执行结果：

 

action.path==/test
action.class==com.mystruts.demo.LoginAction
forward.name==success
forward.url==hello.jsp
forward.name==fail
forward.url==fail.jsp
action.path==/user
action.class==com.mystruts.demo.UserAction
forward.name==success
forward.url==list.jsp
forward.name==fail
forward.url==fail.jsp
