SpringBoot Mybatis plus reverse generation Entity Controller Mapper Service (idea)

1. Create a springboot project

The following figure can be skipped directly, and then directly write pom.xml

2. Edit pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

</project>

 

3. Create application.yml under the resource folder (the original application.properties can be deleted)

The content is as follows

spring:
  datasource:
    url: jdbc:mysql://127.0.0.1:3306/p?serverTimezone=CTT&useUnicode=true&characterEncoding=UTF-8
    driver-class-name: com.mysql.jdbc.Driver
    username: root
    password: "111000"

mybatis-plus:
  global-config:
    #主键类型  0:"数据库ID自增", 1:"用户输入ID",2:"全局唯一ID (数字类型唯一ID)", 3:"全局唯一ID UUID";
    id-type: 0

4. Write the MpGenerator class

The content of MpGenerator.java is as follows

package com.yn.springbootmybatis.db;

import com.baomidou.mybatisplus.generator.AutoGenerator;
import com.baomidou.mybatisplus.generator.config.DataSourceConfig;
import com.baomidou.mybatisplus.generator.config.GlobalConfig;
import com.baomidou.mybatisplus.generator.config.PackageConfig;
import com.baomidou.mybatisplus.generator.config.StrategyConfig;
import com.baomidou.mybatisplus.generator.config.rules.DbType;
import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;

/**
 * @author chen
 * @date 2018/7/20 10:33
 */
public class MpGenerator {

    private static String url = "jdbc:mysql://localhost:3306/p?serverTimezone=CTT";
    private static String user = "root";
    private static String password = "111000";
    private static String dirverName = "com.mysql.jdbc.Driver";
    private static String author = "吴亦凡";
    private static String outputDir = "src\\main\\java\\com\\wuyifan\\springbootmybatis";
    private static String packageName = "domain";//生成的东西放在这个包里

    public static void main(String[] args) {
        GlobalConfig config = new GlobalConfig();
        String dbUrl = url;
        DataSourceConfig dataSourceConfig = new DataSourceConfig();
        dataSourceConfig.setDbType(DbType.MYSQL)
                .setUrl(dbUrl)
                .setUsername(user)
                .setPassword(password)
                .setDriverName(dirverName);
        StrategyConfig strategyConfig = new StrategyConfig();
        strategyConfig
                .setCapitalMode(true)
                .setEntityLombokModel(false)
                .setDbColumnUnderline(true)
                .setNaming(NamingStrategy.underline_to_camel);
        config.setActiveRecord(false)
                .setEnableCache(false)
                .setAuthor(author)
                .setOutputDir(outputDir)
                .setFileOverride(true)
                .setServiceName("%sService");
        new AutoGenerator().setGlobalConfig(config)
                .setDataSource(dataSourceConfig)
                .setStrategy(strategyConfig)
                .setPackageInfo(
                        new PackageConfig()
                                .setParent(packageName)
                                .setController("controller")
                                .setEntity("entity")
                ).execute();
    }
}

5. Execution results

Remember, the @Controller annotation in the controller class zh generated by the template is changed to @RestController
