Question

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，我会假设它带有分布式缓存和JTA？

Answer 1

是的，在OpenLiberty中我们有jpaContainer-2.1功能，它只提供 JPA容器集成代码，并允许用户插入他们自己的JPA 2.1兼容实现（即EclipseLink或休眠）。

特别是对于Hibernate，jpaContainer-2.1功能将Hibernate与Liberty的事务管理器集成在一起。见LibertyJtaPlatform

您可以在此处找到完整的文档，包括配置示例：
Deploying a JPA application to Liberty

server.xml中需要的基本配置如下：

<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>
