AntiSamy防止xss攻击

可以使用AntiSamy防范XSS跨站脚本攻击



常用XSS方式分为以下几种：

1.      输入框中直接输入恶意脚本，如：

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

2.      输入框中输入html标签，在标签中嵌入恶意脚本，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.      将恶意脚本注入在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部分组成，1 服务台提供方， 2 服务注册方 3 服务消费分 4 监控部分

1. 注册方一般用zookeeper, 先下载安装，启动zkservece.cmd 会报错，需要修改配置文件 zoo.cfg. 路径中conf/下，，没有自己加一个。
正常启动

2. 编写一个服务器端, 创建maven项目

pom.xml文件

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

</project>

config/applicationProvider.xml  配置文件，里面定义了注册的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" />
    <!-- 注册地址 -->
     <dubbo:registry address="zookeeper://localhost:2181" />
     <dubbo:protocol name="dubbo" port="20880" />
        <!-- Service interface Concurrent Control -->
        <dubbo:service interface="cn.zto.service.IProcessData"    ref="demoService" executes="10" />
        <!-- designate implementation -->
        <bean id="demoService" class="cn.zto.service.impl.ProcessDataImpl" />
    </beans>
IProcessData定义接口及实现类
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);
}
启动服务
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("按任意键退出");
System.in.read();
}}
运行起来。如下
log4j:WARN No appenders could be found for logger (org.springframework.context.support.ClassPathXmlApplicationContext).
log4j:WARN Please initialize the log4j system properly.
按任意键退出



下面再建一个client程序
pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

注册的接口类，和要服务器端的包路径一致

package cn.zto.service;

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

客户端的配置文件，接口定义及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" />
    <!-- 注册地址 -->
     <dubbo:registry address="zookeeper://localhost:2181"/>
     <dubbo:consumer timeout="5000" />
     <dubbo:reference id="demoService" interface="cn.zto.service.IProcessData"/>
</beans>

客户端启动
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();
}



}


运行结果如下

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


这样就基本实现了dubbo的框架，很简单吧

spring boot
spring boot 是spring 4.0提供的微框架，支持 jdk 1.8, maven 3以上,  否则会报一些错误。

1. pom 文件， 主要写依赖关系，
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.example</groupId>
    <artifactId>spring-boot</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>spring-boot-example</name>
    
    <parent>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-parent</artifactId>
       <version>1.3.3.RELEASE</version>
    </parent>
    
    <!-- Add typical dependencies for a web application -->
    
    <dependencies>
        <dependency>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        
        
        
    </dependencies>

    <repositories>
        <repository>
            <id>spring-snapshots</id>
            <url>http://repo.spring.io/libs-snapshot</url>
        </repository>
    </repositories>

    <pluginRepositories>
        <pluginRepository>
            <id>spring-snapshots</id>
            <url>http://repo.spring.io/libs-snapshot</url>
        </pluginRepository>
    </pluginRepositories>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
</project>

2. 然后就是提供的接口类UserController， 实体类User， 主要是几个注解
@RestController   l类同spring mvc 的@Controller
@RequestMapping   类同spring mvc

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.  然后就是程序启动，这里不需要spring xml文件，完全依赖注解。
@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.  测试路径

http://localhost:8080/user/hello

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

Solr中的group与facet的区别
facet 自己理解就是分组聚合用的， 如下说明
 


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



Solr中的group与facet的区别

如果是简单的使用的话，那么Facet与group都可以用来进行数据的聚合查询，但是他们还是有很大的区别的。

首先上facet跟group的操作：

Facet的例子：

public voidFacetFieldQuery() throws Exception {

      solrServer = createSolrServer();

      SolrQueryquery = newSolrQuery();//建立一个新的查询

      query.setQuery("jobsName:计算机维护");

      query.setFacet(true);//设置facet=on

      // 分类信息分为：薪水，发布时间，教育背景，工作经验，公司类型，工作类型

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

            "educateBackground","jobExperience","companytype","jobsType" });//设置需要facet的字段

      query.setFacetLimit(10);// 限制facet返回的数量

      query.setFacetMissing(false);//不统计null的值

      query.setFacetMinCount(1);// 设置返回的数据中每个分组的数据最小值，比如设置为1，则统计数量最小为1，不然不显示

 

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

      QueryResponseresponse = solrServer.query(query);

      System.out.println("查询时间：" + 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();

      }

 

   }

运行结果如下：

查询时间：66

Group查询：

/**group查询

    * @throws Exception

    */

   public void GroupFieldQuery() throws Exception {

      solrServer = createSolrServer();

       SolrQuery query = new SolrQuery("jobsName:计算机维护");

        // 设置通过facet查询为true，表示查询时使用facet机制

        query.setParam(GroupParams.GROUP,true);   

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

        // 设置每个quality对应的

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

        // 设置返回doc文档数据，因只需要数量，故设置为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查询..."+group.getGroupValue()+"数量为："+group.getResult().getNumFound());

              }   

          }   

            }   

        }

 

   }

group查询...面议数量为：6882

group查询...4500-5999数量为：75

group查询...2001-4000数量为：1508

group查询...其他数量为：671

group查询...2000-2999数量为：181

group查询...4001-6000数量为：536

group查询...2000-4000数量为：19

group查询...2000-3000数量为：34

group查询...3000-4499数量为：224

group查询...3000-5000数量为：82

 

facet的查询结果主要是分组信息：有什么分组，每个分组包括多少记录；但是分组中有哪些数据是不可知道的，只有进一步搜索。
group则类似于关系数据库的group by，可以用于一个或者几个字段去重、显示一个group的前几条记录等。

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

 

两者其实用起来还是有比较大的区别的，但是如果说区别的话可以看下wiki上的这段

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)

 

下面这两个查询语句一个是facet的一个是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查询出的如下：（只截取部分结果）




根据条件查询出的是查询结果，facet是聚类后的信息跟查询条件是分开的，查询结果也跟facet没关系。

但是下面看group查询的




也就是你的查询条件是跟group相关的，返回的查询结果也是跟group相关的，比如说你想要查询的结果在每个分组中 都有数据采集，那么就最好用group，这样出来的数据跟group也是相关的，但是有个问题，比如说你要查询group每个采集1个，ok那么你查询的 时候的条件rows就无效了（也不能说无效，主要是看你怎么使用），就是最多每个分组给你返回一个，多了没有了。

再细说点就是如果你想查询归查询聚类归聚类，那么使用facet，如果想使用类似采集的效果，每个group分组采集多少个，那么使用group查询。
