原因：无法加载 bean：类型：class:com.opensymphony.xwork2.ObjectFactory - bean - jar:file:/C:/adarsh/Struts/.metadata/.plugins/org.eclipse.wst.server.core/ tmp0/wtpwebapps/Struts2Starter/WEB-INF/lib/ struts2-core-2.3.4.1.jar !/struts-default.xml:29:72

原因：名称为 xwork 的 bean 类型类 com.opensymphony.xwork2.ObjectFactory 已被 bean - jar:file:/C:/adarsh/Struts/.metadata/.plugins/org.eclipse.wst.server 加载。 core/tmp0/wtpwebapps/Struts2Starter/WEB-INF/lib/ struts2-core-2.3.1.2.jar !/struts-default.xml:29:72 - bean - jar:file:/C:/adarsh/Struts/。 metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/Struts2Starter/WEB-INF/lib/ struts2-core-2.3.4.1.jar !/struts-default.xml:29:72

您只需在项目中拥有多个版本的 Struts2 库。

删除除您要使用的版本之外的所有其他版本，您会没事的。

您的 WEB-INF\classes 文件夹可能包含一个 struts.xml 并且 eclipse 在您的 classess\struts.xml 加载后加载了它的 struts.xml 两次。尝试清理您的 classes 文件夹，或者至少删除那里的 struts.xml 文件。
