### 环境的搭建 ###

*  创建maven项目

[创建Maven的Java Web项目][Maven_Java Web]

*  导入所需要的jar包的依赖

> 其中spring5以上，要用json，必须要3.0版本以上的

*  导入Bootstrap(前端美化框架)

> 只需要去官网下载，然后放到项目中就行

            MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
            myBatisGenerator.generate(null);
        }
