java - springmvc 无法扫描到controller层

问题描述

各种404，请求/user/showUser不能进入controller，整了一天，快疯了，求组各位大神！直接上代码项目结构：

controller

package com.chs.controller;import java.util.Map;import javax.annotation.Resource; import javax.servlet.http.HttpServletRequest; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping;import com.chs.base.util.ReflectionUtil;import com.chs.model.User;import com.chs.service.IUserService; @Controller @RequestMapping('/user') public class UserController { @Resource private IUserService userService;@RequestMapping('/showUser') public String toIndex(HttpServletRequest request,Model model){ System.out.println('------------------------'); Map<String, Object> paramMap = ReflectionUtil.po2Map(request); User user = this.userService.getUserById(paramMap); return 'showUser'; } }

问题解答

会不会是jsp里的请求路径问题，建议试下改成绝对路径试下
