はその後、下記の私は私の性質に配置された構成がファイルです。

spring.datasource.url = jdbc:mysql://127.0.0.1/test 
spring.datasource.username = root 
spring.datasource.password = 

spring.jpa.hibernate.ddl-auto = create-drop 

spring.datasource.testWhileIdle = true 
spring.datasource.timeBetweenEvictionRunsMillis = 60000 
spring.datasource.validationQuery = SELECT 1 

私のミスだったかもしれない何？次のエラーが表示されます。

URLを正しく設定していないようです。 MYSQLはポート3306で利用できます。しかし、あなたのURLでは、あなたはそのポートに注意しなかった。
