// 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

}

return ipAddress;

方法调用：
(当接口 /test 被调用，request就能自动获取出来，然后调用工具类方法进行解析获取了。)
@RequestMapping(value = "/test", method = RequestMethod.GET)
public String test(HttpServletRequest request){
//获取IP地址
String ipAddress =IpUtil.getIpAddr(request);
return ipAddress;
}
