Preface:

I've used the most convenient code generator, and it's really powerful!

Build code generator:

1. Add dependency:

(1) Code generator dependency

(2) Lombok depends on

Using lombok can reduce code development

 1          <dependency>
 2             <groupId>org.projectlombok</groupId>
 3             <artifactId>lombok</artifactId>
 4             <version>1.18.0</version>
 5             <scope>provided</scope>
 6         </dependency>
 7         <!-- Add code generator dependencies -->
 8         <dependency>
 9             <groupId>org.apache.velocity</groupId>
10             <artifactId>velocity-engine-core</artifactId>
11             <version>2.0</version>
12         </dependency>                

2. Write generator:

 6 import com.baomidou.mybatisplus.generator.AutoGenerator;
 7 import com.baomidou.mybatisplus.generator.config.DataSourceConfig;
 8 import com.baomidou.mybatisplus.generator.config.GlobalConfig;
 9 import com.baomidou.mybatisplus.generator.config.PackageConfig;
10 import com.baomidou.mybatisplus.generator.config.StrategyConfig;
11 import com.baomidou.mybatisplus.generator.config.rules.DbType;
12 import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;
