spring+spring-mvc+mybatis框架的设备管理系统

开发软件工具版本：idea 2017+jdk1.8+Tomcat8.0+maven3.9+mysql8.0
框架 spring+spring mvc+mybatis
用了过滤器、拦截器、监听器
功能实现了用户登录，设备的增删改查

项目结构如图所示，框架包用maven下载，pom文件里配置

控制层
controller
用户登录的控制器
UserController

package com.controller;

设备管理的控制器
DeviceController

package com.controller;

/**

import com.pojo.Device;
import com.pojo.User;
import com.service.DeviceService;

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.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.servlet.http.HttpServletRequest;

@Controller
@RequestMapping("/device")
public class DeviceController {
    @Autowired
    private DeviceService deviceService;


    @RequestMapping("/allDevice")
    public String list(Model model,HttpServletRequest request) {
        long status=((User)request.getSession().getAttribute("loginUser")).getUserStatus();
        List<Device> list = deviceService.queryAllDevice(status);
        model.addAttribute("list", list);
        return "allDevice";
    }

    @RequestMapping("toAddDevice")
    public String toAddPaper() {
        return "addDevice";
    }

    @RequestMapping("/addDevice")
    public String addPaper(Device device) {
        deviceService.addDevice(device);
        return "redirect:/device/allDevice";
        //return "allPaper";
    }

    @RequestMapping("/del/{paperId}")
    public String deletePaper(@PathVariable("paperId") Long id) {
        deviceService.deleteDeviceById(id);
        return "redirect:/device/allDevice";
    }

    @RequestMapping("toUpdateDevice")
    public String toUpdatePaper(Model model, Long id) {
        model.addAttribute("device", deviceService.queryById(id));
        return "updateDevice";
    }

    @RequestMapping("/updateDevice")
    public String updatePaper(Model model, Device device) {
        //System.out.println("要删除的id"+device.getPaperId());
        deviceService.updateDevice(device);
        device = deviceService.queryById(device.getDeviceId());
        model.addAttribute("device", device);
        return "redirect:/device/allDevice";
    }
}

不会前端啊，所以只是简单的实现一下功能而已，路过的大佬见谅
