    Zh都爱Spring加Hibernate?br />    但Spring MVC+hibernate的Sample如Appfuse的代码却不得最z优好读，如果在自q目中l发挥我们最擅长的依L葫芦大法Q美好愿望未必会实现?
     所以，Pramatic_不灭。这个系列就是探L适合自己的Spring+Hibernate模式?br />    
                              I-配置文g?/strong>

     我厌倦一切配|文件繁重的框架?
     最好的情况是，框架提供极端灉|复杂的配|方式，但只在你需要的时?/strong>?br /> 
     Spring提供了三U可能来化XML。随着国内用户水^的提高，q些基本的简化技巧大安已掌握?br />     大家可以直接看第3Q第4?-Spring 1.2, Spring 2.0的后l改q?/p>

1.1.autowire="byName" /"byType"

     假设Controller有一个属性名为customerDAOQSpring׃在配|文仉查找有没有名字ؓCustomerDAO的bean, 自动为Controller注入?br />     如果bean有两个属性，一个想默认注入Q一个想自定义，只要讑֮了autowireQ然后显式的声明那个惌定义的，可以达到要求。这应了需求，在需要特别配|的时候就提供配置Q否则给我一个默认注入?br />
     q有一个更懒的地方Q在最最栚w?lt;beans>节点写一句default-autovwrie="byName"Q可以让文g里的所有bean 都默认autowrie?br />    不过Rod认ؓ开发期可以q样Q但Production Server上不应该使用Autowire。而我觉得那些自定义一ơ的地方比如TranscationManager应该详细定义Q而Dao,Controllerq种大量重复定义的bean可以偷Ҏ了?/p>

1.2.<bean>节点之间抽象公共定义?Inner Bean

    q太方便懒h了，想不C个独立的XML节点都可以玩l承和派生，子节Ҏ有父节点的全部属性?br />    最好用的地方就是那个Transtion Proxy的定义。先定义一个又长又冗的父类Q然后用子类ȝ承它?br />   
    另外Q还有一个Inner Bean的机Ӟ可以把DAO写成Proxy的内部类。ؓ什么要写成内部c?Z让Proxy冒名替它去让Controller Autowire?详见后面的示?

1.3. 宽松的配|? To XML or Not to XML 
    据说Spring比Struts的配|宽松了很多Q这q人把东西从配|文件中撤回原码中的Z?br />    不赞成什么都往配置文g里晒Q造成了Rich Information的配|文Ӟ修改或者查看的时候，要同时打开配置文g和原码才能清楚一切?
    而我希望配置文g集中做一些整体的配置Q还有框架必ȝ、无需理的冗余代码。而一些细节的变化不大的配|和逻辑Q就量别往里塞了。因此，Success/Fail View 的配|，不徏议放在里面?/p>

2.化后的配|文?/strong>

1.Controller只剩下一?/p> 

<bean name="customerController" class="org.springside.bookstore.web.CustomerController" autowire="byName"/>

 

2.DAO也只剩一?/p> 

<bean id="customerDAO" class="org.springside.bookstore.dao.CustomerDao"/>

 

3.Servicecd剩下5?

  <bean id="customerManager" parent="baseTxService">
        <property name="target">
            <bean class="org.springside.bookstore.service.CustomerManager"/>
        </property>
    </bean>

 

3.Spring 1.2后xml语法?br />
 最主要的简化是把属性值和引用bean?strong>子节?/strong>变回?strong>属性?/strong>Q对不喜Ƣautowire的兄弟比较有用?br /> 当然Q如果value要CDATA的时候还是要用子节点。另外，list的值可以用I格隔开也比较实用?/p>

1.属性?br />
  <property name="foo">
  <value>fooValue</value>
  </property>
  化ؓ
  <property name="foo" value="fooValue"/>
 
2.引用 bean
<property name="foo">
<ref bean="fooBean">
</property>
化ؓ
<property name="foo" ref="fooBean"/>
 

3. list可以化ؓI格分开的字W串
  
<property name="myFriendList">
 <list>
   <value>gigix</value>
        <value>wuyu</value>
 </list>
</property>
化ؓ
<property name="myFriendList" value="gigix wuyu"/>
    
  
4.Spring 2.0来了
   如果没什么外力刺ȀQspring xml 可能p样不会变了。但现在xml成了q街老鼠Q被ror的默认配|和JDK5的annotation逼得不行Q当然就要l求变?br />   比如有好事者认为，节点名必Mbean打头Q附加一个属性id来表Cbean名；属性值必L一个property子节点，子节点上有个属性name来表C属性名Q是l机器看的很不直观的东西?
<bean id="customerDAO" class="org.springside...CustomerDAO">
 <property name="maxCount" value="10">
</bean>
 
lh看的东西应该写?
<customerDAO class="org.springside....CustomerDAO" maxCount="10"/>
 

Spring 2.0正用schema实现cM的语法，具体L它的JPetStore sample?br />
5.使用Spring自带的DTD使编辑器Smart.

    如果没有用Eclipse的Spring插gQ那臛_也要使用spring自带的dtd使XML~辑器smart一些，能够自动Z生成属?判断节点/属性名U有没有拼错{?br />
6.q有更变态的化配|方?/strong>
    比如autoproxyQ不q我觉得更简化就不可控了Q所以没有采用?/p>

声明Q本文系JavaEye|站发布的原创博客文章，未经作者书面许可，严禁M|站转蝲本文Q否则必追I法律责任！

本文为本人在工作学习中的ȝQ每个方法都l过试Q记在博客上一斚w是ؓ了自己日后工作方便，另一斚w是ؓ了给大家提供方便Q节U时间?/p>

 一.获得控制台用戯入的信息

/** *//**获得控制台用戯入的信息
     * @return
     * @throws IOException
     */
    public String getInputMessage() throws IOException{
        System.out.println("误入您的命令∶");
        byte buffer[]=new byte[1024];
        int count=System.in.read(buffer);
        char[] ch=new char[count-2];//最后两位ؓl束W，删去不要
        for(int i=0;i<count-2;i++)
            ch[i]=(char)buffer[i];
        String str=new String(ch);
        return str;
    }

 

可以q回用户输入的信息，不之处在于不支持中文输入，有待q一步改q?/p>

?复制文g

1.以文件流的方式复制文?/p> 

/** *//**以文件流的方式复制文?
     * @param src 文g源目?
     * @param dest 文g目的目录
     * @throws IOException  
     */
    public void copyFile(String src,String dest) throws IOException{
        FileInputStream in=new FileInputStream(src);
        File file=new File(dest);
        if(!file.exists())
            file.createNewFile();
        FileOutputStream out=new FileOutputStream(file);
        int c;
        byte buffer[]=new byte[1024];
        while((c=in.read(buffer))!=-1){
            for(int i=0;i<c;i++)
                out.write(buffer[i]);        
        }
        in.close();
        out.close();
    }

 

该方法经q测试，支持中文处理Qƈ且可以复制多U类型，比如txtQxmlQjpgQdoc{多U格?/p>

?写文?/p>

1.利用PrintStream写文?/p> 

/** *//**
     * 文g输出CZ
     */
    public void PrintStreamDemo(){
        try {
            FileOutputStream out=new FileOutputStream("D:/test.txt");
            PrintStream p=new PrintStream(out);
            for(int i=0;i<10;i++)
                p.println("This is "+i+" line");
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
    }

 

2.利用StringBuffer写文?/p> 

public void StringBufferDemo() throws IOException{
        File file=new File("/root/sms.log");
        if(!file.exists())
            file.createNewFile();
        FileOutputStream out=new FileOutputStream(file,true);        
        for(int i=0;i<10000;i++){
            StringBuffer sb=new StringBuffer();
            sb.append("q是W?+i+"?前面介绍的各U方法都不关?Z么L奇怪的问题 ");
            out.write(sb.toString().getBytes("utf-8"));
        }        
        out.close();
    }

 

该方法可以设定用何U编码，有效解决中文问题?/p>

?文g重命?/p>

 

 /** *//**文g重命?
     * @param path 文g目录
     * @param oldname  原来的文件名
     * @param newname 新文件名
     */
    public void renameFile(String path,String oldname,String newname){
        if(!oldname.equals(newname)){//新的文g名和以前文g名不同时,才有必要q行重命?
            File oldfile=new File(path+"/"+oldname);
            File newfile=new File(path+"/"+newname);
            if(newfile.exists())//若在该目录下已经有一个文件和新文件名相同Q则不允讔R命名
                System.out.println(newname+"已经存在Q?);
            else{
                oldfile.renameTo(newfile);
            } 
        }         
    }

    

?转移文g目录
 

转移文g目录不等同于复制文gQ复制文件是复制后两个目录都存在该文Ӟ而{UL件目录则是{UdQ只有新目录中存在该文g?

  

  /** *//**转移文g目录
     * @param filename 文g?
     * @param oldpath 旧目?
     * @param newpath 新目?
     * @param cover 若新目录下存在和转移文gh相同文g名的文gӞ是否覆盖新目录下文gQcover=true会覆盖原文Ӟ否则不操?
     */
    public void changeDirectory(String filename,String oldpath,String newpath,boolean cover){
        if(!oldpath.equals(newpath)){
            File oldfile=new File(oldpath+"/"+filename);
            File newfile=new File(newpath+"/"+filename);
            if(newfile.exists()){//若在待{Uȝ录下Q已l存在待转移文g
                if(cover)//覆盖
                    oldfile.renameTo(newfile);
                else
                    System.out.println("在新目录下已l存在："+filename);
            }
            else{
                oldfile.renameTo(newfile);
            }
        }       
    }

  

?L?/p>

1.利用FileInputStreamd文g


   

 /** *//**L?
     * @param path
     * @return
     * @throws IOException
     */
    public String FileInputStreamDemo(String path) throws IOException{
        File file=new File(path);
        if(!file.exists()||file.isDirectory())
            throw new FileNotFoundException();
        FileInputStream fis=new FileInputStream(file);
        byte[] buf = new byte[1024];
        StringBuffer sb=new StringBuffer();
        while((fis.read(buf))!=-1){
            sb.append(new String(buf));    
            buf=new byte[1024];//重新生成Q避免和上次d的数据重?
        }
        return sb.toString();
    }

 


2.利用BufferedReaderd

在IO操作Q利用BufferedReader和BufferedWriter效率会更高一?

  

  /** *//**L?
     * @param path
     * @return
     * @throws IOException
     */
    public String BufferedReaderDemo(String path) throws IOException{
        File file=new File(path);
        if(!file.exists()||file.isDirectory())
            throw new FileNotFoundException();
        BufferedReader br=new BufferedReader(new FileReader(file));
        String temp=null;
        StringBuffer sb=new StringBuffer();
        temp=br.readLine();
        while(temp!=null){
            sb.append(temp+" ");
            temp=br.readLine();
        }
        return sb.toString();
    }

 
3.利用dom4jdxml文g

  

  /** *//**从目录中dxml文g
     * @param path 文g目录
     * @return
     * @throws DocumentException
     * @throws IOException
     */
    public Document readXml(String path) throws DocumentException, IOException{
        File file=new File(path);
        BufferedReader bufferedreader = new BufferedReader(new FileReader(file));
        SAXReader saxreader = new SAXReader();
        Document document = (Document)saxreader.read(bufferedreader);
        bufferedreader.close();
        return document;
    }

  

?创徏文g(文g?

1.创徏文g?nbsp;  

  /** *//**创徏文g?
      * @param path  目录
    */
    public void createDir(String path){
        File dir=new File(path);
        if(!dir.exists())
            dir.mkdir();
    }

   

2.创徏新文?

/** *//**创徏新文?
     * @param path 目录
     * @param filename 文g?
     * @throws IOException
     */
    public void createFile(String path,String filename) throws IOException{
        File file=new File(path+"/"+filename);
        if(!file.exists())
            file.createNewFile();
    }

 

?删除文g(目录)

1.删除文g     

/** *//**删除文g
     * @param path 目录
     * @param filename 文g?
     */
    public void delFile(String path,String filename){
        File file=new File(path+"/"+filename);
        if(file.exists()&&file.isFile())
            file.delete();
    }

 

2.删除目录
要利用Filecȝdelete()Ҏ删除目录Ӟ必须保证该目录下没有文g或者子目录Q否则删除失败，因此在实际应用中Q我们要删除目录Q必d用递归删除该目录下的所有子目录和文Ӟ然后再删除该目录?nbsp; 

/** *//**递归删除文g?
     * @param path
     */
    public void delDir(String path){
        File dir=new File(path);
        if(dir.exists()){
            File[] tmp=dir.listFiles();
            for(int i=0;i<tmp.length;i++){
                if(tmp[i].isDirectory()){
                    delDir(path+"/"+tmp[i].getName());
                }
                else{
                    tmp[i].delete();
                }
            }
            dir.delete();
        }
    }

使用~写可以帮助减少你CSS文g的大，更加Ҏ阅读。css~写的主要规则如下：

颜色

16q制的色彩|如果每两位的值相同，可以~写一半，例如Q?/p>

#000000可以~写?000;#336699可以~写?369;

盒尺?/h4>

通常有下面四U书写方?

property:value1; 表示所有边都是一个值value1Q?
property:value1 value2; 表示top和bottom的值是value1,right和left的值是value2
property:value1 value2 value3; 表示top的值是value1Qright和left的值是value2Qbottom的值是value3
property:value1 value2 value3 value4; 四个gơ表Ctop,right,bottom,left
方便的记忆方法是时针，上右下左。具体应用在margin和padding的例子如下：

margin:1em 0 2em 0.5em;

Ҏ(border)

Ҏ的属性如下：

border-width:1px;
border-style:solid;
border-color:#000;

可以~写Z句：border:1px solid #000;
语法是border:width style color;

语法是background:color image repeat attachment position;
你可以省略其中一个或多个属性|如果省略Q该属性值将用浏览器默认|默认gؓQ?/p>

color: transparent
image: none
repeat: repeat
attachment: scroll
position: 0% 0%

字体(fonts)

字体的属性如下：

font-style:italic;
font-variant:small-caps;
