在开发中我们经常需要获取用户IP地址,通过地址来实现一些功能,下面这篇文章主要给大家介绍了关于Java获取登录用户的IP地址的相关资料,文中通过实例代码介绍的非常详细,需要的朋友可以参考下
示例代码如下
package com.audaque.util;
import java.net.InetAddress;
import java.net.UnknownHostException;
import javax.servlet.http.HttpServletRequest;
public class GetIp {
public String getIpAddr(HttpServletRequest request){
String 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") || ipAddress.equals("0:0:0:0:0:0:0:1")){
//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;
}
}
请求地址：
1
2
3
4
5
6
7
8
public class HttpContextUtil {
private HttpContextUtil(){
}
//获取HttpServletRequest请求
public static HttpServletRequest getHttpServletRequest() {
return ((ServletRequestAttributes) Objects.requireNonNull(RequestContextHolder.getRequestAttributes())).getRequest();
}
}
调用
1

6
sysLog.setOperationTime(LocalDateTimeUtil.getCurrentDatetime());
//获取用户名
sysLog.setUsername(UserUtil.get("username", String.class));
//获取用户ip地址
HttpServletRequest request = HttpContextUtil.getHttpServletRequest();
sysLog.setIp(IPUtil.getIpAddr(request));
总结
到此这篇关于Java获取登录用户的IP地址的文章就介绍到这了
