我目前正在处理一个项目，在该项目中我们的应用程序需要连接到 Amazon RDS 实例。到目前为止，我一直在使用以下文档进行设置： https ://cloud.spring.io/spring-cloud-aws/spring-cloud-aws.html#_sdk_credentials_configuration 。

根据文档，第 7.3 节，我应该这样设置我的 application.properties 文件：

cloud.aws.credentials.accessKey=XXXXXXXXXXXXXXX
cloud.aws.credentials.secretKey=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
cloud.aws.credentials.instanceProfile=true

cloud.aws.region.static=us-east-2

cloud.aws.rds.instanceNameTest
cloud.aws.rds.instanceNameTest.password=chownTestPW
cloud.aws.rds.instanceNameTest.username=dataTest1
cloud.aws.rds.instanceNameTest.databaseName=testDB

但是，当我运行应用程序时，我收到以下错误：

Caused by: java.lang.IllegalArgumentException: Password must not be null

我不确定为什么当上面的设置看起来很好时它告诉我密码为空。

任何的意见都将会有帮助。让我知道我是否需要提供其他任何东西。

谢谢。

我遇到了同样的问题。我的配置与您的配置相似：

cloud.aws.rds.springdemo
cloud.aws.rds.springdemo.databaseName=springdemo
cloud.aws.rds.springdemo.username=springdemo
cloud.aws.rds.springdemo.password=Everyday123

我通过删除属性解决了这个问题cloud.aws.rds.springdemo，所以只有

cloud.aws.rds.springdemo.databaseName=springdemo
cloud.aws.rds.springdemo.username=springdemo
cloud.aws.rds.springdemo.password=Everyday123

留下了。之后，我没有收到任何断言错误，并且我的 Spring Boot 应用程序能够启动。
