开放自由和休眠 [英] Open liberty and Hibernate

问题描述

我可以在开放自由中使用Hibernate作为JPA实现吗?如果存在这样的集成，我想它会带有分布式缓存和JTA吗?

Can I use Hibernate as JPA implementation in open-liberty? If such integration exists, I would presume that it comes with distributed caching and JTA?

推荐答案

是的，在OpenLiberty中，我们具有jpaContainer-2.1功能，该功能仅提供 JPA容器集成代码，并允许用户插入他们自己的符合JPA 2.1的实现(即EclipseLink或Hibernate).

Yes, in OpenLiberty we have the jpaContainer-2.1 feature, which provides only the JPA container integration code, and allows the user to plug in their own JPA 2.1 compliant implementation (i.e. EclipseLink or Hibernate).

专门用于Hibernate，jpaContainer-2.1功能将把Hibernate与Liberty的事务管理器集成在一起.参见

Specifically for Hibernate, the jpaContainer-2.1 feature will integrate Hibernate with Liberty's transaction manager. See LibertyJtaPlatform

您可以在此处找到完整的文档，包括配置示例:
部署JPA申请自由

You can find full documentation here, including config examples:
Deploying a JPA application to Liberty

在server.xml中需要的基本配置如下:

The basic config you will need in server.xml is the following:

<featureManager>
   <feature>jpaContainer-2.1</feature>
   <feature>bells-1.0</feature>
      ...    
</featureManager>    

<!-- Making a 'bell' for the library will register any META-INF/services in the referenced library with the Liberty runtime -->
<bell libraryRef="hibernate"/>

<!-- Include all of the hibernate jars in a shared lib -->
<library id="hibernate">
    <fileset dir="${server.config.dir}/hibernate/" includes="*.jar"/>
</library>

<!-- OPTIONAL: If you wish to directly reference hibernate APIs in your app, you will need to configure a shared library classloader -->
<application location="myApp.war">
   <classloader commonLibraryRef="hibernate"/>
</application>
