Class SystemPropertyCredentialsResolver

java.lang.Object

com.northconcepts.datapipeline.security.SystemPropertyCredentialsResolver

All Implemented Interfaces:

CredentialsResolver

public class SystemPropertyCredentialsResolver
extends Object
implements CredentialsResolver

A CredentialsResolver that reads credential values from JVM system properties at each resolve.

Map logical credential keys to system property names:

 new SystemPropertyCredentialsResolver()
         .map(Credentials.ACCESS_KEY, "s3.accessKey")
         .map(Credentials.SECRET_KEY, "s3.secretKey");
 

Unset properties are omitted from the returned Credentials. Since system properties can change at runtime, this resolver reports isRotating() as true.
