Maven打开JPA插件增强：似乎工作，但它并没有增强我的实体

当我编译我的Maven项目时，它说我的实体是增强的。但是，当我通过EntityManagerFactory启动数据库连接时，此处的代码发生错误：em = factory.createEntityManager（）;我相信我遵循了网络中的所有步骤......但是我遇到了这个错误。请帮助..有关这方面的任何建议？非常感谢你。Maven打开JPA插件增强：似乎工作，但它并没有增强我的实体

错误导致错误的代码部分。

factory = Persistence.createEntityManagerFactory("LotMovementPU"); 
     em = factory.createEntityManager();

Tihs是编译时的日志。

在此建设的ANT风格，这就是在build.xml发现也许我的增强都没有后编译增强它？如果是的话，你如何在maven中进行后期编译增强？

build.xml增强ant中的实体。

     <!-- Empty placeholder for easier customization. --> 
     <!-- You can override this target in the ../build.xml file. --> 

      <echo message="begin openJPAC"/> 
     <path id="openjpa.path.id">   
      <pathelement location="${build.classes.dir}"/> 

      <!-- Adding the OpenJPA jars into the classpath --> 
      <fileset dir="D:\openjpa\apache-openjpa-2.2.0\" includes="*.jar"/> 
      <!-- or if you create a OpenJPA Library you can use that instead --> 
      <!--<pathelement path="${libs.OpenJPA.classpath}"/>--> 
     </path> 

     <taskdef name="openjpac" classname="org.apache.openjpa.ant.PCEnhancerTask">

我找到了解决方案。我删除了插件“openjpa-maven-plugin”，并用POM.XML - Plugin元素替换它（请参阅下面的插件）。当你编译它时，你会在下面看到这条消息。请参阅编译消息。顺便说一句，我使用Netbeans 7.2.1，Maven和struts2-spring插件。

编译消息。 [antrun：run] 执行任务 [java] 63 LotMovementPU INFO [main] openjpa.Tool - 在类型“lotmovement.business.entity.UserProfile”上运行的增强器。执行的任务
