类 MigrationRuleListener

java.lang.Object

org.apache.dubbo.registry.client.migration.MigrationRuleListener

所有已实现的接口:

EventListener, ConfigurationListener, RegistryProtocolListener

@Activate
public class MigrationRuleListener
extends Object
implements RegistryProtocolListener, ConfigurationListener

Listens to from Config Center.

- Migration rule is of consumer application scope. - Listener is shared among all invokers (interfaces), it keeps the relation between interface and handler.

There are two execution points: - Refer, invoker behaviour is determined with default rule. - Rule change, invoker behaviour is changed according to the newly received rule.
