WebService（JAX-WS、XFire、Axis三种）获取客户端ip

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 java.net.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 com.sun.net.httpserver.HttpExchange;
import com.sun.xml.internal.ws.developer.JAXWSProperties;

@WebService()
public class HelloServiceImpl implements HelloService {

    @Resource
    private WebServiceContext wsContext;

    @WebMethod
    public 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 : /192.20.100.210:52462
Hostname : 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 {

    @Resource
    private 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；
