mybatis-plus

自动生成

使用Mybatis-plus-generator

导入依赖

       <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.4.2</version>
        </dependency>
   
   <dependency>
      <groupId>com.baomidou</groupId>
      <artifactId>mybatis-plus-generator</artifactId>
      <version>3.5.1</version>
    </dependency>

        <!--velocity模板-->
        <dependency>
            <groupId>org.apache.velocity</groupId>
            <artifactId>velocity-engine-core</artifactId>
            <version>2.3</version>
        </dependency>
        <!--freemarker模板-->
        <dependency>
            <groupId>org.freemarker</groupId>
            <artifactId>freemarker</artifactId>
        </dependency>

​ 在test包下新建CodeGenerator

package com.butu.bird.Helper;


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 CodeGenerator {
    public static void main(String[] args) {
        List<String> tables = new ArrayList<>();
        tables.add("user");//需要生成的表


        FastAutoGenerator.create("jdbc:mysql://localhost:3306/book?useUnicode=true&characterEncoding=utf-8&useSSL=false&useLegacyDatetimeCode=false&serverTimezone=Asia/Shanghai","root","root")
                .globalConfig(builder -> {
                    builder.author("BUTUbird")               //作者
                            .outputDir(System.getProperty("user.dir")+"\\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.butu")
                            .moduleName("bird")
                            .entity("entity")
                            .service("service")
                            .serviceImpl("serviceImpl")
                            .controller("controller")
                            .mapper("mapper")
                            .xml("mapper")
                            .pathInfo(Collections.singletonMap(OutputFile.mapperXml,System.getProperty("user.dir")+"\\src\\main\\resources\\mapper"));
                })
                .strategyConfig(builder -> {
                    builder.addInclude(tables)
                            //.addTablePrefix("p_") //过滤表名前缀
                            .serviceBuilder()
                            .formatServiceFileName("%sService")
                            .formatServiceImplFileName("%sServiceImpl")
                            .entityBuilder()
                            .enableLombok()
                            .logicDeleteColumnName("deleted")
                            .enableTableFieldAnnotation()
                            .controllerBuilder()
                            .formatFileName("%sController")
                            .enableRestStyle()
                            .mapperBuilder()
                            .superClass(BaseMapper.class)
                            .formatMapperFileName("%sMapper")
                            .enableMapperAnnotation()
                            .formatXmlFileName("%sMapper");
                })
                .templateEngine(new FreemarkerTemplateEngine()) // 使用Freemarker引擎模板，默认的是Velocity引擎模板
                .execute();
    }
}

创建完成之后运行main函数自动生成需要的类。
