### 配置所需jar包 ###

<dependency>
       <groupId>redis.clients</groupId>
       <artifactId>jedis</artifactId>
       <version>2.7.3</version>
    </dependency>
    
    <dependency>
       <groupId>org.springframework.data</groupId>
       <artifactId>spring-data-redis</artifactId>
       <version>1.6.0.RELEASE</version>
    </dependency>

### redis.properties ###

#redis的服务器地址
    redis.host=127.0.0.1
    #redis的服务端口
    redis.port=6379
    #密码
    redis.password=123456
    
    #最大连接数
    redis.maxActive=300
    #最大空闲数
    redis.maxIdle=100
    #最大建立连接等待时间
    redis.maxWaitMillis=1000

### spring-redis.xml ###

<?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:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">
        
        
        <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
            <property name="maxTotal" value="${redis.maxActive}"/>
            <property name="maxIdle" value="${redis.maxIdle}"/>
            <property name="maxWaitMillis" value="${redis.maxWaitMillis}"/>
            <property name="testOnBorrow" value="true"/>
        </bean>
    
        
        <bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
            <property name="hostName" value="${redis.host}"/>
            <property name="port" value="${redis.port}"/>
            <property name="password" value="${redis.password}"/>
            <property name="poolConfig" ref="jedisPoolConfig"/>
        </bean>
    
        
        <bean id="redisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate">
            <property name="connectionFactory" ref="jedisConnectionFactory"/>
        </bean>
    </beans>

### 简单测试 ###

package com.test.web;
    
    import org.springframework.ui.Model;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    import javax.servlet.http.HttpServletRequest;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.data.redis.core.RedisTemplate;
    import org.springframework.data.redis.serializer.RedisSerializer;
    
    @Controller
    @RequestMapping("/test")
    public class TestController { 
        @Autowired
        private RedisTemplate rt;
    
        @RequestMapping(value="/info", method = RequestMethod.GET)
        private void info(){ 
            String name = "test";
            //存入redis
            rt.opsForValue().set("name", name);
            //从redis取出对应值
            Object redis_name = rt.opsForValue().get("name");
    
            Sysout.out.println(redis_name);
        }
    }
    
    //输出test
