BeanAlreadyExistsException - Oracle WebLogic

问题描述 投票：0回答：4

我在 Web 服务器上部署了一个应用程序，现在我尝试在 Web 服务器上部署另一个应用程序，但收到 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，我从服务器中删除了第一个项目 - 然而这不起作用 - 在部署第二个应用程序时我仍然遇到了此异常。

这是堆栈跟踪：

您可以尝试从 /base_domain/config/config.xml 中删除“app-deployment”部分，其中包含ear/war **

打开 weblogic.xml 文件。并查看 library-ref 标签。最有可能的是对 webapp.encoding.default 的重复引用（这是您的日志中提到的库）

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

adf.oracle.domain

  1. cd $DOMAIN_HOME
  2. cd config/jdbc
  3. 删除config的xml文件
  4. 重启服务器
