所有已实现的接口:

java.io.Closeable, java.lang.AutoCloseable

public class RoundRobinDnsAddressResolverGroup
extends DnsAddressResolverGroup

A AddressResolverGroup of DnsNameResolvers that supports random selection of destination addresses if multiple are provided by the nameserver. This is ideal for use in applications that use a pool of connections, for which connecting to a single resolved address would be inefficient.

protected AddressResolver<java.net.InetSocketAddress>

newAddressResolver(EventLoop eventLoop, NameResolver<java.net.InetAddress> resolver) We need to override this method, not DnsAddressResolverGroup.newNameResolver(EventLoop, ChannelFactory, DnsServerAddressStreamProvider), because we need to eliminate possible caching of NameResolver.resolve(java.lang.String) by InflightNameResolver created in DnsAddressResolverGroup.newResolver(EventLoop, ChannelFactory, DnsServerAddressStreamProvider).

We need to override this method, not DnsAddressResolverGroup.newNameResolver(EventLoop, ChannelFactory, DnsServerAddressStreamProvider), because we need to eliminate possible caching of NameResolver.resolve(java.lang.String) by InflightNameResolver created in DnsAddressResolverGroup.newResolver(EventLoop, ChannelFactory, DnsServerAddressStreamProvider).

覆盖:

newAddressResolver 在类中 DnsAddressResolverGroup

抛出:

java.lang.Exception
