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
- 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。
- 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。
- 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;
}
}
