當我嘗試在 jboss 7.2 中部署我的 java 應用程序時，我遇到了鏈接錯誤

Question

我在 jboss 中部署的模塊依賴於 org.springframework:spring-orm:4.3.16.Release。 我沒有看到任何重復的依賴項添加到類路徑中。 根據我理解的例外情況，我的應用程序使用一個版本成功編譯，並且在部署期間它引用了另一個版本。 但我在任何地方都看不到任何重復的版本。

任何人都可以在這里幫助我解決問題嗎？ 請在下面找到詳細的例外情況。

Answer 1

java.lang.LinkageError當 class 由多個類加載器加載並且這些類在同一代碼中一起使用時發生。

在您的情況下，檢查您的應用程序是否打包了任何包含 JDK 或 J2EE API 類的 jars 並將它們刪除。
