2翁狐、在測試類中添加一個類用來生成代碼

package com.littlenorth;

import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.annotation.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.DateType;
import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;

// 代碼自動生成器
public class CodeProduct {
    public static void main(String[] args) {
        // 需要構(gòu)建一個 代碼自動生成器 對象
        AutoGenerator mpg = new AutoGenerator();

        // 配置策略
        // 1凌蔬、全局配置
        GlobalConfig gc = new GlobalConfig();
        //代碼生成的路徑
        String projectPath = System.getProperty("user.dir");
        gc.setOutputDir(projectPath+"/src/main/java");
        //作者
        gc.setAuthor("love you");
        gc.setOpen(false);
        // 是否覆蓋
        gc.setFileOverride(false);
        // 去Service的I前綴
        gc.setServiceName("%sService");

        //ID生成策略
        gc.setIdType(IdType.ID_WORKER);
        //時間生成策略
        gc.setDateType(DateType.ONLY_DATE);
        //開啟Swagger2
        gc.setSwagger2(true);
        mpg.setGlobalConfig(gc);


        //2、設(shè)置數(shù)據(jù)源
        DataSourceConfig dsc = new DataSourceConfig();
        dsc.setUrl("jdbc:mysql://localhost:3306/mybatis?useSSL=false&useUnicode=true&characterEncoding=utf-8&serverTimezone=GMT%2B8");
        dsc.setDriverName("com.mysql.cj.jdbc.Driver");
        dsc.setUsername("root");
        dsc.setPassword("123456");
        //數(shù)據(jù)庫類型
        dsc.setDbType(DbType.MYSQL);
        //設(shè)置數(shù)據(jù)源
        mpg.setDataSource(dsc);

        //3窃躲、包的配置
        PackageConfig pc = new PackageConfig();
        pc.setParent("com.littlenorth");
        pc.setEntity("entity");
        pc.setMapper("mapper");
        pc.setService("service");
        pc.setController("controller");
        mpg.setPackageInfo(pc);

        //4钦睡、策略配置
        StrategyConfig strategy = new StrategyConfig();
        // 設(shè)置要映射的表名
        strategy.setInclude("blog","student","teacher","user");
        strategy.setNaming(NamingStrategy.underline_to_camel);
        strategy.setColumnNaming(NamingStrategy.underline_to_camel);
        // 自動lombok躁倒；
        strategy.setEntityLombokModel(true);
        strategy.setRestControllerStyle(true);
        strategy.setControllerMappingHyphenStyle(true);
        mpg.setStrategy(strategy);
        //執(zhí)行
        mpg.execute();
    }
