很简单的SSH整合，可我访问页面总报404，请高手帮忙
这是我的源码
dao文件是直接用myeclipse生成的文件


service文件源码
public class UserService {
private UserDAO userDAO;

public User regist(User user){

userDAO.save(user);
return user;
}

public UserDAO getUserDAO() {
return userDAO;
}

public void setUserDAO(UserDAO userDAO) {
this.userDAO = userDAO;
}
}


这是struts文件的Action类private UserService userService;

public UserService getUserService() {
return userService;
}

public void setUserService(UserService userService) {
this.userService = userService;
}

public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
UserForm userForm = (UserForm) form;// TODO Auto-generated method stub
User user = new User();
user.setUsername(userForm.getUsername());
user.setPassword(userForm.getPassword());
user.setEmail(userForm.getEmail());
if(userService.regist(user) != null){
return mapping.findForward("success");
}else{
ActionErrors errors = new ActionErrors();
errors.add("username",new ActionError("errors.username_is_used"));
saveErrors(request, errors);
userForm.setPassword("");
userForm.setPassword2("");
return mapping.findForward("failure");
}

}


vo文件也是直接映射出来的没有改动



这是applicationContext.xml文件
