Class DataCenterAwareMarshallingStrategy

java.lang.Object

org.springframework.cloud.netflix.eureka.DataCenterAwareMarshallingStrategy

All Implemented Interfaces:

com.thoughtworks.xstream.MarshallingStrategy

public class DataCenterAwareMarshallingStrategy
extends Object
implements com.thoughtworks.xstream.MarshallingStrategy

A special purpose wrapper for an XStream TreeMarshallingStrategy that is aware of the InstanceInfo type and can create a more useful DataCenterInfo for it after unmarshalling. If the InstanceInfo has a metadataMap containing an instanceId, and the DataCenterInfo is not already an AmazonInfo, then the instanceId is used to create an identifier, but appending it to the existing one. This is useful when not running Eureka in bare EC2 VMs, so the EC2 metadata is not available for uniquely identifying the InstanceInfo (the default is to just use the hostname, but that isn't very useful when sitting behind a proxy).
