通过以上教程将Redis的环境搭建起来后，使用SpringDataRedis在Java中对Redis进行操作。
SpringDataRedis
SpringDataRedis是spring大家族中的一部分,提供了在spring应用中通过简单的配置访问redis服务,对redis底层开发包(Jedis,JRedis,andRJC)进行了高度封装,RedisTemplate提供了redis各种操作,异常处理及序列化,支持发布订阅
SpringDataRedis针对Jedis提供了如下功能:
1.连接池自动管理,提供了一个高度封装的RedisTemplate类
2.针对Jedis客户端中大量api进行了归类封装,将同一类型操作封装为operation接口
ValueIoerations:简单K-V操作
SetIOperations:set类型数据操作.
ZSetOperations:zset类型数据操作
HashOperations:针对map类型的数据操作
ListOperations:针对list类型的数据操作.
实现
打开IDEA新建project-Maven Project
依次输入坐标，建成后目录
然后打开pom.xml，添加spring和jedis以及junit的依赖
<?xml version="1.0" encoding="UTF-8"?>

</build>
</project>
然后在src/main/resources下创建properties文件夹,然后新建文件redis-config.properties
在此属性文件中配置redis连接的ip和端口等信息
# Redis settings # server IP redis.host=192.168.40.133 # server port redis.port=6379 # server pass redis.pass= # use dbIndex redis.database=0 # 最大空闲数 redis.maxIdle=300 #连接时的最大等待数 redis.maxWait=3000 #在提取一个jedis实例时，是否提前进行验证操作；如果为true，则得到的jedis实例均是可用的； redis.testOnBorrow=true
同理再在src/main/resources下创建spring文件夹,然后新建文件applicationContext-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"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:cache="http://www.springframework.org/schema/cache"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/cache
http://www.springframework.org/schema/cache/spring-cache.xsd
http://www.springframework.org/schema/mvc ">
<context:property-placeholder location="classpath*:properties/*.properties"/>
<!-- redis 相关配置 -->
<bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig">
<property name="maxIdle" value="${redis.maxIdle}"/>
<property name="maxWaitMillis" value="${redis.maxWait}"/>
<property name="testOnBorrow" value="${redis.testOnBorrow}"/>
</bean>
<bean id="JedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"
p:host-name="${redis.host}" p:port="${redis.port}" p:password="${redis.pass}" p:pool-config-ref="poolConfig"/>
<bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
<property name="connectionFactory" ref="JedisConnectionFactory"/>
</bean>
</beans>
然后在src/main下新建包，包中新建类，开启Redis服务端后进行测试存取值
package com.badao.test;
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;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:spring/applicationContext-redis.xml")
public class SpringDataRedisTest {
@Autowired
private RedisTemplate redisTemplate;
@Test
public void setValue(){
redisTemplate.boundValueOps("name").set("badao");
}
@Test
public void getValue(){
String str = (String) redisTemplate.boundValueOps("name").get();
System.out.println(str);
}
}
运行单元测试方法，先存值再取值结果
