看上去很吓人,实际上是因为tomcat中对应工程下的lib中的jar包出现重复,其实当你在工程中的lib导入jar包后,tomcat容器中对应工程也会有jar包的副本,但是当你删除掉原工程内的jar包后却仍然会在tomcat中保留jar,因此会出现struts的jar包冲突(即Caused by: Bean type classcom.opensymphony.xwork2.ObjectFactory with the name xwork has already beenloaded by bean - jar),所以才会出现上述错误,故只要删除掉tomcat项目中的jar包再重新发布即可。
