### set log levels ###
#log4j.rootLogger = debug , stdout , D , E

10 . 编写jsp和controller代码

WEB-INF/jsp/index.jsp






Insert title here
ssm搭建完成！！！

WEB-INF/jsp/allusers.jsp








Insert title here
ssm搭建完成！！！
    id-------------用户昵称
    

    ${user.id }-------------${user.nickname }

cn.SpringDemo.controller/UserComtroller.java

package cn.SpringDemo.controller;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import cn.SpringDemo.model.User;
import cn.SpringDemo.model.result.ResultDO;
import cn.SpringDemo.service.UserService;

/**
 * 用户Controller
 * @author yezi
 *
 */
@Controller
@RequestMapping("/")
public class UserController {

    @Autowired
    private UserService userService;

    /**
     * 测试
     * @return
     */
    @RequestMapping("index")
    public String index(){
        return "index";
    }

    @RequestMapping("showAllUsers")
    public String showAllUsers(Model model) {
        ResultDO> resultDO = userService.getAllUsers();
        model.addAttribute("users", resultDO.getResult());
        return "allUsers";
    }
}

11.发布运行

将项目部署到tomcat8.5.16中

访问路径localhost:8080/SpringDemo/index.do

访问路径localhost:8080/SpringDemo/showAllUsers.do
