無法連接到MySQL在AWS

當我運行在AWS EC2實例的jar我的春天啓動的應用程序拋出錯誤。當我在本地系統中運行時，它工作正常。無法連接到MySQL在AWS

我application.properties文件

spring.datasource.driver-class-name=com.mysql.jdbc.Driver 
spring.datasource.url=jdbc:mysql://localhost:3306/gbi? useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=fa lse&serverTimezone=UTC&autoReconnect=true&failOverReadOnly=false&maxReconne cts=10 
spring.jpa.database-platform =org.hibernate.dialect.MySQLDialect 
spring.datasource.username=****** 
spring.datasource.password=******@ 
spring.datasource.pool.size=20 
spring.jpa.hibernate.ddl-auto=update 
server.port=8090

當我運行在AWS服務器的罐子，我收到以下錯誤

得EC2和點擊安全組，然後在底部添加一個新的安全組類型MYSQL /極光protocal TCP和選擇的端口號，然後在源選擇您的計算機的IP地址。你應該能夠解決您的問題。

你是什麼意思「我的電腦的ip」？我應該把電腦的IP從我部署jar的地方？ –

我認爲這是在您的本地應用程序，所以我說把你的本地計算機的IP地址。如果不是，則創建一個安全組並將其添加到入站規則中 –
