cloud.aws.jdbc.datasource Throwing Assertion Error: Password Must Not Be Null for Spring Boot App

Question

我目前正在处理一个项目，其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，当我运行申请时，我收到以下错误：

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

我不确定为什么上面的设置看起来没问题，但它告诉我密码为空。

任何建议都会有所帮助。如果我需要提供其他任何东西，请告诉我。

谢谢。

我运行陷入同样的问题。我的配置与您的类似：

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 cloud.aws.rds.springdemo 解决了问题，因此只有

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

留了下来。在那之后，我没有收到任何断言错误，我的 spring 启动应用程序能够启动。
