技術標籤：專案實戰IDEA常見問題

如題，完整報錯如下：

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).

由報錯資訊可以看出問題是沒有配置資料來源，而明顯我的配置檔案裡是有配置DataSource的，找了很久才發現問題，就是打包的時候沒有把配置檔案載入進去。
所以應該在pom檔案中加入resources標籤中程式碼即可
