@Results({@Result(name = "success", location = "/success.jsp"),
        @Result(name = "failure", location = "/failure.jsp")})
public class UserAction extends ActionSupport {
    @Resource
    private UserManager userManager;
    private User user;

    @Action(value = "addUser")

    public User getUser() {
        return user;
    }

    public void setUser(User user) {
        this.user = user;
    }

}

参考

主要是参考 基于注解的SSH将配置精简到极致
