有任何适用于micronaut应用程序的AWS处理程序吗？

Question

我正在尝试将应用程序部署到AWS Elastic Beanstalk并陷入数据库连接问题。

我已经创建了DB Instance，DB Cluster，并且已经像这样设置了Environment's variable。

这是我的application.yml

datasources:
    default:
        url: ${JDBC_URL:`jdbc:mysql://localhost:3306/test_authentication?autoReconnect=true&useUnicode=true&characterEncoding=UTF-8&useSSL=false`}
        username: ${JDBC_USER:root}
        password: ${JDBC_PASSWORD:root}
        driverClassName: ${JDBC_DRIVER:com.mysql.jdbc.Driver}

我确定我的数据库存在。

这是我最新的日志。
