寫了一個spring boot項目，啓動時報錯，報錯內容如下
Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
ERROR [-,,,] 13688 --- [ 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).
看出來是一些DataSource的url有問題，所以修改了yml文件
1. 查看pom中是否有對應的依賴包
2. 修改了url
3. 修改driverClassName爲driver-class-name
改完還是報錯，後來看到啓動日誌有這樣一段話：
JSR-330 'javax.inject.Inject' annotation found and supported for autowiring
Bean 'configurationPropertiesRebinderAutoConfiguration' of type [org.springframework.cloud.autoconfigure.ConfigurationPropertiesRebinderAutoConfiguration$$EnhancerBySpringCGLIB$$419e3f38] is not eligible for getting processed by all BeanPostProcessors (for example: not eligible for auto-proxying)
說明啓動文件沒有將配置文件加載完畢，修改 所以看了看classpath文件，是source缺少了引用resource的設置
添加了resource配置就可以正產啓動了
