WebService（JAX-WS、XFire、Axis三种）获取客户端ip
JAX-WS、XFire、Axis三种webservice的获取客户端IP的简单实现过程：
1，基于JDK6 jax-ws开发的webservice获取客户端IP地址，Endpoint.publish() 轻量级HTTP服务发布，在web容器tomcat下发布；
2，基于XFire开发的webservice获取客户端IP地址；
3，基于Axis开发的webservice获取客户端IP地址；
一、基于JDK6 jax-ws开发的webservice获取客户端IP地址
1，如果以Endpoint.publish()的方式发布：
服务端接口实现类代码（获取的是调用webservice的服务器的IP）：
package com.micmiu.jaxws.demo.impl;import .InetSocketAddress;import javax.annotation.Resource;import javax.jws.WebMethod;import javax.jws.WebParam;import javax.jws.WebService;import javax.xml.ws.WebServiceContext;import javax.xml.ws.handler.MessageContext;import com.micmiu.jaxws.demo.HelloService;import .httpserver.HttpExchange;import com.sun.xml.internal.ws.developer.JAXWSProperties;@WebService()public class HelloServiceImpl implements HelloService {@Resourceprivate WebServiceContext wsContext;@WebMethodpublic String sayHello(@WebParam(name = "userName") String userName) {getClientInfo();return "";}private void getClientInfo() {try {MessageContext mc = wsContext.getMessageContext();HttpExchange exchange = (HttpExchange) mc.get(JAXWSProperties.HTTP_EXCHANGE);InetSocketAddress isa = exchange.getRemoteAddress();System.out.println("InetSocketAddress : " + isa);System.out.println("Hostname : "+ isa.getAddress().getHostAddress() + " address: "+ isa.getAddress().getHostName());} catch (Exception e) {e.printStackTrace();}}}
客户端调用后，服务端运行日志：
InetSocketAddress : /192.20.100.210:52462Hostname : 192.20.100.210 address: ADMINIS-3HJ200
2，如果以web容器的方式发布（jetty 或 tomcat为例）：
服务端接口实现代码：
package com.micmiu.jaxws.demo2.impl;import javax.annotation.Resource;import javax.jws.WebService;import javax.servlet.http.HttpServletRequest;import javax.xml.ws.WebServiceContext;import javax.xml.ws.handler.MessageContext;import com.micmiu.jaxws.demo2.HelloService;@WebService(endpointInterface = "com.micmiu.jaxws.demo2.HelloService")public class HelloServiceImpl implements HelloService {@Resourceprivate WebServiceContext wsContext;public String sayHello(String userName) {String clientIP = getClientInfo();return "JAX-WS with IP: " + clientIP;}private String getClientInfo() {String clientIP = null;try {MessageContext mc = wsContext.getMessageContext();HttpServletRequest request = (HttpServletRequest) (mc.get(MessageContext.SERVLET_REQUEST));clientIP = request.getRemoteAddr();System.out.println("client IP : " + clientIP);} catch (Exception e) {e.printStackTrace();}return clientIP;}}
客户端调用后，服务端运行日志：
client IP : 192.20.100.210
二、基于XFire开发的webservice获取客户端IP地址
服务端接口实现类代码：
package com.micmiu.xfire.demo.base;import javax.servlet.http.HttpServletRequest;import org.codehaus.xfire.transport.http.XFireServletController;public class HelloWorldServiceImpl implements HelloWorldService{public String sayHello(String username){String clientIP = getClientInfo();return "";}public String getClientInfo() {String clientIP = null;try{HttpServletRequest request = XFireServletController.getRequest();System.out.println("Addr:"+request.getRemoteAddr()+" host:"+request.getRemoteHost());clientIP = request.getRemoteAddr();}catch(Exceptione){e.printStackTrace();}return clientIP;}}
客户端调用后，服务端的日志信息如下：
Addr : 192.20.100.210 host: 192.20.100.210客户端IP ：192.20.100.210
三、Axis开发的webservice获取客户端IP地址
服务端代码：
import javax.servlet.http.HttpServletRequest;import org.apache.axis.MessageContext;import org.apache.axis.transport.http.HTTPConstants;public class HelloWorld{public String sayHello(String username){String clientIP = getClientInfo();return clientIP ;}private String getClientInfo() {MessageContext mc = null;HttpServletRequest request = null;String clientIP = null;try { mc = MessageContext.getCurrentContext();request = (HttpServletRequest) mc.getProperty(HTTPConstants.MC_HTTP_SERVLETREQUEST);clientIP = request.getRemoteAddr();
System.out.println("Axis IP >>:"+clientIP);}catch (Exception e){e.printStackTrace();}return clientIP;}}
客户端调用后，服务端的日志信息如下：
Axis IP >>:192.20.100.210
注意：
在public class AuthFr extends HttpServlet(){}这种类中是获取不到客户端Ip，MessageContext.getCurrentContext()值为空；--待解决
当然，如果只是获取真实的客户端IP可以采用request.getRemoteAddr();
这里要获取的是A（真实客户端）通过访问B（服务器B）发布的网站再访问C（服务器C）的网站；这里服务器C上要获取服务器B的IP；
换句话理解就是只能通过服务器B才能访问到服务器C，其他IP都需要过滤；
这种情况，利用上诉方式在普通类中可以实现获取服务器B的IP，但是在public class AuthFr extends HttpServlet(){}这种类中确实null；
