1分钟左右完成一个Bean管理的后端部分

基于Springboot MybatisPlus Maven框架

在安全性低、功能简单的小型项目上使用非常快

package com.humor.courseselection.controller;

import com.humor.courseselection.bean.Teacher;
import com.humor.courseselection.service.ITeacherService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.bind.annotation.RequestMapping;

import java.util.List;

@RestController
@RequestMapping("/courseselection/teacher")
public class TeacherController {
    @Autowired
    private ITeacherService iTeacherService;
    @RequestMapping("/add")
    public String  add(Teacher teacher)
    {
        try {
            if (teacher.getId()==null)
            {
                if (iTeacherService.insert(teacher))
                    return "添加成功";
            }
            else
            {
                if (iTeacherService.updateById(teacher))
                    return "修改成功";
            }
        }catch (Exception e)
        {
            e.printStackTrace();
        }
        return "数据有误，提交失败";
    }
    @RequestMapping("/del")
    public String del(int id)
    {
        try {
            if (iTeacherService.deleteById(id))
                return "删除成功";
        }catch (Exception e)
        {
            e.printStackTrace();
        }
        return "删除失败,刷新后重试";
    }
    @RequestMapping("/getById")
    public Teacher getById(int id )
    {
        return iTeacherService.selectById(id);
    }
    @RequestMapping("/getAll")
    public List<Teacher> getAll()
    {
        return iTeacherService.selectList(null);
    }
}

只需要拿着复制进去，对

iTeacherService

iTeacherService

Teacher

teacher

等几个关键字符串进行替换成新的就行，即可在1分钟左右完成一个Bean管理的后端部分
