redis和spring的集成

Jedis是Redis的Java版本的客户端实现。
一、我们需要导入jar包（下面是最新版本，可根据情况自行选择版本）
[html] view plain copy
<!-- https://mvnrepository.com/artifact/redis.clients/jedis -->  
<dependency>  
    <groupId>redis.clients</groupId>  
    <artifactId>jedis</artifactId>  
    <version>2.9.0</version>  
</dependency>  
也可自行下载
jedisAPI文档：http://tool.oschina.NET/uploads/apidocs/
二、配置spring-redis.xml配置文件
1.spring-redis.xml
[html] view plain copy
<?xml version="1.0" encoding="GBK"?>  
<!DOCTYPE beans PUBLIC "-//SPRING/DTD BEAN/EN"  
 "http://www.springframework.org/dtd/spring-beans.dtd">  
<beans default-lazy-init="false">  
    <description>REDIS缓存配置</description>  
  
    <!-- JEDIS SHARD 池配置 -->  
    <bean id="shardedJedisPool" class="redis.clients.jedis.ShardedJedisPool">  
        <constructor-arg index="0" ref="jedisPoolConfig" />  
        <constructor-arg index="1">  
            <list>  
                <ref bean="jedis.shardInfo.default" />  
            </list>  
        </constructor-arg>  
    </bean>  
  
    <!-- JEDIS连接池配置 -->  
    <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">  
        <property name="maxTotal" value="100" />  
        <property name="maxIdle" value="20" />  
        <property name="maxWaitMillis" value="5000" />  
        <property name="testOnBorrow" value="true" />  
    </bean>  
  
    <!-- JEDIS SHARD信息配置[START]      在此添加REDIS集群配置 -->  
    <bean id="jedis.shardInfo.default" class="redis.clients.jedis.JedisShardInfo">  
        <constructor-arg index="0" value="192.168.1.21" />  
        <constructor-arg index="1" type="int" value="6379" />  
        <constructor-arg index="2" type="java.lang.String" value="192.168.1.21" />  
    </bean>  
    <!-- JEDIS SHARD信息配置 [END] -->  
</beans>  
2.spring-core.xml
[html] view plain copy
<?xml version="1.0" encoding="UTF-8"?>  
<beans xmlns="http://www.springframework.org/schema/beans"  
    xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"  
    xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:tx="http://www.springframework.org/schema/tx"  
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
    xsi:schemaLocation="http://www.springframework.org/schema/beans    
      http://www.springframework.org/schema/beans/spring-beans-3.2.xsd    
      http://www.springframework.org/schema/context    
      http://www.springframework.org/schema/context/spring-context-3.2.xsd    
      http://www.springframework.org/schema/mvc    
      http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd    
      http://www.springframework.org/schema/tx    
      http://www.springframework.org/schema/tx/spring-tx-3.2.xsd      
      http://www.springframework.org/schema/aop   
      http://www.springframework.org/schema/aop/spring-aop-3.2.xsd">  
    <import resource="spring-redis.xml"/>  
      
</beans>    
个人习惯将spring配置文件按需求划分开，然后在配置在一个spring中实现，这样可以更好的维护每个spring模块
3.将shardedJedisPool注入相关的类中即可使用
[plain] view plain copy
public class RedisTest {  
    @Autowired  
    private ShardedJedisPool shardedJedisPool;  
    @Test  
    public void testSet() {  
        ShardedJedis jedis = shardedJedisPool.getResource();  
        jedis.set("name", "test");  
    }  
    @Test  
    public void testGet() {  
        ShardedJedis jedis = shardedJedisPool.getResource();  
        String name = jedis.get("name");  
        System.out.println(name);  
    }  
}  
4.实现redis的封装
我们每次将shardedJedisPool注入到相关类中会比较麻烦，我们需要集成一个封装方法，方便redis的实现
在spring-redis中添加
[html] view plain copy
<!-- 缓存代理，使用缓存内容请使用本代理进行操作 请使用接口进行注入 -->  
    <bean id="cacheProxy" class="com.yuanding.common.cache.CacheProxy">  
        <property name="shardedJedisPool">  
            <ref bean="shardedJedisPool" />  
        </property>  
    </bean>  
实现cacheProxy类继承ShardedRedisProxy类
[java] view plain copy
package com.yuanding.common.cache;  
  
/** 
 *  
 * 缓存代理 
 *  
 */  
public class CacheProxy{  
    //TODO 这里可以继承ShardedJedisPool的实现类  
    ...  
}  
三、shardedJedisPool的java实现与jedis客户端的封装类
1.IRedisProxy缓存代理接口
[java] view plain copy
package com.yuanding.common.cache;  
  
import java.util.List;  
import java.util.Map;  
import java.util.Set;  
  
/**

 * 4、以Z开头的为ZSET（有序集合）操作命令

CacheProxy继承接口IRedisProxy
[java] view plain copy
package com.yuanding.common.cache;  
  
/** 
 *  
 * 缓存代理 
 *  
 */  
public class CacheProxy extends ShardedRedisProxy{  
    //TODO 继承ShardedRedisProxy缓存代理的方法  
    ...  
}  

这样我们就可以实现封装的接口
使用封装接口的好处就是ShardedJedisPool缓存池执行的时候总会出现一些问题，抛出一些bug，不使用try catch将错误抛出，就会出现莫名其妙的问题
