springboot 获取访问接口的请求的IP地址的实现

工具类：

import javax.servlet.http.httpservletrequest;
import java.net.inetaddress;
import java.net.unknownhostexception;

public class iputil {
    public static string getipaddr(httpservletrequest request) {
        string ipaddress = null;
        try {
            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(","));
                }
            }
        } catch (exception e) {
            ipaddress="";
        }
        // ipaddress = this.getrequest().getremoteaddr();
 
        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;
}
