mybatis plus automatically generates pojo entity classes

1. Import coordinate dependency

        <!--mybatis-plus依赖-->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.3.2</version>
        </dependency>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.17</version>
        </dependency>
        
        <!--代码生成器模板引擎-->
        <dependency>
            <groupId>org.apache.velocity</groupId>
            <artifactId>velocity-engine-core</artifactId>
            <version>2.2</version>
        </dependency>
        <!--代码生成器-->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-generator</artifactId>
            <version>3.3.2</version>
        </dependency>

Two, write automatic generation tool class'

package com.tclp.util;


import com.baomidou.mybatisplus.generator.AutoGenerator;
import com.baomidou.mybatisplus.generator.config.*;
import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;

public class MybatisPlusUtil {
    public static void main(String[] args) {

        String userDir = System.getProperty("user.dir");
        System.out.println("userDir=" + userDir);

        // 代码生成器
        AutoGenerator mpg = new AutoGenerator();

        // 全局配置
        GlobalConfig gc = new GlobalConfig();
        //获取当前的项目的路径
        String projectPath = System.getProperty("user.dir");
        System.out.println(projectPath);
        //配置生成路径
        gc.setOutputDir(projectPath + "/src/main/java");
        // 作者名称
        gc.setAuthor("rock");
        gc.setBaseResultMap(true);
        gc.setBaseColumnList(true);
        mpg.setGlobalConfig(gc);


        // 数据源配置
        DataSourceConfig dsc = new DataSourceConfig();
        dsc.setUrl("jdbc:mysql://localhost:3306/java220401?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull");
        dsc.setDriverName("com.mysql.jdbc.Driver");
        dsc.setUsername("root");
        dsc.setPassword("1234");
        mpg.setDataSource(dsc);

        // 包配置
        PackageConfig pc = new PackageConfig();
        pc.setParent("com.hqyj");
        pc.setController("controller");
        pc.setEntity("pojo");
        pc.setMapper("dao");

        mpg.setPackageInfo(pc);

        // 配置模板
        TemplateConfig templateConfig = new TemplateConfig();
        //templateConfig.setXml(null);
        templateConfig.setXml("/templates/mapper.xml");
        mpg.setTemplate(templateConfig);

        // 策略配置
        StrategyConfig strategy = new StrategyConfig();
        strategy.setNaming(NamingStrategy.underline_to_camel);
        strategy.setColumnNaming(NamingStrategy.underline_to_camel);
        strategy.setEntityLombokModel(true);
        strategy.setRestControllerStyle(true);
        strategy.setInclude("power");//表名
        strategy.setControllerMappingHyphenStyle(true);
        strategy.setTablePrefix(pc.getModuleName() + "_");
        mpg.setStrategy(strategy);
        //mpg.setTemplateEngine(new FreemarkerTemplateEngine());
        mpg.execute();
    }

}
