1.添加maven依赖:(注意:spring-data-redis包的版本要与spring的版本一致哦!)

<dependency>
    			<groupId>org.springframework.data</groupId>
    			<artifactId>spring-data-redis</artifactId>
    			<version>1.8.4.RELEASE</version>
    		</dependency>
    
    
    
    		
    		<dependency>
    			<groupId>redis.clients</groupId>
    			<artifactId>jedis</artifactId>
    			<version>2.9.0</version>
    		</dependency>

2.redis.properties 配置文件

redis.host=127.0.0.1  #IP地址
    redis.port=6379  #端口号
    redis.password=  #密码为空
    
    redis.maxIdle=300 #最大空闲连接数
    redis.maxWaitMillis=1000 #连接时的最大等待毫秒数,小于零:阻塞不确定的时间,默认-1
    redis.maxTotal=600 #最大活动对象数 
    redis.testOnBorrow=true #获取连接的时候检查有效性, 默认false
    redis.testOnReturn=true #调用return Object方法时，是否进行有效性检查

### 3.配置application-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:p="http://www.springframework.org/schema/p"

        ">
    	
    	<context:property-placeholder location="classpath:redis.properties" />
    
    	
    	<bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig">
    		<property name="maxIdle" value="${redis.maxIdle}" />
    		<property name="maxTotal" value="${redis.maxTotal}" />

    		<property name="testOnReturn" value="${redis.testOnReturn}" />
    	</bean>
    
    	
    	<bean id="connectionFactory"
    		class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"
    		p:hostName="${redis.host}" p:port="${redis.port}" p:password="${redis.password}"
    		p:pool-config-ref="poolConfig" p:timeout="100000" />
    
    
    	
    	<bean id="redisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate">
    		<property name="connectionFactory" ref="connectionFactory" />
    		
    		<property name="keySerializer">
    			<bean
    				class="org.springframework.data.redis.serializer.StringRedisSerializer" />
    		</property>
    		<property name="valueSerializer">
    			<bean
    				class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer" />
    		</property>
    	</bean>
    </beans>

### 4.单元测试redis ###

import java.util.logging.Logger;
    
    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.data.redis.core.RedisTemplate;
    import org.springframework.test.context.ContextConfiguration;
    import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
    import org.springframework.test.context.junit4.SpringRunner;
    
    @RunWith(SpringJUnit4ClassRunner.class)
    @ContextConfiguration({"classpath:applicationContext-redis.xml"})
    public class TestRedis {
    
        @Autowired
        private RedisTemplate redisTemplate;
    
        private static final Logger log  = Logger.getLogger(TestRedis.class.getName());
    
        @Test
        public void test(){
            redisTemplate.opsForValue().set("username", "熊二");
            log.info("value："+redisTemplate.opsForValue().get("username"));
        }
    }
