關於獲取本機IP地址的幾種方法

我本機的IP地址是：

使用代碼獲取：

%@ page import="java.net.InetAddress" %>
<%@ page import="java.net.UnknownHostException" %>
<%@ page import="java.net.InetAddress" %>
<%@ page import="java.io.PrintWriter" %>

<%
    /*設置編碼*/
    request.setCharacterEncoding("UTF-8");
    response.setContentType("text/html;charset=UTF-8");
    final PrintWriter writer = response.getWriter();


    writer.println("獲得客戶端IP地址：" + request.getLocalAddr() + "<br/>");
    writer.println("獲取本機的IP地址：" + request.getRemoteAddr() + "<br/>");

    InetAddress address = null;
    try {
        address = InetAddress.getLocalHost();
        //獲取計算機名稱和ip地址
        writer.println("獲取計算機名稱和ip地址:" + address + "<br/>");
        String hostAddress = address.getHostAddress();
        //獲取ip地址
        writer.println("獲取本機的IPV4地址:" + hostAddress + "<br/>");
        String hostName = address.getHostName();
        //獲取計算機名稱
        writer.println("獲取計算機名稱:" + hostName + "<br/>");
    } catch (UnknownHostException e) {
        e.printStackTrace();
    }
%>

打印的結果是：
