1.5 基于MyBatis数据库逆向生成工具,并创建serverice和controller控制层

news2024/11/25 6:55:55

步骤1：在mybatis-generator中添加要生成的数据库表名
在genratorConfig.xml内容:

<!-- 数据库表 -->
<table tableName="stu"></table>

步骤2：StuMapper.xml和StuMapper拷贝到对应的mapper模块下
在这里插入图片描述

步骤3：pojo对应Stu.java 拷贝到pojo模块下
在这里插入图片描述

步骤4：创建service接口和对应的实现类
StuService接口：

package com.one.service;
import com.one.pojo.Stu;
public interface StuService {
    public Stu getStuInfo(int id);
}

StuServiceImpl实现类：

package com.one.service.impl;
import com.one.mapper.StuMapper;
import com.one.pojo.Stu;
import com.one.service.StuService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;
@Service
public class StuServiceImpl implements StuService {
    @Autowired
    public StuMapper stuMapper;
    @Transactional(propagation = Propagation.SUPPORTS)
    @Override
    public Stu getStuInfo(int id) {
        return stuMapper.selectByPrimaryKey(id);
    }
}

步骤5：创建controll控制层

package com.one.controller;
import com.one.service.StuService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class StuFooController {
    @Autowired
    private StuService stuService;
    @GetMapping("/getStu")
    public Object getStu(int id) {
        return stuService.getStuInfo(id);
    }
}

步骤6：启动类上添加,扫描mybatis通用 mapper所在的包

package com.one;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import tk.mybatis.spring.annotation.MapperScan;
/**
 * 启动类
 * @date: 2023年06月17日 15:39
 */
@SpringBootApplication
@MapperScan(basePackages="com.one.mapper")
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}
