是否可以使用带有Redis的Spring缓存抽象来创建多个缓存存储区? [英] Is it possible to create multiple cache stores using Spring's cache abstraction with redis?

问题描述

我正在使用Spring MVC开发一个Web应用程序，并且正在使用带有Redis的spring缓存抽象来缓存我的数据库查询.但是我无法使用@Cacheable创建多个缓存存储.

I'm developing a web application using Spring MVC and I'm using using spring's cache abstraction with Redis to cache my database queries. But I am not able to create multiple cache stores using @Cacheable.

@Cacheable("acache")
public String atest(int i) {
   return "a";
}

@Cacheable("bcache")
public String btest(int i) {
   return "b";
}

...
...
String s = atest(1);
String r = btest(1);

使用redis，s和r都具有相同的值"a".即使我将这两种方法都缓存在不同的缓存中，它似乎也没有作用.

Using redis, both s and r have the same value "a". Even though I cache the two methods in different caches, it seems to have no effect.

但是当我使用Spring的SimpleCacheManager时，这可以很好地工作.

But this works fine when I use Spring's SimpleCacheManager.

Redis的Spring bean配置:

Spring bean configuration for Redis:

<cache:annotation-driven />

<bean id="jedisConnectionFactory"
        class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"
        p:hostName="${redis.host-name}"
        p:port="${redis.port}"
        p:usePool="true"/>


<bean id="redisTemplate"
        class="org.springframework.data.redis.core.RedisTemplate"
        p:connectionFactory-ref="jedisConnectionFactory"/>

<bean id="cacheManager"
        class="org.springframework.data.redis.cache.RedisCacheManager"
        c:template-ref="redisTemplate">
</bean>

推荐答案

根据文档，RedisCacheManager默认情况下直接保存键，而不附加前缀(缓存名称，用作名称空间).要更改它并避免冲突，请将'usePrefix'设置为'true':

According to the docs the RedisCacheManager by default saves the keys directly, without appending a prefix (cache name, which acts as a namespace). To change it and avoid clashes set 'usePrefix' to 'true': http://static.springsource.org/spring-data/data-redis/docs/current/api/org/springframework/data/redis/cache/RedisCacheManager.html
