java - weblogic启动时发生LinkageError

Question

当我将 ear 项目部署到 weblogic 中时，在应用程序启动期间，LinkageError 显示如下:

weblogic的版本是10.3.6.0

Answer 1

此冲突可能是因为您的应用程序之一在其中一个 jar 中有一个类 (org/springframework/core/io/ResourceLoader)，该类与 weblogic 的嵌入 jar 之一 ( http://www.findjar.com/class/org/springframework/core/io/ResourceLoader.html ) 和相同的类冲突名称。
