Question

已经讨论过这个问题的几个主题，我已经尝试过实施中讨论的建议 Elastic Beanstalk -> RDS connection error using Grails

我还打开了端口，接受来自“All”的连接，用于我的EC2实例中的ICMP，TCP和UDP。
我确保我的RDS和EC2实例位于同一区域（东区）
我还在RDS默认安全组中添加了“elasticbeanstalk-default”安全组
我已在RDS CIDR设置中添加了本地计算机的IP地址，并且我可以通过SQLYog从我的计算机连接到RDS。

但是当我尝试从Elastic Beanstalk连接我的RDS实例时，我收到以下异常

我的DataSource.groovy参数如下。

production {
    dataSource {
        pooled = true
        dbCreate = "update" // one of 'create', 'create-drop','update'
        url = "jdbc:mysql://[MyEndPoint]:3306/*****"
        username = "*****"
        password = "*****"
        dialect = org.hibernate.dialect.MySQL5InnoDBDialect
        properties {
            validationQuery = "SELECT 1"
            testOnBorrow = true
            testOnReturn = true

    }

我解决了它，但是非常愚蠢的回答。

我总是觉得（想到）在NetBeans中为Grails项目构建一个新的WAR文件时，它是在“生产”环境中创建的，但事实并非如此。我必须转到项目属性并将“活动grails环境”设置更改为“生产”并修复它。

简而言之，Amazon Web Services Elastic Beanstalk正在尝试连接到我的开发环境数据库“localhost”。
