cxf設定代理訪問webservice介面

　　由於業務上的需要，需要訪問第三方提供的webservice介面，但由於公司做了對外訪問的限制，不設定代理是不能外網的，如果使用http設定代理訪問外網還是比較容易的，但使用cxf有點不知道從哪裡入手。網上也有一些零散的資訊，現在我整理一下提供參考。

1、JaxWsProxyFactoryBean設定代理

import org.apache.cxf.configuration.security.ProxyAuthorizationPolicy;
import org.apache.cxf.endpoint.Client;
import org.apache.cxf.frontend.ClientProxy;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
import org.apache.cxf.transport.http.HTTPConduit;
import org.apache.cxf.transports.http.configuration.HTTPClientPolicy;

public class TeacherService {
    
    public String getStudents(StudentCard card){
        JaxWsProxyFactoryBean factoryBean = new JaxWsProxyFactoryBean();  
        factoryBean.setServiceClass(TeacherWebService.class);  
        factoryBean.setAddress("http://xxx.xxx.xxx.xxx/webservice?wsdl");  
        TeacherWebService tService = (TeacherWebService )factoryBean.create();  
            
    　　 Client client = ClientProxy.getClient(tService);
        HTTPConduit http = (HTTPConduit) client.getConduit();
        HTTPClientPolicy hcp = new HTTPClientPolicy();
        hcp.setProxyServer(proxyHost);
        hcp.setProxyServerPort(proxyport);
        http.setClient(hcp);

        ProxyAuthorizationPolicy proxyAuthorization = new ProxyAuthorizationPolicy();
        proxyAuthorization.setUserName(proxyUsername);
        proxyAuthorization.setPassword(proxyPassword);
        http.setProxyAuthorization(proxyAuthorization);
        
        String res = tService.getStudents(card);
        
        return res;
    }
}

2、使用JaxWsDynamicClientFactory設定代理

import java.net.Authenticator;
import java.net.PasswordAuthentication;
import javax.xml.namespace.QName;
import org.apache.cxf.endpoint.Client;
import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;
import com.thoughtworks.xstream.XStream;

public class TeacherService {
    
    public String getStudents(StudentCard card)throws Exception{
 　　　　 System.setProperty("http.proxyHost","http.proxy.host");
        System.setProperty("http.proxyPort", "http.proxy.port");
        Authenticator.setDefault(new MyAuthenticator("username", "password")));
        
        JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();  
        
         //url為呼叫webService的wsdl地址  
        Client client = dcf.createClient("http://xxx.xxxx.xxx.xxx:8080/webservice?wsdl");  
        //namespace是名稱空間，methodName是方法名 
        QName name=new QName("http://www.xxxx.com","getStudents");  
 　　　　XStream xstream = new XStream(new XppDriver(new XmlFriendlyNameCoder("_-", "_")));
        Object[] objects = client.invoke(name,xstream.toXML(card)); 
        
        String res = "";
        if(objects != null && objects.length != 0){
            res = objects[0].toString();
        }
        
        return res;
　　}

　　static class MyAuthenticator extends Authenticator {
　　　　private String username, password;

　　　　public MyAuthenticator(String username, String password) {
　　　　　　this.username = username;
　　　　　　this.password = password;
　　　　}

　　　　protected PasswordAuthentication getPasswordAuthentication() {
　　　　　　return new PasswordAuthentication(username, password.toCharArray());
　　　　}
　　}

}
