PhoneGap與Jquery Mobile組合開(kāi)發(fā)android應(yīng)用的配置

jfinal+freemarker+jquery mobile 開(kāi)發(fā)出web應(yīng)用，然后找個(gè)殼子打包成apk應(yīng)用。

AntiSamy防止xss攻擊

可以使用AntiSamy防范XSS跨站腳本攻擊

常用XSS方式分為以下幾種：

1. 輸入框中直接輸入惡意腳本，如：

><script>alert(document.cookie)</script>

2. 輸入框中輸入html標(biāo)簽，在標(biāo)簽中嵌入惡意腳本，如src，href，css style等。

<IMG SRC="javascript：alert('XSS');">; <BODY BACKGROUND="javascript：alert('XSS')"> <STYLE>li {list-style-image:url("javascript：alert('XSS')");}</STYLE><UL><LI>XSS</br>

3. 將惡意腳本注入在event事件中，如onClick，onBlur，onMouseOver等事件。

<a onmouseover="alert(document.cookie)">xxslink</a>

4. 在remote style sheet，javascript中，如

<LINK REL="stylesheet"HREF="javascript：alert('XSS');">

dubbo

dubbo是阿里巴巴的框架，主要有4部分組成，1 服務(wù)臺(tái)提供方， 2 服務(wù)注冊(cè)方 3 服務(wù)消費(fèi)分 4 監(jiān)控部分

1. 注冊(cè)方一般用zookeeper, 先下載安裝，啟動(dòng)zkservece.cmd 會(huì)報(bào)錯(cuò)，需要修改配置文件 zoo.cfg. 路徑中conf/下，，沒(méi)有自己加一個(gè)。
正常啟動(dòng)

2. 編寫一個(gè)服務(wù)器端, 創(chuàng)建maven項(xiàng)目

</project>

config/applicationProvider.xml 配置文件，里面定義了注冊(cè)的bean, 和zookeeper的地址

<?xml version="1.0" encoding="UTF-8"?>
<beans
    xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"   xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd ">
    <dubbo:application name="hello-world" />
    
     <dubbo:registry address="zookeeper://localhost:2181" />
     <dubbo:protocol name="dubbo" port="20880" />
        
        <dubbo:service interface="cn.zto.service.IProcessData"   ref="demoService" executes="10" />
        
        <bean id="demoService" class="cn.zto.service.impl.ProcessDataImpl" />
    </beans>

IProcessData定義接口及實(shí)現(xiàn)類

package cn.zto.service.impl;

import cn.zto.service.IProcessData;
public class ProcessDataImpl implements IProcessData {
public String hello(String name) {
System.out.println(name);
return "hello : " + name;
}}

package cn.zto.service;

public interface IProcessData {
public String hello(String name);
}

啟動(dòng)服務(wù)

package cn.zto.app;

import org.springframework.context.support.ClassPathXmlApplicationContext;
public class Main {
public static void main(String[] args) throws Exception {
ClassPathXmlApplicationContext context=new ClassPathXmlApplicationContext( new String[] {
"config/applicationProvider.xml"
});
context.start();
System.out.println("按任意鍵退出");
System.in.read();
}}

運(yùn)行起來(lái)。如下

log4j:WARN No appenders could be found for logger (org.springframework.context.support.ClassPathXmlApplicationContext).
log4j:WARN Please initialize the log4j system properly.
按任意鍵退出

下面再建一個(gè)client程序

注冊(cè)的接口類，和要服務(wù)器端的包路徑一致

package cn.zto.service;

public interface IProcessData {
public String hello(String name);
}

客戶端的配置文件，接口定義及zookeeper的地址

<?xml version="1.0" encoding="UTF-8"?>
<beans
    xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"   xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd ">
    <dubbo:application name="consumer-of-helloworld-app" />
    
     <dubbo:registry address="zookeeper://localhost:2181"/>
     <dubbo:consumer timeout="5000" />
     <dubbo:reference id="demoService" interface="cn.zto.service.IProcessData"/>
</beans>

客戶端啟動(dòng)

package cn.zto.consumer;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import cn.zto.service.IProcessData;

public class ConsumerThd{



public void sayHello(){
ClassPathXmlApplicationContext context=new ClassPathXmlApplicationContext(
new String[] {"config/applicationProvider.xml"});
context.start();
IProcessData demoService=(IProcessData) context.getBean("demoService");
System.out.println(demoService.hello("world"));
}

public static void main(String args[]){
   new ConsumerThd().sayHello();
}

}

運(yùn)行結(jié)果如下

log4j:WARN No appenders could be found for logger (org.springframework.context.support.ClassPathXmlApplicationContext).
log4j:WARN Please initialize the log4j system properly.
hello : world

這樣就基本實(shí)現(xiàn)了dubbo的框架，很簡(jiǎn)單吧

spring boot

spring boot 是spring 4.0提供的微框架，支持 jdk 1.8, maven 3以上, 否則會(huì)報(bào)一些錯(cuò)誤。

1. pom 文件，主要寫依賴關(guān)系，

package two;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/user")

public class UserController {

   @RequestMapping("/hello")
   public User view(){

       User user=new User();
       user.setId((long)100);
       user.setName("fanjs");
       return user;


   }

package two;

public class User {
private Long id;
private String name;
public Long getId() {
   return id;
}
public void setId(Long id) {
   this.id = id;
}
public String getName() {
   return name;
}
public void setName(String name) {
   this.name = name;
}

3. 然后就是程序啟動(dòng)，這里不需要spring xml文件，完全依賴注解。
@EnableAutoConfiguration
@Configuration
@ComponentScan

package two;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

@Configuration
@ComponentScan
@EnableAutoConfiguration

public class RunMain {

   /**
   * @param args
   */
   public static void main(String[] args) {
       // TODO Auto-generated method stub

       SpringApplication.run(RunMain.class, args);
   }

}

4. 測(cè)試路徑

http://localhost:8080/user/hello

{"id":100,"name":"fanjs"}

Solr中的group與facet的區(qū)別

facet 自己理解就是分組聚合用的，如下說(shuō)明

http://blog.csdn.net/a925907195/article/details/47257243

Solr中的group與facet的區(qū)別

如果是簡(jiǎn)單的使用的話，那么Facet與group都可以用來(lái)進(jìn)行數(shù)據(jù)的聚合查詢，但是他們還是有很大的區(qū)別的。

首先上facet跟group的操作：

Facet的例子：

public voidFacetFieldQuery() throws Exception {

solrServer = createSolrServer();

SolrQueryquery = newSolrQuery();//建立一個(gè)新的查詢

query.setQuery("jobsName:計(jì)算機(jī)維護(hù)");

query.setFacet(true);//設(shè)置facet=on

// 分類信息分為：薪水，發(fā)布時(shí)間，教育背景，工作經(jīng)驗(yàn)，公司類型，工作類型

query.addFacetField(new String[] {"salary","publishDate",

"educateBackground","jobExperience","companytype","jobsType" });//設(shè)置需要facet的字段

query.setFacetLimit(10);// 限制facet返回的數(shù)量

query.setFacetMissing(false);//不統(tǒng)計(jì)null的值

query.setFacetMinCount(1);// 設(shè)置返回的數(shù)據(jù)中每個(gè)分組的數(shù)據(jù)最小值，比如設(shè)置為1，則統(tǒng)計(jì)數(shù)量最小為1，不然不顯示

//query.addFacetQuery("publishDate:[2014-04-11T00:00:00Z TO2014-04-13T00:00:00Z]");

QueryResponseresponse = solrServer.query(query);

System.out.println("查詢時(shí)間：" + response.getQTime());

List<FacetField>facets = response.getFacetFields();//返回的facet列表

for (FacetField facet :facets) {

System.out.println(facet.getName());

System.out.println("----------------");

List<Count>counts = facet.getValues();

for (Count count : counts){

System.out.println(count.getName()+":"+ count.getCount());

}

System.out.println();

}

運(yùn)行結(jié)果如下：

查詢時(shí)間：66

Group查詢：

/**group查詢

* @throws Exception

public void GroupFieldQuery() throws Exception {

solrServer = createSolrServer();

SolrQuery query = new SolrQuery("jobsName:計(jì)算機(jī)維護(hù)");

// 設(shè)置通過(guò)facet查詢?yōu)?/span>true，表示查詢時(shí)使用facet機(jī)制

query.setParam(GroupParams.GROUP,true);

query.setParam(GroupParams.GROUP_FIELD,"salary");

// 設(shè)置每個(gè)quality對(duì)應(yīng)的

query.setParam(GroupParams.GROUP_LIMIT,"1");

// 設(shè)置返回doc文檔數(shù)據(jù)，因只需要數(shù)量，故設(shè)置為0

query.setRows(10);

QueryResponse response = solrServer.query(query);

if (response !=null) {

GroupResponse groupResponse =response.getGroupResponse();

if(groupResponse !=null) {

List<GroupCommand> groupList =groupResponse.getValues();

for(GroupCommand groupCommand : groupList){

List<Group> groups =groupCommand.getValues();

for(Group group : groups) {

System.out.println("group查詢..."+group.getGroupValue()+"數(shù)量為："+group.getResult().getNumFound());

}

group查詢...面議數(shù)量為：6882

group查詢...4500-5999數(shù)量為：75

group查詢...2001-4000數(shù)量為：1508

group查詢...其他數(shù)量為：671

group查詢...2000-2999數(shù)量為：181

group查詢...4001-6000數(shù)量為：536

group查詢...2000-4000數(shù)量為：19

group查詢...2000-3000數(shù)量為：34

group查詢...3000-4499數(shù)量為：224

group查詢...3000-5000數(shù)量為：82

facet的查詢結(jié)果主要是分組信息：有什么分組，每個(gè)分組包括多少記錄；但是分組中有哪些數(shù)據(jù)是不可知道的，只有進(jìn)一步搜索。
group則類似于關(guān)系數(shù)據(jù)庫(kù)的group by，可以用于一個(gè)或者幾個(gè)字段去重、顯示一個(gè)group的前幾條記錄等。

The Grouping feature only works if groups are inthe same shard. You must use the custom sharding feature to use the Groupingfeature.

兩者其實(shí)用起來(lái)還是有比較大的區(qū)別的，但是如果說(shuō)區(qū)別的話可以看下wiki上的這段

Field Collapsing and Result Grouping aredifferent ways to think about the same Solr feature.

Field Collapsing collapsesa group of results with the same field value down to a single (or fixed number)of entries. For example, most search engines such as Google collapse on site soonly one or two entries are shown, along with a link to click to see moreresults from that site. Field collapsing can also be used to suppress duplicatedocuments.

Result Grouping groupsdocuments with a common field value into groups, returning the top documentsper group, and the top groups based on what documents are in the groups. Oneexample is a search at Best Buy for a common term such as DVD, that shows thetop 3 results for each category ("TVs &Video","Movies","Computers", etc)

下面這兩個(gè)查詢語(yǔ)句一個(gè)是facet的一個(gè)是group的

http://localhost:8080/solr/JobsOtherWeb0/select?q=jobsName%3A%E8%AE%A1%E7%AE%97%E6%9C%BA%E7%BB%B4%E6%8A%A4&group=true&group.field=salary&group.limit=1&rows=10

http://localhost:8080/solr/JobsOtherWeb0/select?q=jobsName%3A%E8%AE%A1%E7%AE%97%E6%9C%BA%E7%BB%B4%E6%8A%A4&facet=true&facet.field=salary&facet.field=publishDate&facet.field=educateBackground&facet.field=jobExperience&facet.field=companytype&facet.field=jobsType&facet.limit=10&facet.missing=false&facet.mincount=1

其中facet查詢出的如下：（只截取部分結(jié)果）

根據(jù)條件查詢出的是查詢結(jié)果，facet是聚類后的信息跟查詢條件是分開(kāi)的，查詢結(jié)果也跟facet沒(méi)關(guān)系。

但是下面看group查詢的

也就是你的查詢條件是跟group相關(guān)的，返回的查詢結(jié)果也是跟group相關(guān)的，比如說(shuō)你想要查詢的結(jié)果在每個(gè)分組中都有數(shù)據(jù)采集，那么就最好用group，這樣出來(lái)的數(shù)據(jù)跟group也是相關(guān)的，但是有個(gè)問(wèn)題，比如說(shuō)你要查詢group每個(gè)采集1個(gè)，ok那么你查詢的時(shí)候的條件rows就無(wú)效了（也不能說(shuō)無(wú)效，主要是看你怎么使用），就是最多每個(gè)分組給你返回一個(gè)，多了沒(méi)有了。

再細(xì)說(shuō)點(diǎn)就是如果你想查詢歸查詢聚類歸聚類，那么使用facet，如果想使用類似采集的效果，每個(gè)group分組采集多少個(gè)，那么使用group查詢。
