软件工程开学测试新闻发布Mis系统

一、对于本次测试的感想

  1. 由于上学期和假期里的学习，对于javaweb系统也是比较了解了，所以对于这次测试还是有把握的。
  2. 经过了上个学期的几次测试，我也得出了一些得分的外门邪道，其中最主要的原则就是要快，所以我把我掌握的最方便快捷知识都拿出来使用了。
  3. 当然快只是针对考试而言，在平时学习的时候也要系统全面的学习。

二、部分代码

基于springboot+vue实现,只是使用了vue的指令，未实现前后端分离

domain实体类曾以News为例使用lombok实现

package com.example.domain;
 
import lombok.Data;
 
import java.util.Date;
 
@Data
public class News {
    int id;
    String title;
    String name;
    String content;
    Date time;
    String lanmu;
    String sug;
    String pinglun;
    String fabu;
}

dao层采用mybatis-plus实现

package com.example.dao;
 
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.example.domain.User;
import org.apache.ibatis.annotations.Mapper;
 
@Mapper
public interface UserDao extends BaseMapper<User> {
}

service层省略，未写

controller层以NewsController为例

package com.example.controller;
 
import com.baomidou.mybatisplus.core.conditions.Wrapper;
import com.baomidou.mybatisplus.core.conditions.query.LambdaQueryWrapper;
import com.example.dao.NewsDao;
import com.example.dao.OffdocDao;
import com.example.domain.News;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
 
import java.net.Inet4Address;
import java.util.Date;
import java.util.List;
 
@RestController
@RequestMapping("/news")
public class NewsController {
    @Autowired
    private NewsDao newsDao;
 
    @PostMapping("/create")
    public boolean craete(@RequestBody News news){
        news.setTime(new Date());
        news.setFabu("待发");
        newsDao.insert(news);
        return true;
    }
    @GetMapping("/getAll")
    public List<News> getAll(){
        return newsDao.selectList(null);
    }
    @PostMapping("/upd")
    public boolean upd(@RequestBody News news){
        newsDao.updateById(news);
        return true;
    }
    @PostMapping("/chaxun1")
    public  List<News> chaxun1(@RequestBody News news){
        System.out.println("条件为---------------" + news.getTitle());
        LambdaQueryWrapper<News> qw = new LambdaQueryWrapper<>();
        qw.eq(News::getTitle, news.getTitle());
        List<News> list = newsDao.selectList(qw);
        return list;
    }
    @PostMapping("/chaxun2")
    public  List<News> chaxun2(@RequestBody News news){
        LambdaQueryWrapper<News> qw = new LambdaQueryWrapper<>();
        qw.eq(News::getName, news.getName());
        List<News> list = newsDao.selectList(qw);
        return list;
    }
    @PostMapping("/chaxun3")
    public  List<News> chaxun3(@RequestBody News news){
        System.out.println("条件为---------------" + news.getTitle());
        LambdaQueryWrapper<News> qw = new LambdaQueryWrapper<>();
        qw.eq(News::getContent, news.getContent());
        List<News> list = newsDao.selectList(qw);
        return list;
    }
    @PostMapping("/chaxun4")
    public  List<News> chaxun4(@RequestBody News news){
        System.out.println("条件为---------------" + news.getTitle());
        LambdaQueryWrapper<News> qw = new LambdaQueryWrapper<>();
        qw.eq(News::getLanmu, news.getLanmu());
        List<News> list = newsDao.selectList(qw);
        return list;
    }
    @DeleteMapping("/del/{id}")
    public boolean del(@PathVariable Integer id){
        newsDao.deleteById(id);
        return true;
    }
 
}
