Java Spring和Hibernate第二级，使用Ehcache

我不知道为什么我的示例应用程序在第二个hibernate查询中不使用二级缓存

在日志中，我可以在查询后看到：

04-02-2014 08:28:10,869 PM DEBUG TwoPhaseLoad:194 - Adding entity to second-level cache: [com.pjcom.pjcomspringehcache.model.entity.Actor#1]

但在下一个查询中，Hibernate重复该查询

我的应用程序实现：

您需要检查一些东西来实现这一点。
首先，什么是hibernate版本，您使用的是3.2或3.3
对于3.2及以下版本
真的
net.sf.ehcache.hibernate.EhCacheProvider
3.3及以上
真的
net.sf.ehcache.hibernate.EhCacheRegionFactory
您还可以启用查询缓存。为此，请在hbm.xml中配置它：
真的
另一种方法是：
sessionFactory.getCurrentSession（）.createQuery（“…”）.setCacheable（true.list（）；

似乎

actorService.getActorById

是通过自定义查询实现的，而不是使用

entityManager.find（1，Actor.class）

或

session.load（Actor.class，1）

查询缓存已关闭，这意味着不会缓存此类查询的结果

自定义查询不会直接触发二级缓存。它们将首先命中查询缓存或数据库，返回的ID用于命中第二级缓存

为了解决这个问题，您可以使用这两种方法中的一种实现

actorService.getActorById

，这两种方法会命中二级缓存。或打开查询缓存：

 <prop key="hibernate.cache.use_query_cache">true</prop>

---

没有多少情况下我们真的希望使用这两个缓存中的一个，大多数情况下它们是同时使用的。

我已经发布了一个可能的回复，如果它不起作用，你能发布一个带有

hibernate.cache.use_sql\u comments=true

的日志吗？看看这篇我写的关于二级陷阱和查询缓存的文章，你的文章对我来说非常完美，我从中学到了很多。非常感谢。

You need to check few things to implement this.

Firstly, what is the hibernate version, you are using 3.2 or 3.3

For 3.2 and below
<property key="hibernate.cache.use_second_level_cache">true</property>
<property name="hibernate.cache.region.provider_class">net.sf.ehcache.hibernate.EhCacheProvider</property>

For 3.3 and above
<property key="hibernate.cache.use_second_level_cache">true</property>
<property name="hibernate.cache.region.factory_class">net.sf.ehcache.hibernate.EhCacheRegionFactory</property>


You can also enable query caching. To do so configure it in your hbm.xml:
<property key="hibernate.cache.use_query_cache">true</property>

Other way to do this is:
sessionFactory.getCurrentSession().createQuery("...").setCacheable(true).list();

 <prop key="hibernate.cache.use_query_cache">true</prop>

@NamedQuery(name="account.queryName",
   query="select acct from Account ...",
   hints={
       @QueryHint(name="org.hibernate.cacheable",
       value="true")
   }     
})
