SpringDataRedis1.7.2 Redis，注入RedisOperations而不是RedisTemplate

Question

我在将Spring 1.5.2. Redis 1.7.2.RELEASE，迁移到RedisCacheManager时遇到了问题，RedisCacheManager在1.5.2中使用了RedisTemplate，在1.7.2中使用了Redis和RedisOperations作为构造函数参数。下面是我当前的Spring配置( 1.5.2.RELEASE )。如何将其配置为1.7.2.RELEASE？

<cache:annotation-driven cache-manager="cacheManager" />

    <!-- Redis Connection Factory -->
    <beans:bean id="jedisConnectionFactory"
        class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"
        p:host-name="${redis.host-name}" p:port="${redis.port}" p:use-pool="true" />

    <!-- Redis Template Definition -->
    <beans:bean id="redisTemplate"
        class="org.springframework.data.redis.core.RedisTemplate"
        p:connection-factory-ref="jedisConnectionFactory" p:keySerializer-ref="stringRedisSerializer"
        p:hashKeySerializer-ref="stringRedisSerializer" />

    <beans:bean id="stringRedisSerializer"
        class="org.springframework.data.redis.serializer.StringRedisSerializer" />

    <!-- declare Redis Cache Manager -->
    <beans:bean id='cacheManager'
        class='org.springframework.data.redis.cache.RedisCacheManager'
        c:template-ref='redisTemplate'>
        <beans:property name="expires">
            <beans:map>
                <beans:entry key="sessionData" value="7200"></beans:entry>
                <beans:entry key="portalData" value="7200"></beans:entry>
                <beans:entry key="referenceData" value="86400"></beans:entry>
            </beans:map>
        </beans:property>
    </beans:bean> 

如果我按照以下方式为RedisOperations声明一个bean并按如下方式将其注入RedisCacheManager中呢？

<beans:bean id="**redisOperations**"
        class="org.springframework.data.redis.core.RedisOperations"/>

<!-- declare Redis Cache Manager -->
        <beans:bean id='cacheManager'
            class='org.springframework.data.redis.cache.RedisCacheManager'
            c:template-ref='**redisOperations**'>
            <beans:property name="expires">
                <beans:map>
                    <beans:entry key="sessionData" value="7200"></beans:entry>
                    <beans:entry key="portalData" value="7200"></beans:entry>
                    <beans:entry key="referenceData" value="86400"></beans:entry>
                </beans:map>
            </beans:property>
        </beans:bean>

RedisCacheManager已更改为在1.7.2中使用RedisOperations，而不是在1.5.2.RELEASE中使用RedisTemplate。

https://github.com/spring-projects/spring-data-redis/blob/1.7.2.RELEASE/src/main/java/org/springframework/data/redis/cache/RedisCacheManager.java

https://github.com/spring-projects/spring-data-redis/blob/1.5.2.RELEASE/src/main/java/org/springframework/data/redis/cache/RedisCacheManager.java

正因为如此，上述redis配置将我抛到错误下面。

我正在使用SpringVersion4.3.2.RELEASE和Spring 1.7.2.RELEASE。请对这个注入问题和如何解决它有您的建议。我不想在我的应用程序中使用集群设置。

这应该能行。您只需使用正确的构造函数名称空间即可。

<beans:bean id='cacheManager'
        class='org.springframework.data.redis.cache.RedisCacheManager'
        c:redis-operations-ref='redisTemplate'>
        <beans:property name="expires">
            <beans:map>
                <beans:entry key="sessionData" value="7200"></beans:entry>
                <beans:entry key="portalData" value="7200"></beans:entry>
                <beans:entry key="referenceData" value="86400"></beans:entry>
            </beans:map>
        </beans:property>
</beans:bean>
