Java BeanReadyExistsException-Oracle WebLogic

我在我的web服务器上部署了一个应用程序，现在我正在尝试在web服务器上部署另一个应用程序，我得到了BeanAlreadyExistsException。我想这可能是因为我在两个不同的项目中有两个同名的bean。因此，我从服务器上删除了第一个项目-但是这不起作用-我在部署第二个应用程序时仍然遇到了这个异常

以下是堆栈跟踪：

####
####只需从weblogic-application.xml文件中删除多个库引用即可

adf.oracle.domain

cd$DOMAIN\u HOME
cd-config/jdbc
删除到配置的xml文件
重新启动服务器
您可以尝试从/base\u domain/config/config.xml中删除“应用程序部署”部分，该部分包含ear/war
**

**
打开youuweblogic.xml文件，并查看库参考标签。很可能存在对webapp.encoding.default的重复引用（这是日志中提到的库）
能否粘贴weblogic-application.xml此错误通常表示某些元素重复。在本例中，元素的值为-webapp.encoding.defaultMy experience：该消息来自weblogic使用的Spring IOC：这意味着“bean”不是您的（企业）Java bean，因此在该级别上不会有任何冲突。这个错误指的是容器资源（或对它们的引用），如数据源、jms或javamail会话或应用程序本身，正如Andrea所说。这些听起来像是你的描述符试图创建一个已经存在的资源对象……你能进一步解释一下吗？请不要像这样发布答案，因为这是一个注释。如果你继续这样做，你将无法在SO中提问，因为你将收到反对票。所以，请阅读，我试图帮助你不要成为rood。这是一个评论，你应该把它放在主要问题下的评论下。阅读以理解如何正确回答。有句谚语说，永远不要免费做事情，告诉人们如何评论，在哪里做才是你得到报酬的，然后继续做下去，老兄，你仍然不是最好的。
