java如何获得当前时间？java获取请求对象的计算机ip和网络ip的方法是什么？具体如何用自己写的相应代码调用代码如下::packagebeanimport Java . io . *；import Java . util . *；public class IP { staticpublicHashMapping；//ping后的结果集publichhashmapgtping(){//用于获取ping后的结果集，returnping}//当前线程的数量。
publicstringgetipadr(http servlet request request){ if(request . get header(xforwardedfor)null){ return request . getremote addr()；} return request . get header(xforwardedfor)；}。

只需获取ip地址，request . getremote addr()；然后存储图片的路径，你自己设置。不就是公网的路径吗？这个得不到是因为有代理、端口映射等等转发的情况。Publicstaticvoidmain(String1。获取LAN网段，可以通过自己机器的IP来确定(也可以手动获取主机ipcmipconfig/all)。2.根据IP类型，一次性遍历局域网中的IP地址JAVA类，编译后直接运行，得到局域网中的所有IP。具体怎么用自己写的对应代码调用代码如下::packagebeanimport Java . io . *；import Java . util . *；public class IP { staticpublicHashMapping；//ping后的结果集publichhashmapgtping(){//用于获取ping后的结果集，returnping}//当前线程的数量，
publistaticstringethostipaddress(){ stringostip；inetaddressnetaddressgetinetdress()；hostIpgetHostIp(net address)；returnhostIp} publistaticinetaddressgetineaddress(){ try { returninetaddress . getlocalhost()；} catch(unknownhostexception){ system . out . println(unknown host！);} returnnull} publistaticstringethostip(InetAddressnetAddress){ if(nullnet address){ return null；} stringipnetaddress . gethostaddress()；//gettheipaddressreturnip；} publicstaticStringgetH .

简单实现代码如下:获取源页面地址的js方法:varurldocument.referrerdocument . write(URL)；Jsp获取源页面地址的方法:stringurlrequest。get header(\ referer \)；system . out . println(URL)；比较两种方法:1.js是“referer”，jsp是“referer”，前者比后者多一个“r”；
inetaddressmyipaddressinetdress . get localhost()；system . out . println(my IP address)；//microsof 7a 9453/192 . 168 . 2 . 10 stringipmyipaddress . tostring()；//先改成string system . out . println(IP . substring(16))；//192.168.2.10【从第16位开始显示到结束】。
8、java如何获取当前时间,java如何获取ip地址Get当前时间publistaticvoidmain(string[]args)throwsioexception { simpledateformatnewsimpledateformat(yyyymmdd hh:mm:ss)；system . out . println(format . format(new date()))；}获取ip地址publicstaticvoidmain(string[]args)throwsioexception { inetaddressnetaddress inetaddress。get localhost()；System.out.println(ip地址:net address . gethostaddress())；System.out.println(主机名:net address . get hostname())；}其实用InetAddress.getLocalHost()获取ip是有问题的，因为有的电脑有多个网卡，所以有多个ip地址，正确的方法应该是public。
