今天在写ServerSocket的时候，遇到了socket地址的通配符地址、环回地址。

package com.thb;

import java.io.IOException;
import java.net.InetAddress;
import java.net.ServerSocket;

public class ServerSocketMain {

	public static void main(String[] args) {
		try {			
			ServerSocket server = new ServerSocket(22335);
			InetAddress local = server.getInetAddress();
			System.out.println("ServerSocket绑定的地址："+ server.getInetAddress());
			System.out.println("是否通配符地址：" + local.isAnyLocalAddress());
			System.out.println("是否环回地址：" + local.isLoopbackAddress());
			System.out.println("环回地址：" + InetAddress.getLoopbackAddress());			

		} catch (IOException e) {			
			e.printStackTrace();
		}

	}

}

执行输出：
