代码自动生成
作者：互联网
最近开发几个查询接口,从代码来看，基本的格式都是一样的。就想着写一个代码生成工具。直接生成代码。省时省力。经过测试，生成的代码完全可用，节省了至少80%的时间。这里做一个记录。以后有类似的情况就可以拿来改一改就可以用了。
package com.insigma.business.uploadreport.zCode;
import cn.hutool.core.util.StrUtil;
import java.io.*;
import java.net.URISyntaxException;
import java.util.*;
/**
* 自动生成代码
* 查询接口代码自动生成工具：只需定义好要生成的接口 功能名称，注释信息，列表接口和详情接口的入参出参。
* 就可以生成controller，service，mapper的相应方法。
* 注意：生成的provider中对应的查询方法是留空的。需要自己完善。
