IllegalArgumentException Being Thrown When Password Is Not Null

[brobusf21]

Hello,

I am experiencing an issue in which an IllegalArgumentException is being thrown because my RDS instance's password must not be null. However, I have confirmed by checking my AWS console that the password is not null and I'm unsure why this error is getting thrown; therefore, it's either a bug or it's something I am doing wrong. My application.properties file looks like the following:

cloud.aws.credentials.accessKey=XXXXXXXXXXXXXXXX
cloud.aws.credentials.secretKey=XXXXXXXXYYYYYYYYZZZZZZZ
cloud.aws.credentials.instanceProfile=true

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

cloud.aws.rds.testInstance
cloud.aws.rds.testInstance.password=Testing123

I commented out the last three lines given that they were not making a difference.

Any thoughts or pointers would be very helpful.

Thanks.

I have the same issue.

application.properties
cloud.aws.region.static=us-east-1
cloud.aws.rds.test
cloud.aws.rds.test.databaseName=test
cloud.aws.rds.test.password=P@ssword
cloud.aws.rds.test.readReplicaSupport=true

pom.xml

org.springframework.cloud
spring-cloud-aws-jdbc

I noticed that AmazonRdsDataSourceFactoryBean is the responsible for creating the DataSource based on the above configuration.

The only way to set the password seems to be via its constructor which seems not to be called. Instead, the createInstance method is called which ends up not setting the password field (just reads from it). Moreover, password doesn't have a setter.

Additionally, the class AmazonRdsReadReplicaAwareDataSourceFactoryBean extends from AmazonRdsDataSourceFactoryBean, and having configured readReplicaSupport=true, one will suppose that the createInstance of this class would be called instead, but that isn't the case.

@aemruli Any thoughts? Is this a bug or is it missing configuration? How can I fix it?

Thanks in advance!

I got the same error and solved by removing the below entry.

Does the stack overflow answer resolve this issue?

Hello, yes the issue is solved but the official documentation hasn’t been changed which can and was misleading. Thanks for reaching out.
