How to use Spring cache Manager with redis 1.6.2.RELEASE

We are using Spring Cache Manager with spring-data-redis 1.5.2. These days we want to upgrade spring-data-redis to latest release i.e:1.6.2.RELEASE.

For some weird reason everything works good with 1.5.2 but when upgrading to 1.6.2 we get

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'cacheManager' defined in ServletContext resource [/WEB-INF/spring-cache.xml]: Unsatisfied dependency expressed through constructor argument with index 0 of type [org.springframework.data.redis.core.RedisOperations]: Ambiguous constructor argument types - did you specify the correct bean references as constructor arguments?

This message seems like a mistake as redisTemplate is RedisTemplate which implements RedisOperations.

Any idea how to solve it?

P.S

note that when removing the cache configuration the 1.6.2 version seems to work good. So the issue is with the cache.

Configuration

web.xml

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
    /WEB-INF/spring-redis.xml
    /WEB-INF/spring-cache.xml 
    </param-value>
</context-param>

spring-redis.xml

<context:annotation-config />
    <bean class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration" />

    <bean
        class="org.springframework.security.web.session.HttpSessionEventPublisher" />

    <!-- end of seesion managment configuration -->

    <bean id="redisConnectionFactory"
        class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
        <property name="port" value="${app.redis.port}" />
        <property name="hostName" value="${app.redis.hostname}" />
        <property name="password" value="${app.redis.password}" />
        <property name="usePool" value="true" />
    </bean>

    <!-- for publishing string over redis channels -->
    <bean id="stringRedisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate">
        <property name="connectionFactory" ref="redisConnectionFactory" />
    </bean>

    <!-- for storing object into redis key,value -->
    <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
        <property name="connectionFactory" ref="redisConnectionFactory" />
    </bean>

spring-cache.xml

<!-- This file must load after spring-redis.xml -->
 <cache:annotation-driven /> 

<!-- declare Redis Cache Manager -->
<bean id="cacheManager" class="org.springframework.data.redis.cache.RedisCacheManager"
    c:template-ref="redisTemplate" />
</beans>

This is an old question, but for those who reach this page.

<bean id="cacheManager" class="org.springframework.data.redis.cache.RedisCacheManager" factory-method="create" c:connection-factory-ref="jedisConnectionFactory" p:transaction-aware="true" />

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

<bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory" p:host-name="${cache.redis.host}" p:port="${cache.redis.port}" p:use-pool="true">
  <constructor-arg ref="jedisPoolConfig"></constructor-arg>
</bean>

<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig" p:maxTotal="${cache.redis.pool.maxTotal}" p:maxIdle="${cache.redis.pool.maxIdle}" p:maxWaitMillis="${cache.redis.pool.maxWaitMillis}" p:testOnBorrow="true" />

While upgrading from Spring Data Redis 1.5.2.RELEASE to 1.6.2.RELEASE, we need to use the below config for RedisCacheManager. Previous releases were using redis-template-ref instead of redis-operations-ref. 

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

It seems the reason for this bug is that RedisCacheManager has two constructors. Both of them has RedisOperations as parameter. Forsome reason Spring couldnot understand its related to the first constructor and not to the second one. a work around is mention constructor-arg index

<bean id="cacheManager" class="org.springframework.data.redis.cache.RedisCacheManager">
        <constructor-arg index="0" ref="redisTemplate"></constructor-arg>
</bean>
