Processing IP addresses in WebService

In the WebService, write:

Import Javax.annotation.Resource;
Import Javax.servlet.http.HttpServletRequest;
Import Javax.xml.ws.WebServiceContext;
Import Javax.xml.ws.handler.MessageContext;

Import org.apache.cxf.transport.http.AbstractHTTPDestination;
Import org.springframework.beans.factory.annotation.Autowired;

@Resource
Private Webservicecontext context;

The container automatically injects the websericecontext into the attribute.

public void getipaddress () {

Messagecontext CTX = Context.getmessagecontext ();

HttpServletRequest request = (httpservletrequest) ctx.get (abstracthttpdestination.http_request);

String ip=request.getremoteaddr (); Get address

}

Attached: Get detailed city and county via IP:

Write this class first, this is the IP query location via an interface on the Internet

Import Java.io.BufferedReader;
Import Java.io.DataOutputStream;
Import java.io.IOException;
Import Java.io.InputStreamReader;
Import java.net.HttpURLConnection;
Import Java.net.URL;
