我在我的Web服務器上部署了一個應用程序，現在我試圖在Web服務器上隱藏另一個應用程序，並收到BeanAlreadyExistsException。我認爲這可能是由於我在兩個不同的項目中有兩個同名的bean。所以我從服務器中刪除了第一個項目 - 但是沒有奏效 - 在部署第二個應用程序時，我仍然得到了這個異常。BeanAlreadyExistsException - Oracle WebLogic
這裏是堆棧跟蹤：

可以粘貼您的weblogic-application.xml中這個錯誤通常表示某些元素的重複。在這種情況下，帶有值的元素 - webapp.encoding.default –
prash
我的經驗：該消息來自weblogic使用的Spring IOC：這意味着「Bean」不是您的（Enterprise）Java Bean，因此不能在該級別發生任何碰撞。錯誤指的是容器資源（或對它們的引用），如數據源，jms或javamail會話或應用程序itaself – Andrea
這就像安德烈所說的。這些聽起來像你的描述符試圖創建一個已經存在的資源對象... – megathor
