• mybatis-plus 代码自动生成


    先创建一个springboot项目

    目录结构

     pom.xml

    添加依赖

    kuang

    package com;
    
    import com.baomidou.mybatisplus.annotation.DbType;
    import com.baomidou.mybatisplus.annotation.IdType;
    import com.baomidou.mybatisplus.generator.config.DataSourceConfig;
    import com.baomidou.mybatisplus.generator.config.GlobalConfig;
    import com.baomidou.mybatisplus.generator.AutoGenerator;
    import com.baomidou.mybatisplus.generator.config.PackageConfig;

    import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;
    import com.baomidou.mybatisplus.generator.engine.FreemarkerTemplateEngine;
    
    public class kuang {
        public  static void main(String[] args){
    //        需要构建一个 代码生成器 对象
            AutoGenerator mpg = new AutoGenerator();
            //配置策略
            //1、全局配置
            GlobalConfig gc = new GlobalConfig();
            String projectPath=System.getProperty("user.dir");
            gc.setOutputDir(projectPath + "/src/main/java");
            gc.setAuthor("凯宾斯基");//输入作者
            gc.setOpen(false); //是否打开文件夹
            gc.setFileOverride(false); //是否覆盖
            gc.setServiceName("%Service"); //去掉Server的I前缀
            gc.setIdType(IdType.ID_WORKER); //id正常算法
            gc.setDateType(DateType.ONLY_DATE); //时间格式
    //        gc.setSwagger2(true);//配置swagger文档
            mpg.setGlobalConfig(gc);
    
            //2、设置数据源配置
            DataSourceConfig dsc=new DataSourceConfig();
            dsc.setUrl("jdbc:mysql://localhost:3306/datademo?serverTimezone=UTC");
            dsc.setDriverName("com.mysql.cj.jdbc.Driver");
            dsc.setUsername("root");
            dsc.setPassword("669988");
            dsc.setDbType(DbType.MYSQL);
            mpg.setDataSource(dsc);
    
    
            //3、包的配置
            PackageConfig pc =new PackageConfig();
            pc.setParent("com.kuang");  //父母亲
            pc.setModuleName("bolg");  // 模块名称
            pc.setEntity("entity");  //实体
            pc.setMapper("mapper"); //制图员
            pc.setService("service"); //服务
            pc.setController("controller"); //控制
            mpg.setPackageInfo(pc);
    
            // 策略配置
            StrategyConfig strategy = new StrategyConfig();
            strategy.setInclude("user2","user"); //设置要映射的表名
            strategy.setNaming(NamingStrategy.underline_to_camel);
            strategy.setColumnNaming(NamingStrategy.underline_to_camel);
            strategy.setEntityLombokModel(true); //自动lombok
            strategy.setLogicDeleteFieldName("deleted");
            mpg.setStrategy(strategy);
    
            mpg.execute();//执行
        }
    }

    包配置生成的目录如下

    可以在策略配置那里放多个表 生成对应的实体类
