原因是spring配置文件,开启了事务导致的,redis是缓存用的,不需要开启事务,正确的配置如下:
<!--redis操作模版,使用该对象可以操作redis --> <bean id="redisTemplateTax" class="org.springframework.data.redis.core.RedisTemplate" > <property name="connectionFactory" ref="connectionFactoryTax" /> <!--如果不配置Serializer,那么存储的时候缺省使用String,如果用User类型存储,那么会提示错误User can't cast to String!! --> <property name="keySerializer" > <bean class="org.springframework.data.redis.serializer.StringRedisSerializer" /> </property> <property name="valueSerializer" > <bean class="org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer" /> </property> <property name="hashKeySerializer"> <bean class="org.springframework.data.redis.serializer.StringRedisSerializer"/> </property> <property name="hashValueSerializer"> <bean class="org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer"/> </property> <!--开启事务 --> <property name="enableTransactionSupport" value="false"></property> </bean >
