org.apache.dubbo.metadata

接口 ServiceNameMapping

所有超级接口:

org.apache.dubbo.rpc.service.Destroyable

所有已知实现类:

AbstractServiceNameMapping

@SPI(value="metadata",
     scope=APPLICATION)
public interface ServiceNameMapping
extends org.apache.dubbo.rpc.service.Destroyable

This will interact with remote metadata center to find the interface-app mapping and will cache the data locally. Call variants of getCachedMapping() methods whenever need to use the mapping data.
