Spring WebSphere加载时编织没有增强jpa实体

我已经用我的最新配置重新编写了我的整个问题。我已经改变和测试多次，仍然没有找到适当的解决方案

在我的项目中，我很难为jpa类增强启用加载时编织

我使用的是WebSphere8.5，它反过来又使用OpenJPA2.2.2。我有一个

Ear

文件和一个

War

文件，以及许多包含

JPA

实体和自定义命名的

persistence.xml

文件的依赖JAR

像这样：

MyApp.ear
|-- lib ## contains spring files and other shared libraries
|-- utilJars ## contains my custom made utility jars
|   |-- core.jar ## core-persistence.xml
|   |-- core-api.jar ## core entities
|   |-- mod1.jar ## mod1-persistence.xml
|   |-- mod1-api.jar ## mod1 entities
|   `-- control.jar ## depends on all above jars (in **`MANIFEST.MF`**), 
|                      `contains the main application context (`control-context.xml`) config shown below
`-- MyWeb.war

我在control.jar中的主上下文文件control-context.xml如下所示：

我的实体都有@Entity和适当的@Id标记，还有什么，它们以前一直作为实体工作，我没有修改它们，所以我确信我的实体是有效的

现在回答问题： 我在我的mod1 jar中设置了一个spring rest jpa资源库，它使用oneEMF：

<jpa:repositories base-package="com.example.myapp.mod1.model.repositories" entity-manager-factory-ref="oneEMF" />

当我在应用程序部署和启动后点击url时，我收到以下消息：

Error 500: org.springframework.web.util.NestedServletException: Request processing failed; 
`-- nested exception is org.springframework.orm.jpa.JpaSystemException: No registered metadata for type "class com.example.myapp.core.model.MyEntity". This can happen if this class has not been annotated as a persistent entity or specified in the persistence unit (ex: in the orm.xml). ;

错误500:org.springframework.web.util.NestedServletException:请求处理失败；
`--嵌套的异常是org.springframework.orm.jpa.JpaSystemException：类型“class com.example.myapp.core.model.MyEntity”没有注册元数据。如果这个类没有被注释为持久性实体或在持久性单元（例如：在orm.xml中）中指定，就会发生这种情况；

为什么我的实体在加载时没有增强？

我已经浪费了很多时间试图配置这个被认为是简单的设置，但是我不知道为什么我没有得到增强。任何帮助或同情都将不胜感激

更新：

在我的war classes文件夹的META-INF目录中放置一个伪persistence.xml已成功触发实体扫描，但从我所读到的内容来看，如果我在spring中使用packagesToScan，则不需要persistence.xml。此包扫描是否涉及将由加载时间编织器增强的实体

谢谢您的时间。

请发布com.example.mymodule.model.SomeEntity类。您是将OpenJPA JAR包含在应用程序中还是使用WebSphere附带的应用程序？请发布您的persistence.xml。如果我需要类路径中的OpenJPA，我可以从哪里获得它？我可以在WebSphere/AppServer/plugins中的plugins文件夹中看到jar。我是否需要手动将其放在我的ear或共享库中，或者是否有某种方式以更为网络化的方式引用它？您不需要openJPA JAR，它们是随WebSphere提供的，但是您需要persistence.xml才能由容器处理注释。Spring建议您可以构造一个没有persistence xml的持久化单元。您是说我还是需要一个持久化xml吗？如果您使用LocalContainerEntityManagerFactoryBean进行基于Spring的扫描，则不需要persistence.xml。您可以在配置中添加标签吗？
