代码生成器

创建生成类Generate.java

package com.bai.config;

import com.baomidou.mybatisplus.annotation.DbType;

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.NamingStrategy;

public class Generate {

    public static void main(String[] args) {

        //创建generator对象

        AutoGenerator autoGenerator = new AutoGenerator();

        //数据源

        DataSourceConfig dataSourceConfig = new DataSourceConfig();

        dataSourceConfig.setDbType(DbType.数据库类型);

        dataSourceConfig.setDriverName("com.mysql.cj.jdbc.Driver");

        dataSourceConfig.setUsername("数据库账号");

        dataSourceConfig.setPassword("数据库密码");

        dataSourceConfig.setUrl("jdbc:mysql://localhost:3306/表名?useSSL=false&serverTimezone=UTC&characterEncoding=UTF-8");

        autoGenerator.setDataSource(dataSourceConfig);

        //全局配置

        GlobalConfig globalConfig = new GlobalConfig();

        globalConfig.setOutputDir(System.getProperty("user.dir")+"/src/main/java");

        globalConfig.setAuthor("作者");

        globalConfig.setOpen(false);

        globalConfig.setServiceName("%sService");

        autoGenerator.setGlobalConfig(globalConfig);

        //包信息

        PackageConfig packageConfig = new PackageConfig();

        packageConfig.setParent("包名");

        packageConfig.setEntity("entity");

        packageConfig.setMapper("mapper");

        packageConfig.setService("service");

        packageConfig.setServiceImpl("service.impl");

        packageConfig.setController("controller");

        autoGenerator.setPackageInfo(packageConfig);

        //策略配置

        StrategyConfig strategyConfig = new StrategyConfig();

        strategyConfig.setInclude("要生成的表名");

        strategyConfig.setNaming(NamingStrategy.underline_to_camel);

        strategyConfig.setColumnNaming(NamingStrategy.underline_to_camel);

        strategyConfig.setEntityLombokModel(true);

        autoGenerator.setStrategy(strategyConfig);

        //运行

        autoGenerator.execute();

    }

}

配置application.yml

spring:

  datasource:

    url: jdbc:mysql://localhost:3306/表名?useSSL=false&serverTimezone=UTC&characterEncoding=UTF-8

    username: 数据库账号

    password: 数据库密码
