spring+redis缓存服务器读取不到数据

根据key查出来的数据一直为null，很费解，因为我自己在集成之前写的测试的例子是可以访问的。所以经过分析，原来是value值没有序列化

只需要加上下面的配置就可以了

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

<beans:property name="valueSerializer" ref="jdkSerializationRedisSerializer" />

<beans:bean id="redisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"
                p:hostName="${redis.host}" p:port="${redis.port}"
                p:poolConfig-ref="redisPoolConfig" />
    <beans:bean id="stringSerializer" class="org.springframework.data.redis.serializer.StringRedisSerializer"/>
    <beans:bean id="jdkSerializationRedisSerializer" class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer"/>
    <!-- 开启事务，可以通过transcational注解控制 -->
    <beans:bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
        <beans:property name="connectionFactory" ref="redisConnectionFactory" />
        <beans:property name="keySerializer" ref="stringSerializer" />
        <beans:property name="valueSerializer" ref="jdkSerializationRedisSerializer" />
        <beans:property name="enableTransactionSupport" value="true" />
    </beans:bean>
    <!--redis end-->
