maven+springboot项目clone到本地后
1.根据idea提示recrate为maven项目(右侧maven选项卡可以看到是否为maven项目)。
2.idea连接远程数据库（右侧datebase选项卡）。
3.运行报错：重启idea以激活数据库的配置文件
Consider the following:
If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).
另附：idea的汉化
