Spring Data + Hibernate查询缓存不起作用

Spring Data + Hibernate查询缓存不起作用

<cache:annotation-driven />

中

jpa-context.xml

缺少，它可以解决问题。最终

jpa-context.xml

是

<?xml version="1.0" encoding="UTF-8"?><beans    xmlns:p="http://www.springframework.org/schema/p"     xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xmlns:cache="http://www.springframework.org/schema/cache"     xmlns:mvc="http://www.springframework.org/schema/mvc"    xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd          http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd        http://www.springframework.org/schema/cache        http://www.springframework.org/schema/cache/spring-cache.xsd"    default-autowire="byName">    <tx:annotation-driven />    <cache:annotation-driven />    <bean id="cacheManager" >      <property name="caches">         <set>          <bean  p:name="merchantServices"/>        </set>      </property>    </bean></beans>

我还补充说

resources/ehcache.xml

。

<?xml version="1.0" encoding="UTF-8"?><ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xsi:nonamespaceSchemaLocation="http://ehcache.org/ehcache.xsd"><diskStore path="/home/prayag/cache_"/><defaultCache        eternal="false"        maxElementsInMemory="1000"        overflowToDisk="true"        diskPersistent="true"        timeToLiveSeconds="300"        /></ehcache>

<propertyname="hibernate.cache.provider_configuration_file_resource_path">ehcache.xml</property>

在中被引用

resources/hibernate.cfg.xml

。

我的CPU缓存conf是
