Spring+CXF配置HTTP代理訪問Internet

一個典型的CXF Webservice項目部署到正式環境後，服務器不能訪問外網，只能通過代理訪問外網，找了很多資料，剛開始想法是不用Spring的配置文件，直接用java編程訪問webservice。在java的Http請求中使用代理的方法如下：

String authentication="username:password";//用戶+”:”+密碼
        String encodedLogin= new BASE64Encoder().encode(authentication.getBytes());
        Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("IP", PORT));

        HttpsURLConnection conn = (HttpsURLConnection) console.openConnection(proxy );
        conn.setRequestProperty("Proxy-Authorization", " Basic " + encodedLogin);

使用JaxWsProxyFactoryBean創建client

System.setProperty("http.proxySet", "true");
        System.setProperty("http.proxyHost", "IP");
        System.setProperty("http.proxyPort", "PORT");

        JaxWsProxyFactoryBean f = new JaxWsProxyFactoryBean();
        f.setAddress("THE URL OF WEBSERVICE");
        f.setServiceClass(IService.class);
        IService client = (IService) f.create();

可以使用代理，但是用戶名密碼是不能像第一種方法中那樣設置到HttpConnection裏面去的。

又在網上找了很多資料，終於找到了一個配置的方法。

        <http-conf:conduit name="*.http-conduit"> 
            <http-conf:proxyAuthorization>

                    <!-- 用戶名 -->
                    <sec:UserName>***</sec:UserName>
                    <!-- 密碼 -->
                    <sec:Password>***</sec:Password>

             </http-conf:proxyAuthorization>
            <!--
                ProxyServer IP                ProxyServerPort PORT
                ProxyServerType: HTTP or SOCKS
             -->
            <http-conf:client
                    ProxyServer="192.168.1.4" 
                    ProxyServerPort="808"
                    ProxyServerType="HTTP"
                    Connection="Keep-Alive" 
                    AllowChunking="false"
                    ConnectionTimeout="50000" 
                    ReceiveTimeout="120000"
                    /> 
    </http-conf:conduit> 

    <!-- Client   -->
    </beans>

<http-conf:conduit name="*.http-conduit"> 這裏的name爲”*.http-conduit”時，將會對所有的client類啓用這個代理，如果要配置某個client類使用代理，可以這麼寫

<http-conf:conduit name="{http://widgets/widgetvendor.net}widgetSOAPPort.http-conduit>
    ...
  </http-conf:conduit>

{}裏面的內容是webservice的wsdl的<wsdl:definitions name="serviceName" targetNamespace="http://hafeyang.blogjava.net"的targetNamespace屬性

{}之後.之前的內容是

…

<wsdl:port name="BasicHttpBinding_IService" binding="i0:BasicHttpBinding_IService">

<soap:address location="the address" />

</wsdl:port>

…

的name屬性。

上述wsdl對應的配置是

<http-conf:conduit name="{http://hafeyang.blogjava.net}BasicHttpBinding_IService.http-conduit> ... </http-conf:conduit>
