前言：
本文项目都是依赖spring环境，且本文在本机启动了redis环境
spring-data-redis就是对jedis的API封装,提供了RedisTemplate对象进行缓存操作
1）引入redis的Jar
<!-- 缓存 -->
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.8.1</version>
</dependency>
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-redis</artifactId>
<version>1.7.2.RELEASE</version>
</dependency>
2)配置文件redis-config.properties
# Redis settings
# server IP
redis.host=127.0.0.1
redis.port=6379
redis.pass=
redis.database=0
redis.maxIdle=300
redis.maxWait=3000
redis.testOnBorrow=true
3）spring-data-redis配置文件：
<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>
4）依赖注入RedisTemplate对象
@Autowired
private RedisTemplate redisTemplate;
