堆栈跟踪中提到了您的问题:
Caused by: Bean type class com.opensymphony.xwork2.ObjectFactory with the name xwork has
already been loaded by bean - jar:file:/F:/m/.metadata/.me_tcat/webapps/project/WEB-INF
/lib/struts2-core-2.1.8.1.jar!/struts-default.xml:29:72 - bean - jar:file:/F:/m/.metadata
/.me_tcat/webapps/project/WEB-INF/lib/struts2-core-2.2.3.jar!/struts-default.xml:29:72
似乎在
WEB-INF/lib
目录中有多个struts2 core-*.jar
。我想你应该只有一个。清理一下。还要查看您的.classpath
是否没有重复的条目。错误是直接的:
类com.opensymphony.xwork2.ObjectFactory,名称为xwork
已由bean加载
您是否已将struts2-core-X.X.X.X.jar添加到服务器类路径中?以及项目构建路径
如果是,则移除。它会起作用。这是一个jar问题。您需要下载所有最新的struts JAR 尝试以下jar库:
- common-chain-12.jar
- common-fileupload-1.3.1.jar
- commons-io-2.2.jar
- commons-logging-api-1.1.jar
尤其要确保xwork和struts2 core JAR的版本相同。Java 8之后,这些jar不再是可选的。完全正确,重复的jar导致了同样的问题!,谢谢
