启动项目的时候报错：
Description:
Failed to auto-configure a DataSource: 'spring.datasource.url' is not specified and no embedded datasource could be auto-configured.
Reason: Failed to determine a suitable driver class
Action:
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).
查看target目录下的包，发现class目录下没有将resources的conf/properties打包进去，连接数据库的时候找不到对应配置。自然抛出spring.datasource.url未找到的错误。
暂未找到为什么无法打包进去的原因。在pom文件增加一段配置解决此问题
