Spring Cache注解+Redis（二）

之前有写过一篇Spring Cache注解+Redis

今天对Cache+Redis配置的优化。

首页还是Jar的依赖，请看之前的文章，这里不做赘述。

然后后XML的配置：

<?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"xmlns:cache="http://www.springframework.org/schema/cache"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache.xsd"default-autowire="byName"><context:property-placeholderlocation="classpath*:config/redis.properties" ignore-unresolvable="true"/><!-- 启用缓存注解功能 --><cache:annotation-driven cache-manager="cacheManager"/><!--Redis Cache 配置--><bean id="cacheManager" class="org.springframework.data.redis.cache.RedisCacheManager"><constructor-arg name="redisOperations" ref="redisTemplate"/></bean><!-- 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="${redis.testOnBorrow}"/></bean><bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"><property name="poolConfig" ref="poolConfig"/><property name="port" value="${redis.port}"/><property name="hostName" value="${redis.host}"/><property name="timeout" value="${redis.timeout}"/><property name="password" value="${redis.pwd}"/><property name="database" value="${redis.database}"/></bean><bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate"><property name="connectionFactory" ref="jedisConnectionFactory"/><!--<property name="defaultSerializer" ref="stringRedisSerializer"/>--><property name="keySerializer" ref="stringRedisSerializer"/><!--<property name="valueSerializer" ref="stringRedisSerializer"/>--><property name="hashKeySerializer" ref="stringRedisSerializer"/><!--<property name="hashValueSerializer" ref="stringRedisSerializer"/>--></bean><bean id="stringRedisSerializer" class="org.springframework.data.redis.serializer.StringRedisSerializer"/></beans>

 redis.properties请看上一篇文章；

缓存注解使用：

在service实现方法上加注解

    @Override@Cacheable(value = "ShardingTableCache", key = "'shardingTableName:' + #appId + ':' + #appUserId")public Integer getShardingTableName(String appId, String appUserId) {return mapper.getShardingTableName(appId, appUserId);}@Override@CacheEvict(value = "ShardingTableCache", key = "'shardingTableName:' + #appId + ':' + #appUserId")public int updateShardingTable(String appId, String appUserId, int shardingTable) {return mapper.updateShardingTable(appId, appUserId, shardingTable);}

使用redis客户端RedisDesktopManager查看效果如下图：

中间遇到的问题： 插入的hash类型的key前面会有一堆的\xac\xed\x00\x05t\x00\tb 这种东西

处理方法：redisTemplate中添加<property name="keySerializer" ref="stringRedisSerializer"/>等
