web.xml中需要配置

創建控制器UserController

package com.li.test;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;

import org.apache.log4j.Logger;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import com.alibaba.fastjson.JSON;
import com.li.pojo.User;
import com.li.service.IUserService;
@Controller
@RequestMapping("/user")
public class UserController {

	@Resource
	private IUserService userService;
	private static Logger logger = Logger.getLogger(UserController.class);
	@RequestMapping("/showUser")
	public String showUser(HttpServletRequest request,Model model){
		int userId = Integer.parseInt(request.getParameter("id"));
		User user = userService.getUserId(userId);
		logger.info(JSON.toJSONString(user));
		model.addAttribute("user", user);
		return "showUser";
	}
}

在web-inf 下新建jsp文件夾 創建showUser.jsp

${user.name}

啓動項目在瀏覽器輸入http://127.0.0.1:8080/ssm/user/showUser.do?id=1

通過springMvc掃描控制器會發起對應方法，return 繼續在mvc中找到jsp頁面

{"age":18,"id":1,"name":"張三","password":"123456"}

至此ssm配置已經走通，springMvc主要是銜接視圖和控制器
