SpringBoot整合mybatis-generator-maven-plugin的方法

前言:

SpringBoot版本 : 2.2.6

mybatis-generator-maven-plugin版本: 1.4.0

plugin 使用 mysql版本: 5.1.47

本次主要记录日和使用该插件自动生成pojo mapper xml文件(单表)

1 创建SpringBoot工程

这里不做具体记录,创建工程往常教程很多,

下面贴出重要文件和注意事项

1.1 pom.xml

1.2 application.yml

server:
 port: 8080
spring:
 datasource:
  driver-class-name: com.mysql.jdbc.Driver
  url: jdbc:mysql://localhost:3306/generaltor?useUnicode=true&characterEncoding=utf-8&serverTimezone=GMT
  username: root
  password: lk0313
  druid:
   db-type: com.alibaba.druid.pool.DruidDataSource
#  下面不配置就是采用默认配置
#  filters: stat
#  maxActive: 20
#  initialSize: 1
#  maxWait: 60000
#  minIdle: 1
#  timeBetweenEvictionRunsMillis: 60000
#  minEvictableIdleTimeMillis: 300000
#  validationQuery: select 'x'
#  testWhileIdle: true
#  testOnBorrow: false
#  testOnReturn: false
#  poolPreparedStatements: true
#  maxOpenPreparedStatements: 20
mybatis:
# 该配置项配置了MyBatis配置文件保存路径
 mapper-locations: classpath*:show/makey/dao

CREATE DATAbase `generaltor` ;



DROP TABLE IF EXISTS `student`;

CREATE TABLE `student` (
 `id` int(32) NOT NULL AUTO_INCREMENT,
 `name` varchar(15) DEFAULT NULL,
 `sex` varchar(2) DEFAULT NULL,
 `phone` int(15) DEFAULT NULL,
 PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;



insert into `student`(`id`,`name`,`sex`,`phone`) values (1,'lk','男',12345578);

;
;
;
;

3 运行

如果使用IDEA 我们只需要找到右边侧栏中的maven(没有记得调出了)

找到plugins–>mybatis-generaltor–>mybatis-generaltor:generaltor 之后双击即可,此时刷新一下项目就自动生成我们想要的,mapper和xml以及pojo

4 测试

创建穿点controller和service 来完成一次测试,

package show.mrkay.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.Mapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.servlet.support.JstlUtils;
import show.mrkay.dao.StudentMapper;
import show.mrkay.pojo.Student;
import show.mrkay.service.UserService;

import java.util.List;


@RestController
@RequestMapping("/user")
public class UserController {
  @Autowired
  private UserService userService;
  @GetMapping("/alllist")
  public List selectAll(){
    return userService.selectAll();
  }
}

package show.mrkay.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import show.mrkay.dao.StudentMapper;
import show.mrkay.pojo.Student;

import java.util.List;


@Service
public class UserService {
  @Autowired
  private StudentMapper studentMapper;
  public List selectAll(){
    List students = studentMapper.selectAll();
    return students;
  }
}

package show.mrkay;

import org.mybatis.spring.annotation.MapperScan;
import org.mybatis.spring.annotation.MapperScans;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@MapperScan("show.mrkay.dao")
public class GeneratorApplication {
  public static void main(String[] args) {
    SpringApplication.run(GeneratorApplication.class, args);
  }
}

注意:

启动器类中需要加入@MapperScan(“mapper接口所在包”)注解,这样我们就不需要手动创建实现类了,mybatis会自动帮我们创建

启动之后:

地址栏输入 localhost:8080/user/alllist

得到查询结果:

[{"id":1,"name":"lk","sex":"男","phone":12345578}]
