UserLogin.java

package com.xp.web;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@RequestMapping("/user")
public class UserLogin {
    
    @RequestMapping("/login")
    public String login() {
        System.out.println("=======");
        return "login";
    }

}

 
访问：http://localhost:8089/user/login.do，没异常，也没报错，是不是还缺配置项？
