接口的使用
io.netty.resolver.NameResolver

使用NameResolver的程序包

程序包	说明
io.netty.resolver	Resolves an arbitrary string that represents the name of an endpoint into an address.
io.netty.resolver.dns	An alternative to Java's built-in domain name lookup mechanism that resolves a domain name asynchronously, which supports the queries of an arbitrary DNS record type as well.

io.netty.resolver中NameResolver的使用

实现NameResolver的io.netty.resolver中的类

限定符和类型	类和说明
class	CompositeNameResolver<T> A composite SimpleNameResolver that resolves a host name against a sequence of NameResolvers.
class	DefaultNameResolver A InetNameResolver that resolves using JDK's built-in domain name lookup mechanism.
class	InetNameResolver A skeletal NameResolver implementation that resolves InetAddress.
class	RoundRobinInetAddressResolver A NameResolver that resolves InetAddress and force Round Robin by choosing a single address randomly in SimpleNameResolver.resolve(String) and SimpleNameResolver.resolve(String, Promise) if multiple are returned by the NameResolver.
class	SimpleNameResolver<T> A skeletal NameResolver implementation.

参数类型为NameResolver的io.netty.resolver中的构造器

构造器和说明
CompositeNameResolver(EventExecutor executor, NameResolver<T>... resolvers)
InetSocketAddressResolver(EventExecutor executor, NameResolver<java.net.InetAddress> nameResolver)
RoundRobinInetAddressResolver(EventExecutor executor, NameResolver<java.net.InetAddress> nameResolver)

io.netty.resolver.dns中NameResolver的使用

实现NameResolver的io.netty.resolver.dns中的类

限定符和类型	类和说明
class	DnsNameResolver A DNS-based InetNameResolver.

返回NameResolver的io.netty.resolver.dns中的方法

限定符和类型	方法和说明
protected NameResolver<java.net.InetAddress>	DnsAddressResolverGroup.newNameResolver(EventLoop eventLoop, ChannelFactory<? extends DatagramChannel> channelFactory, DnsServerAddressStreamProvider nameServerProvider) Creates a new NameResolver.

参数类型为NameResolver的io.netty.resolver.dns中的方法

限定符和类型	方法和说明
protected AddressResolver<java.net.InetSocketAddress>	RoundRobinDnsAddressResolverGroup.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 resolve(java.lang.String) by InflightNameResolver created in DnsAddressResolverGroup.newResolver(EventLoop, ChannelFactory, DnsServerAddressStreamProvider).
protected AddressResolver<java.net.InetSocketAddress>	DnsAddressResolverGroup.newAddressResolver(EventLoop eventLoop, NameResolver<java.net.InetAddress> resolver) Creates a new AddressResolver.
