代码生成器之Mybatis-Plus（基础版）

1. 导入依赖

        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-generator</artifactId>
            <version>3.2.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.velocity</groupId>
            <artifactId>velocity-engine-core</artifactId>
            <version>2.3</version>
        </dependency>

2. 编写生成类

package com.example.generator;

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 Simple {
    public static void main(String[] args) {
        AutoGenerator autoGenerator = new AutoGenerator();
        GlobalConfig globalConfig = new GlobalConfig();
        globalConfig.setOutputDir("C:\\Users\\HZC\\Desktop\\layui");
        globalConfig.setAuthor("hzc");
        globalConfig.setMapperName("%sMapper");
        globalConfig.setServiceName("%sService");
        globalConfig.setServiceImplName("%sServiceImpl");
        autoGenerator.setGlobalConfig(globalConfig);

        autoGenerator.setGlobalConfig(globalConfig);


        DataSourceConfig sourceConfig = new DataSourceConfig();
        sourceConfig.setDriverName("com.mysql.cj.jdbc.Driver");
        sourceConfig.setUrl("jdbc:mysql://localhost:3306/jwsystem?serverTimezone=UTC");
        sourceConfig.setUsername("root");
        sourceConfig.setPassword("123456");
        autoGenerator.setDataSource(sourceConfig);


        PackageConfig packageConfig = new PackageConfig();
        packageConfig.setParent("com.example");
        autoGenerator.setPackageInfo(packageConfig);

        // TODO 策略配置
        StrategyConfig strategy = new StrategyConfig();
        // 数据库表映射到实体的命名策略，驼峰原则
        strategy.setNaming(NamingStrategy.underline_to_camel);
        // 字数据库表字段映射到实体的命名策略，驼峰原则
        strategy.setColumnNaming(NamingStrategy.underline_to_camel);
        // 实体是否生成 serialVersionUID
        strategy.setEntitySerialVersionUID(false);
        // 是否生成实体时，生成字段注解
        strategy.setEntityTableFieldAnnotationEnable(true);
        // 使用lombok
        strategy.setEntityLombokModel(true);
        // 设置逻辑删除键
        strategy.setLogicDeleteFieldName("del_flag");
        // 驼峰转连字符
        strategy.setControllerMappingHyphenStyle(true);
        autoGenerator.setStrategy(strategy);

        autoGenerator.execute();

    }
}
