java.lang.Object

com.netflix.client.SimpleVipAddressResolver

All Implemented Interfaces:

VipAddressResolver

public class SimpleVipAddressResolver
extends java.lang.Object
implements VipAddressResolver

A "VipAddress" in Ribbon terminology is a logical name used for a target server farm. This class helps interpret and resolve a "macro" and obtain a finalized vipAddress.

Ribbon supports a comma separated set of logcial addresses for a Ribbon Client. Typical/default implementation uses the list of servers obtained from the first of the comma separated list and progresses down the list only when the priorr vipAddress contains no servers.

This class assumes that the vip address string may contain marcos in the format of ${foo}, where foo is a property in Archaius configuration, and tries to replace these macros with actual values.

e.g. vipAddress settings ${foo}.bar:${port},${foobar}:80,localhost:8080 The above list will be resolved by this class as apple.bar:80,limebar:80,localhost:8080 provided that the Configuration library resolves the property foo=apple,port=80 and foobar=limebar
