MyBatis Plus代码生成器

AutoGenerator 是 MyBatis-Plus 的代码生成器，通过 AutoGenerator 可以快速生成 Entity、Mapper、Mapper XML、Service、Controller 等各个模块的代码，极大的提升了开发效率。

在pom中添加：

启动类 MyBatisPlusGenerator：

package com.xiling;

import java.sql.SQLException;

import javax.sql.DataSource;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.baomidou.mybatisplus.enums.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.DbType;
import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;

public class MyBatisPlusGenerator {

    public static void main(String[] args) throws SQLException {

        //1. 全局配置
        GlobalConfig config = new GlobalConfig();
        config.setActiveRecord(true) // 是否支持AR模式
                .setAuthor("****") // 作者
                //.setOutputDir("D:\\workspace_mp\\mp03\\src\\main\\java") // 生成路径
                .setOutputDir("***\\src\\main\\java") // 生成路径
                .setFileOverride(true)  // 文件覆盖
                .setIdType(IdType.AUTO) // 主键策略
                .setServiceName("%sService")  // 设置生成的service接口的名字的首字母是否为I
                // IEmployeeService
                .setBaseResultMap(true)//生成基本的resultMap
                .setBaseColumnList(true);//生成基本的SQL片段

        //2. 数据源配置
        DataSourceConfig  dsConfig  = new DataSourceConfig();
        dsConfig.setDbType(DbType.MYSQL)  // 设置数据库类型
                .setDriverName("com.mysql.jdbc.Driver")
                .setUrl("jdbc:mysql://localhost:3306/**")
                .setUsername("root")
                .setPassword("");

        //3. 策略配置globalConfiguration中
        StrategyConfig stConfig = new StrategyConfig();
        stConfig.setCapitalMode(true) //全局大写命名
                .setDbColumnUnderline(true)  // 指定表名 字段名是否使用下划线
                .setNaming(NamingStrategy.underline_to_camel) // 数据库表映射到实体的命名策略
                //.setTablePrefix("tbl_")
                .entityTableFieldAnnotationEnable(true);


        ;  // 生成的表

        //4. 包名策略配置
        PackageConfig pkConfig = new PackageConfig();
        pkConfig.setParent("com.**")
                .setMapper("dao")//dao
                .setService("service")//servcie
                .setController("controller")//controller
                .setEntity("entity")
                .setXml("dao.mapper");//mapper.xml

        //5. 整合配置
        AutoGenerator  ag = new AutoGenerator();
        ag.setGlobalConfig(config)
                .setDataSource(dsConfig)
                .setStrategy(stConfig)
                .setPackageInfo(pkConfig);

        //6. 执行
        ag.execute();
    }

}

执行main方法，生成成功：
