eclipse生成mybatis的逆向工程-mybatis代码自动生成

　　首先，工作中一直在使用命令方式的mybatis的代码自动生成，今天把自己的笔记本直接搞一个在eclipse中生成的逆向代码生成工程，方便自己在家学习使用，在搞这个工程的过程中由于自己搞了一套环境，所i出现了一些问题，最后解决了，在这里首先写出来，给自己提个醒

　　出的问题主要是在下载代码生成的jar时和逆向生成代码时出的问题

　　本博主因为自己在linux centos上搞了一套私服，打算以后一直采用这个，所以在jar时因为忘了这个事，所以jar没有下载出来，以后一定要先把私服打开，连上网，同时关闭防火墙

　　第二，就是逆向代码生成报错，可以先编译一下，在生成，如果还不行就去认真检查generatorConfig.xml是否有配错的地方。

接着我们上代码

我们创建mybatis-generator的springboot工程，这里面可以删除逆向工程不需要的运行主程序和测试主程序以及测试资源包等结构i，然后就是配置了
