找了半天， 原来在这可以配置它的序列化方式

valueSerializer 对应opsForValue

hashValueSerializer 对应 HashOperations

JDK的如下

<bean id="creditRedisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate">

<property name="connectionFactory" ref="jedisConnectionFactory" />

<property name="valueSerializer">

<bean

class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer" />

</property>

<property name="hashValueSerializer">

<bean

class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer" />

</property>

</bean>
