Failed to load property source from 'file:/*****/target/classes/application.yml' (classpath:/application.yml)

　　使用springboot默認創建項目，是application.properties,改成yml格式時，需要注意以下幾點：

• 注釋中不能用中文
• yml格式，采用tree形狀，key和value中的“冒號",冒號與值之間要有空格，如 username: root
• 同一級別節點格式要對齊,下面紅包部分由於沒有對齊，運行項目時報錯

　　yml中格式錯誤，肉眼不太容易找出錯誤，推薦一個在線查看的工具：http://old.qqe2.com/jsontool/yaml.php
