缓存默认的Spring Data JPA方法 [英] Caching of default Spring Data JPA Methods

问题描述

任务:使spring jpa数据的基本方法可缓存(使用hibernate/jpa)，例如

Task: make basic methods of spring jpa data cacheable (using hibernate/jpa), like

Page<T> findAll(Pageable pageable)
List<T> findAll();
etc

并在某种顶级通用接口级别上执行此操作，而无需自定义dao实现.

and do it on some kind of top generic interface level, without custom dao implementations.

这是原始主题的延续 如何在默认Spring Data JPA方法上添加QueryHint? /a>

This is continuation of original topic How to add QueryHints on Default Spring Data JPA Methods?

我还没有找到解决方案，但是尝试以不同的方式解决它，包括添加注释，例如 @javax.persistence.Cacheable和@org.hibernate.annotations.Cache 在数据模型类上.

I haven't still found the solution, but tried to solve it with different ways, including adding annotations like @javax.persistence.Cacheable and @org.hibernate.annotations.Cache on data model class.

以下是我的配置摘录:

1. pom.xml(摘自

2. applicationContext.xml:

3. applicationContext.xml:

   <tx:annotation-driven mode="aspectj" transaction-manager="transactionManager"/>
   <bean class="org.springframework.orm.jpa.JpaTransactionManager" id="transactionManager">
       <property name="entityManagerFactory" ref="entityManagerFactory"/>
   </bean>     
   <bean class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" id="entityManagerFactory">
       <property name="persistenceUnitName" value="persistenceUnit"/>
       <property name="dataSource" ref="dataSource"/>
   </bean>
   

4. persistence.xml:

5. persistence.xml:

   ...
   <provider>org.hibernate.ejb.HibernatePersistence</provider>
   <shared-cache-mode>ENABLE_SELECTIVE</shared-cache-mode>
   <properties>
       ...
       <property name="hibernate.cache.region.factory_class" value="org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory"/>
       <property name="hibernate.cache.use_second_level_cache" value="true"/>
       <property name="hibernate.cache.use_query_cache" value="true" />
   </properties>
   ...
   

6. 除了上述所有内容之外，我还配置了spring 3.2缓存，但最终我希望有一个不基于spring缓存的解决方案，因此目前我不使用spring缓存配置.

7. Apart from all above I have configured spring 3.2 cache, but eventually I want to have a solution not based on spring cache, so at the moment I don't use spring cache config.

   我的模型如下:

   @Entity
   @Table(name = "ABC")
   @Cacheable(true)
   @Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
   public class ABC {
   ...
   

8. 我的父类通用DAO如下:

9. My parent generic DAO looks like:

   public interface CacheableGenericDao<T, ID> extends JpaRepository<T, ID>, JpaSpecificationExecutor<T> {
       List<T> findAll();
       Page<T> findAll(Pageable pageable);
       <S extends T> S save(S entity);
       ...

P.S.这是关于该主题的另一个有用的链接，但我确实想使用基本方法名称.

P.S. Here is one more useful link concerning the topic, but I do want use basic method names.

那么我在概念上想念什么?有什么办法吗?还是我想要太多?

So what am I missing conceptually? Is there any approach at all or do I want too much?
