简单CXF方式的webService客户端调用范例

简单CXF方式的webService客户端调用范例

文章分类:Java编程

    一般webServices发布后需要测试一下,是否可行通，在此我把自己所测试的 调用 webService 的简单范例贴出来供新手参考。如有不足，请多指教。

 

1：需要借助的包： wss4j-1.5.4.jar    cxf-bundle-2.1.3.jar

2：

 

package con.transnal.ucenter.client;

import java.lang.reflect.Proxy;
import java.util.HashMap;
import java.util.Map;

//import net.sxinfo.ucenter.services.UCenterService;
//此处就为你发布的 webService的 源代码，此处我把它打成 jar 包了.
//一般在开发中,你可以建一个webService Clietn 来引用 webService的wsdl

import org.apache.cxf.binding.soap.saaj.SAAJOutInterceptor;
import org.apache.cxf.configuration.jsse.TLSClientParameters;
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.ws.security.wss4j.WSS4JOutInterceptor;
import org.apache.ws.security.WSConstants;
import org.apache.ws.security.handler.WSHandlerConstants;
import org.junit.Test;

/**

public class UCenterServiceClientTest {

    @Test
    public void testCreateUser() throws Exception {
        UCenterService ucenterService = getUCenterService();
        String result = ucenterService.createUser("renweigang", "123456789",  "[e-mail]");
        System.out.println(result);
    }

    private UCenterService getUCenterService() {
        return getNotSSLUCenterService();
    }

    private UCenterService getNotSSLUCenterService()
    {
        JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
        factory.setServiceClass(UCenterService.class);
//此处的地址为对方发布的 webService的地址。
        factory.setAddress("http://uc./ucenter/ucenter/services/UCenterService");
        System.setProperty("org.apache.cxf.bus.factory", "org.apache.cxf.bus.CXFBusFactory");
        UCenterService ucenterService = (UCenterService) factory.create();
        ClientProxy proxy = (ClientProxy) Proxy.getInvocationHandler(ucenterService);
        Client client = proxy.getClient();
        // ③添加流模型和DOM模型转换的Handler

        //client.getOutInterceptors().add(new SAAJOutInterceptor());

        Map<String,Object> properties = new HashMap<String,Object>();
        // ④-1动作
        properties.put(WSHandlerConstants.ACTION, WSHandlerConstants.USERNAME_TOKEN + " " + WSHandlerConstants.TIMESTAMP);
        // PW_TEXT 明文 ,PW_DIGEST 摘要
        // PasswordDigest是通过非保密渠道发送用户名和口令的最佳方法。即使使用XML加密对<wsse:Password>元素进行加密，PasswordText依然可以使用

        properties.put(WSHandlerConstants.USER, "services-test");// ④-3指定用户
        properties.put(WSHandlerConstants.PASSWORD_TYPE, WSConstants.PW_TEXT);
        properties.put(WSHandlerConstants.PW_CALLBACK_CLASS, UtPasswordHandler.class.getName());
        WSS4JOutInterceptor wss4j = new WSS4JOutInterceptor(properties);
        client.getOutInterceptors().add(wss4j);


        return ucenterService;
    }
}

public class UtPasswordHandler implements CallbackHandler {
    // ①客户端用户模拟数据库

    private static final Map<String,String> pwMockDB = new HashMap<String,String>();

              //一般真正开发中,对方的webService指定用户，此处的 services-//test 为用户名，test 为密码。
    static{
    pwMockDB.put("services-test", "test");
    }

    public void handle(Callback[] callbacks) {

    WSPasswordCallback callback = (WSPasswordCallback) callbacks[0];

    String id = callback.getIdentifer();
    // ②获取用户对应的密码
    callback.setPassword(pwMockDB.get(id));
