Failed to configure ‘url‘ attribute is not specified and no embedded datasource could be configured.

遇到一个奇怪问题：

新拉的项目启动报错：

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).

 尝试了很多方法都不行。

发现问题====>问题汇总：没有读取到yml配置文件

1.pom文件没有指定

指定resources目录：

<resource>
   <directory>src/main/resources</directory>
</resource>

 

2.原因是idea没有指定resource目录，启动项目时导致没读取到配置文件就报上面错误

look--------->resources颜色都不对

解决办法：

右键resources文件夹 -> MarkDirectory as ->Sources Root 如图：

look--------->resources有颜色了，哈哈哈哈哈

 

从新run项目，跑起来了，完美解决。

记得+关注呀！！！
