Weblogic部署导致 - 创建名为'org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor＃0'的bean时出错

Question

我正在使用Hibernate 4，Spring 3，JSF 2.0和Weblogic 10.3.6

当我启动weblogic服务器和服务器成功启动时，无论何时开始发布应用程序，我都会收到以下异常。

   Error creating bean with name 
 'org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor#0' 
  defined in ServletContext resource [/WEB-INF/applicationContext.xml]: 
  Initialization of bean failed; nested exception is 
  org.springframework.beans.factory.BeanCreationException: 

    Caused By: org.springframework.beans.factory.BeanCreationException: Error creating

我在applicationContext.xml

在Weblogic 10.3.6中，我通过在commEnv.cmd

中添加以下内容来启用JPA2支持

@rem Enable JPA 2.0 functionality on WebLogic Server 
set PRE_CLASSPATH=%BEA_HOME%\modules\javax.persistence_1.1.0.0_2-0.jar;
%BEA_HOME%\modules\com.oracle.jpa2support_1.0.0.0_2-1.jar

如何解决此错误？

Answer 1

此问题已得到解决，因为Weblogic 10.3.6 exe分发没有javax.persistence_1.0.0.0_2-0-0.jar，它的内容是javax.persistence_1.1.0.0_2-0.jar。

该类和jpa2support_1.0.0.0_2-0.jar一起需要在类路径中。

由于

Answer 2

问题可能与类加载层次结构有关，而某些类是从系统类加载器而不是EAR中包含的jar加载的。

在 WebLogic 服务器中，系统类路径中存在的任何.jar文件都由WebLogic Server 系统类加载器加载。在服务器实例中运行的所有应用程序都加载到应用程序类加载器中，这些类加载器是系统类加载器的子代。在系统类加载器的此实现中，应用程序不能使用已存在于系统类加载器中的不同版本的第三方jar。每个子类加载器都会向父（系统类加载器）询问特定的类，并且不能加载父类看到的类。

例如，如果$ CLASSPATH和应用程序EAR中都存在一个名为com.foo.Baz的类，则加载$ CLASSPATH中的类，而不是EAR中的类。由于weblogic.jar位于$ CLASSPATH中，因此应用程序无法覆盖任何WebLogic Server类。

FilteringClassLoader 提供了一种机制，您可以配置部署描述符以明确指定应始终从应用程序加载某些包，而不是由系统类加载器加载。

FilteringClassLoader 位于应用程序类加载器和系统之间。它是系统类加载器的子项，也是应用程序类加载器的父项。 FilteringClassLoader拦截loadClass（String className）方法，并将className与 weblogic-application.xml 文件中指定的包列表进行比较。

总之，您是否会尝试修改weblogic-application.xml，以便从EAR中包含的jar中加载一些包而不是系统类加载器？示例如下：

<prefer-application-packages>
    <package-name>antlr.*</package-name>
    <package-name>org.apache.commons.*</package-name>
    <package-name>org.apache.xmlbeans.*</package-name>
    <package-name>org.springframework.*</package-name>
    <package-name>org.hibernate.*</package-name>
    <package-name>javax.persistence.*</package-name>
</prefer-application-packages>
