Redis

Spring使用Redis;

加入redis依赖

<!-- 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>  

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>

 

实现类中注入依赖

@Autowired
private RedisTemplate redisTemplate;

redisTemplate.boundValueOps操作k-v

redisTemplate.boundSetOps操作Set

redisTemplate.boundListOps操作List

redisTemplate.boundHashOps操作Hash(Map)

步骤:

1.先从缓存中查询,如果为空则去数据库中查询,再存放在redis中

2.在增删改的操作中,删除缓存,清楚缓存。避免数据有变化时,只查询之前缓存的数据;
