Mybatis-Plus自动生成代码

第一步：

导入依赖包（记得导入自己数据库的依赖包）

        <!-- mybatis-plus-->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.5.0</version>
        </dependency>
        <!-- mybatis-plus 代码生成器依赖（注意避免版本冲突，版本必须是：3.3.2）-->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-generator</artifactId>
            <version>3.3.2</version>
        </dependency>
        <!--mybatis plus 逆向工程需要模板引擎-->
        <dependency>
            <groupId>org.freemarker</groupId>
            <artifactId>freemarker</artifactId>
            <version>2.3.28</version>
        </dependency>
        <!--end-->
        <!--mysql的依赖包-->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <scope>runtime</scope>
        </dependency>

 

第二步：

写mybatis-plus代码器工具类

package com.gc.util;

import com.baomidou.mybatisplus.core.toolkit.StringPool;
import com.baomidou.mybatisplus.generator.AutoGenerator;
import com.baomidou.mybatisplus.generator.InjectionConfig;
import com.baomidou.mybatisplus.generator.config.*;
import com.baomidou.mybatisplus.generator.config.po.TableInfo;
import com.baomidou.mybatisplus.generator.config.rules.DateType;
import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;
import com.baomidou.mybatisplus.generator.engine.FreemarkerTemplateEngine;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
public class MyBatisGeneratorUtil {

    public static void main(String[] args) {

        AutoGenerator mpg = new AutoGenerator();

        GlobalConfig gc = new GlobalConfig();

        String projectPath = System.getProperty("user.dir");
        gc.setOutputDir(projectPath + "/src/main/java");
        gc.setAuthor("gaoqin");
        gc.setOpen(false);


        gc.setServiceName("%sService");

        gc.setServiceImplName("%sServiceImpl");

        gc.setMapperName("%sMapper");

        gc.setXmlName("%sMapper");

        gc.setFileOverride(true);

        gc.setActiveRecord(false);

        gc.setEnableCache(false);

        gc.setBaseResultMap(true);

        gc.setBaseColumnList(false);

        gc.setDateType(DateType.ONLY_DATE);

        gc.setActiveRecord(false);

        mpg.setGlobalConfig(gc);

        //对应自己数据库的信息
        DataSourceConfig dsc = new DataSourceConfig();
        dsc.setUrl("jdbc:mysql://127.0.0.1:3306/first?useUnicode=true&useSSL=false&characterEncoding=utf8&serverTimezone=UTC");
        dsc.setDriverName("com.mysql.jdbc.Driver");
        dsc.setUsername("root");
        dsc.setPassword("root");
        mpg.setDataSource(dsc);


        //包配置
        PackageConfig pc = new PackageConfig();
        pc.setParent("com.gc");
        pc.setEntity("bean"); //实体类
        pc.setService("service");
        pc.setServiceImpl("service.impl");
        pc.setMapper("dao");
        pc.setController("controller");
        mpg.setPackageInfo(pc);

        InjectionConfig cfg = new InjectionConfig() {
            @Override
            public void initMap() {
                // to do nothing
            }
        };

        List<FileOutConfig> focList = new ArrayList<>();
        focList.add(new FileOutConfig("/templates/mapper.xml.ftl") {
            public String outputFile(TableInfo tableInfo) {
                String projectPath = System.getProperty("user.dir");
                return projectPath + "/src/main/resources/mappers/"
                        + "/" + tableInfo.getEntityName() + "Mapper" + StringPool.DOT_XML;
            }
        });

        cfg.setFileOutConfigList(focList);
        mpg.setCfg(cfg);
        mpg.setTemplate(new TemplateConfig().setXml(null));

        StrategyConfig strategy = new StrategyConfig();

        strategy.setNaming(NamingStrategy.underline_to_camel);
        strategy.setColumnNaming(NamingStrategy.underline_to_camel);

        strategy.setLogicDeleteFieldName("deleted");
        strategy.setInclude("emp","dept");//逆向工程使用的表

        strategy.setControllerMappingHyphenStyle(true);
        mpg.setStrategy(strategy);

        mpg.setTemplateEngine(new FreemarkerTemplateEngine());
        mpg.execute();
    }

}

第三步：最后运行该类就行了
