java程序如何绑定服务器IP？

你把这个方法写进你的程序,程序开始后先获取IP,然后判断IP是否和你的一致,如果不一致直接return即可.

/**

* 获取外网IP

* @param request

* @return

*/

public static String getIpAddr(HttpServletRequest request) {

String ipAddress = null

// ipAddress = this.getRequest().getRemoteAddr()

ipAddress = request.getHeader("x-forwarded-for")

if (ipAddress == null || ipAddress.length() == 0

|| "unknown".equalsIgnoreCase(ipAddress)) {

ipAddress = request.getHeader("Proxy-Client-IP")

}

if (ipAddress == null || ipAddress.length() == 0

|| "unknown".equalsIgnoreCase(ipAddress)) {

ipAddress = request.getHeader("WL-Proxy-Client-IP")

}

if (ipAddress == null || ipAddress.length() == 0

|| "unknown".equalsIgnoreCase(ipAddress)) {

ipAddress = request.getRemoteAddr()

if (ipAddress.equals("127.0.0.1")) {

// 根据网卡取本机配置的IP

InetAddress inet = null

try {

inet = InetAddress.getLocalHost()

} catch (UnknownHostException e) {

e.printStackTrace()

}

ipAddress = inet.getHostAddress()

}

}

// 对于通过多个代理的情况，第一个IP为客户端真实IP,多个IP按照','分割

if (ipAddress != null &&ipAddress.length() >15) { // "***.***.***.***".length()

// = 15

if (ipAddress.indexOf(",") >0) {

ipAddress = ipAddress.substring(0, ipAddress.indexOf(","))

}

}

return ipAddress

}

首先IP为一个字符串,例如：

class test{

static void Split(string ip,out string str1)

{

int i=ip.length

while(i>0)

{

char ch=ip[i-1]

if(ch==':')

break

i--

}

str1=ip.Substring(0,i)

}

static void Main()

{

string str1

Split("192.168.0.255:8080",out str1)

Console.WriteLine("{0}",str1)

}

}

str1中保存的就是你的ip,192.168.0.255
