用代码生成器生成mybaitsPlus的代码

一. pom.xml

代码语言：javascript复制

<?xml version="1.0" encoding="UTF-8"?>

        </dependency>
    </dependencies>


</project>

二.在java/src下新建类

代码语言：javascript复制

import com.baomidou.mybatisplus.annotation.IdType;
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.DateType;
import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;

public class GeneratorClass {
   
    public static void main(String[] args) {
   
        // 代码生成器
        AutoGenerator mpg = new AutoGenerator();
        //全局配置策略
        GlobalConfig gc = new GlobalConfig();
        String path = System.getProperty("user.dir");//动态获取当前项目的路径
        System.out.println(path);
        gc.setFileOverride(false);// 是否覆盖同名文件，默认是false
        gc.setActiveRecord(true);// 不需要ActiveRecord特性的请改为false
        gc.setEnableCache(false);// XML 二级缓存
        gc.setBaseResultMap(true);// XML ResultMap
        gc.setBaseColumnList(false);// XML columList
        gc.setOutputDir(path);
        gc.setIdType(IdType.AUTO);//设置主键策略
        gc.setDateType(DateType.ONLY_DATE);//生成java.util.Date类型


        //数据源配置
        DataSourceConfig dsc = new DataSourceConfig();
        dsc.setUrl("jdbc:mysql://localhost:3306/ego?useUnicode=true&useSSL=false&characterEncoding=utf8");
        // dsc.setSchemaName("public");
        dsc.setDriverName("com.mysql.jdbc.Driver");
        dsc.setUsername("root");
        dsc.setPassword("admin");

        // 包配置
        PackageConfig pc = new PackageConfig();
        pc.setParent("com.ego")
                .setMapper("mapper")
                .setService("service")
                .setController("controller")
                .setEntity("pojo")
                .setXml("mapperxml");
        //策略配置
        StrategyConfig stConfig = new StrategyConfig();
        stConfig.setCapitalMode(true) //全局大写命名
                .setNaming(NamingStrategy.underline_to_camel) // 数据库表映射到实体的命名策略
                .setTablePrefix("tb_")
                .setEntityLombokModel(true)//使用lombok
                .setInclude("tb_content","manager","tb_content_category","tb_item","tb_item_cat","tb_item_desc","tb_item_param","tb_item_param_item","tb_order","tb_order_item","tb_order_shipping","tb_user"); // 生成的表，多个表继续传递即可，String类型的可变参数

        //将策略配置对象集成到代码生成器中
        mpg.setGlobalConfig(gc);
        mpg.setDataSource(dsc);
        mpg.setPackageInfo(pc);
        mpg.setStrategy(stConfig);
        //执行生成
        mpg.execute();
    }
}

三.运行类,完成!

java xml src
