cxf设置代理访问webservice接口

时间：2022-01-04 16:16:26

　　由于业务上的需要，需要访问第三方提供的webservice接口，但由于公司做了对外访问的限制，不设置代理是不能外网的，如果使用http设置代理访问外网还是比较容易的，但使用cxf有点不知道从哪里入手。网上也有一些零散的信息，现在我整理一下提供参考。

1、JaxWsProxyFactoryBean设置代理

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设置代理

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为调用webService的wsdl地址

        Client client = dcf.createClient("http://xxx.xxxx.xxx.xxx:8080/webservice?wsdl");

        //namespace是命名空间，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());
　　　　}
　　}

}
