不能提早點(diǎn)回家么?” 某男:“好,一定。” 于是下次某男一直寫代碼到天亮提著油條豆?jié){才回家。
81、有人說,女程序員再淑女,一旦編程就會(huì)暴露自己的身份,習(xí)慣性的把前額的頭發(fā)往上捋,露出大大的額頭。因?yàn)镃PU高速運(yùn)作時(shí)需要良好的散熱。
82、兩個(gè)程序員在聊天:“我昨天碰到個(gè)辣妹。我把她帶回家,馬上就開始如饑似渴地親吻,她就坐在我的鍵盤上,然后……” “你家里也有臺(tái)電腦?啥配置???”

87、程序員跟產(chǎn)品經(jīng)理一起看電視。每個(gè)節(jié)目看到一半程序員就換臺(tái),看到一半就換臺(tái),幾次之后產(chǎn)品經(jīng)理終于忍無可忍的咆哮:老子剛看出點(diǎn)意思你就換、剛看出點(diǎn)意思你就換,到底還讓不讓人看啦?!程序員淡定的盯著電視道:你半路改需求的時(shí)候我可沒吱過聲!
88、菜鳥:“我該怎么學(xué)習(xí)WEB編程呢?”大牛:“WEB編程就是一個(gè)程序員帶著兩個(gè)MM(MSSQL與MYSQL),玩3P(JSP,PHP,ASP),然后學(xué)著How to make love(HTML)..”
89、兩程序員向同一個(gè)MM求愛,MM說"去環(huán)游世界后再來找我!"。碼農(nóng)A立即收拾行李出發(fā)。碼農(nóng)B繞MM一圈,然后說"hello world!",立即感動(dòng)了MM。其實(shí)他只是習(xí)慣在做任何新事情前先確定hello world能跑通而已。
