cloud.aws.jdbc.datasource 抛出断言错误：Spring Boot 应用程序的密码不能为空

Question

我目前正在开展一个项目，我们的应用程序需要在该项目中连接到 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，我应该将 application.properties 文件设置为：

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：

我不知道为什么当上面的设置看起来不错时，它告诉我密码为空。

任何的意见都将会有帮助。如果我需要提供其他任何东西，请告诉我。

谢谢。

我遇到了同样的问题。我的配置与您的配置类似：

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

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

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

留下了。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。
