1、配置项目启动类
package com.echo.blog;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* @className AppRun
* @author Echo
* @description 启动类配置
* @updateTime 2021/12/11 21:59
* @version 1.0
*/
@SpringBootApplication
public class AppRun {
public static void main(String[] args) {
SpringApplication.run(AppRun.class,args);
}
}
2、配置Mybatis-plus逆向生成类所需要的数据库配置
dataSource.url=jdbc:mysql://localhost:3306/blog?useUnicode=true&characterEncoding=utf-8&serverTimezone=Asia/Shanghai&useSSL=false
dataSource.driverName=com.mysql.cj.jdbc.Driver
dataSource.username=root
dataSource.password=admin
package.base=com.echo.blog.modules
3、配置Mybatis-plus逆向生成类
package com.echo.blog.init.generator;
import cn.hutool.core.util.StrUtil;
import cn.hutool.setting.dialect.Props;
import com.baomidou.mybatisplus.core.exceptions.MybatisPlusException;
import com.baomidou.mybatisplus.core.toolkit.StringPool;

import com.baomidou.mybatisplus.generator.engine.VelocityTemplateEngine;
import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;
