Springboot项目本地运行无问题而打成jar包出现问题Failed to auto-configure a DataSource

如题，完整报错如下：

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
2021-01-26 02:08:50.556 ERROR 4152 --- [           main] o.s.b.d.LoggingFailureAnalysisReporter   : 

***************************
APPLICATION FAILED TO START
***************************

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).

由报错信息可以看出问题是没有配置数据源，而明显我的配置文件里是有配置DataSource的，找了很久才发现问题，就是打包的时候没有把配置文件加载进去。
所以应该在pom文件中加入resources标签中代码即可

<build>
