新手日志：mac系统跑springboot的jar报错：To display the conditions report re-run your application with 'debug'...

• 运行jar时报错：

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
2021-08-06 13:59:03.887 ERROR 25750 --- [           main] o.s.b.d.LoggingFailureAnalysisReporter   :

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

Description:

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be 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).

• 分析重点：

o.s.b.d.LoggingFailureAnalysisReporter   

• 原因：logger方面出的问题，检查自己的logger在properties中配置的路径为/home/xxx/。由于在mac目录中没有/home/目录，虽然打包成功了，但是运行时会出错，并且在centos中即使有/home/目录也无法运行。
  解决办法：修改mac中logger配置的目录为/opt/xxx （centos中也有opt目录），再给mac中的/opt/xxx目录赋予读写权限: sudo chmod +x 777 /opt/xxx

• 最后：报错To display the conditions report re-run your application with 'debug' enabled.的原因有多种，具体要看其后面一行去找错误的具体原因。
