（java）在springboot中使用mybatis-plus自动生成代码

第一步：导入坐标

  <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.5.1</version>
        </dependency>
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-generator</artifactId>
            <version>3.5.1</version>
        </dependency>
        <!--模板引擎-->
        <dependency>
            <groupId>org.apache.velocity</groupId>
            <artifactId>velocity-engine-core</artifactId>
            <version>2.3</version>
        </dependency>
        <!--swagger3-->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-boot-starter</artifactId>
            <version>3.0.0</version>
        </dependency>
        <!--freemarker模板-->
        <dependency>
            <groupId>org.freemarker</groupId>
            <artifactId>freemarker</artifactId>
        </dependency>

第二步：创建一个类：

package com.ag.generator;

import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.baomidou.mybatisplus.generator.FastAutoGenerator;
import com.baomidou.mybatisplus.generator.config.OutputFile;
import com.baomidou.mybatisplus.generator.engine.FreemarkerTemplateEngine;

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;

public class My {
    public static void main(String[] args) {
        List<String> tables = new ArrayList<>();
        tables.add("tb_activity");
        tables.add("tb_building");
        tables.add("tb_car");
        tables.add("tb_charge_detail");
        tables.add("tb_charge_item");
        tables.add("tb_community");
        tables.add("tb_complaint");
        tables.add("tb_device");
        tables.add("tb_estate_manager");
        tables.add("tb_house");
        tables.add("tb_letter");
        tables.add("tb_owner");
        tables.add("tb_parking");
        tables.add("tb_parking_use");
        tables.add("tb_pet");
        tables.add("tb_repair");
        String property = System.getProperty("user.dir");//当前的工作目录
        FastAutoGenerator.create("jdbc:mysql://localhost:3306/xiaoniu-estate?serverTimezone=GMT%2B8","root","root")
                .globalConfig(builder -> {
                    builder.author("小牛")               //作者
                            .outputDir(property+"\\src\\main\\java")    //输出路径(写到java目录)
                            .enableSwagger()           //开启swagger
                            .commentDate("yyyy-MM-dd")
                            .fileOverride();            //开启覆盖之前生成的文件

                })
                .packageConfig(builder -> {
                    builder.parent("com.ag")
//                            .moduleName("practice")
                            .entity("pojo")
                            .service("service")
                            .serviceImpl("serviceImpl")
                            .controller("controller")
                            .mapper("mapper")
                            .xml("mapper")
                            .pathInfo(Collections.singletonMap(OutputFile.mapperXml,property+"\\src\\main\\resources\\mapper"));
                })
                .strategyConfig(builder -> {
                    builder.addInclude(tables)
                            .addTablePrefix("tb_")
                            .serviceBuilder()
                            .formatServiceFileName("%sService")
                            .formatServiceImplFileName("%sServiceImpl")
                            .entityBuilder()
                            .enableLombok()
                            .logicDeleteColumnName("deleted")
                            .enableTableFieldAnnotation()
                            .controllerBuilder()
                            .formatFileName("%sController")
                            .enableRestStyle()
                            .mapperBuilder()
                            .enableBaseResultMap()  //生成通用的resultMap
                            .superClass(BaseMapper.class)
                            .formatMapperFileName("%sMapper")
                            .enableMapperAnnotation()
                            .formatXmlFileName("%sMapper")
                            .controllerBuilder().enableRestStyle();//restful开启
                })
                .templateEngine(new FreemarkerTemplateEngine()) // 使用Freemarker引擎模板，默认的是Velocity引擎模板
                .execute();
    }
}

结果：
