改字符编码 setting->editor->File Encodeing 全部修改成UTF-8注解生效激活 setting->build…->compiler->annotation…->右侧 enable 勾上java编辑版本 setting->build…->compiler->java compliler 选1.8File Types过滤 setting->editor->File Types .hprof;.idea;.iml;.pyc;.pyo;.rbc;.yarb;~;.DS_Store;.git;.hg;.svn;CVS;pycache;_svn;vssver.scc;vssver2.scc;1.新建maven项目:demo2020 2.改pom

4.建数据库、建表
