CXF 入门：HelloWorld接口发布
CXF 入门: 远程接口调用
下面具体的webservice实现类直接用的是上面的，这里不再说明
CXF拦截器使用,创建一个使用SOAPHeader的安全验证
xml格式：
<soap:Header>
<auth:authentication xmlns:auth="http://gd.chinamobile.com//authentication">
<auth:systemID>1</auth:systemID>
<auth:userID>test</auth:userID>
<auth:password>test</auth:password>
</auth:authentication>
</soap:Header>
一，首先在服务端创建一个拦截器(被调用端)，需要继承org.apache.cxf.phase.AbstractPhaseInterceptor
代码如下：
import java.util.List;
import javax.xml.soap.SOAPException;
import org.apache.cxf.binding.soap.SoapHeader;
import org.apache.cxf.binding.soap.SoapMessage;
import org.apache.cxf.headers.Header;
import org.apache.cxf.helpers.XMLUtils;
import org.apache.cxf.interceptor.Fault;
import org.apache.cxf.phase.AbstractPhaseInterceptor;
import org.apache.cxf.phase.Phase;
import org.apache.log4j.Logger;
import org.w3c.dom.Element;
import org.w3c.dom.NodeList;
public class AuthIntercetpr extends AbstractPhaseInterceptor<SoapMessage> {
private static final Logger logger = Logger.getLogger(AuthIntercetpr.class);
public static final String xml_namespaceUR_att = "http://gd.chinamobile.com//authentication";
public static final String xml_header_el = "soap:Header";
public static final String xml_authentication_el = "auth:authentication";
public static final String xml_systemID_el = "auth:systemID";
public static final String xml_userID_el = "auth:userID";
public static final String xml_password_el = "auth:password";
public AuthIntercetpr() {
// 指定该拦截器在哪个阶段被激发
super(Phase.PRE_INVOKE);
}
// 处理消息
public void handleMessage(SoapMessage message) {
logger.info("==================SoapMessage =" + message);
// 获取SOAP消息的全部头
List<Header> headers = message.getHeaders();
if (null == headers || headers.size() < 1) {
throw new Fault(new SOAPException("SOAP消息头格式不对哦！"));
}
for (Header header : headers) {
SoapHeader soapHeader = (SoapHeader) header;
// 取出SOAP的Header元素
Element element = (Element) soapHeader.getObject();
logger.info("ELEMENT =" + element.toString());
XMLUtils.printDOM(element);
NodeList userIdNodes = element
.getElementsByTagName(xml_userID_el);
NodeList pwdNodes = element
.getElementsByTagName(xml_password_el);
NodeList systemIdNodes = element
.getElementsByTagName(xml_systemID_el);
logger.info("############ 打印帐号信息 ##############");
logger.info(userIdNodes.item(0) + "="
+ userIdNodes.item(0).getTextContent());
logger.info(systemIdNodes.item(0) + "="
+ systemIdNodes.item(0).getTextContent());
logger.info(pwdNodes.item(0) + "="
+ pwdNodes.item(0).getTextContent());
logger.info("############————————##############");
if (null != userIdNodes
&& userIdNodes.item(0).getTextContent().equels("test") ) {
if (null != pwdNodes
&& pwdNodes.item(0).getTextContent().equals("test")) {
logger.info("$$$$$$$$ 认证成功");
} else {//认证失败则抛出异常，停止继续操作
SOAPException soapExc = new SOAPException("阁下可能不是合法用户！");
throw new Fault(soapExc);
}
} else {//认证失败则抛出异常，停止继续操作
SOAPException soapExc = new SOAPException("阁下可能不是合法用户！");
throw new Fault(soapExc);
}
}
}
}
二，修改cxf-beans.xml
<!--id:随意配，implementor：指定接口具体实现类，address:随意配，访问时会用到,下面会做说明-->
<!--拦截器-->
<bean id="authIntercetpr" class="unitTest.AuthIntercetpr"></bean>
<jaxws:endpoint id="HelloWorldService" implementor="com.ws.HelloWorldServiceImpl"
address="/IHelloService">
<!-- 在此配置调用当前ws所触发的拦截器-->
<jaxws:inInterceptors><ref bean="authIntercetpr" /></bean>
<!--或者直接在这里写<bean class="unitTest.AuthIntercetpr"></bean>-->
</jaxws:inInterceptors>
</jaxws:endpoint>
到此服务端工作完毕！！！
下面是客户端（调用端）
三，这边同样创建一个拦截器，实现org.apache.cxf.binding.soap.interceptor.AbstractSoapInterceptor
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.List;
import javax.xml.namespace.QName;
import org.apache.cxf.binding.soap.SoapHeader;
import org.apache.cxf.binding.soap.SoapMessage;
import org.apache.cxf.binding.soap.interceptor.AbstractSoapInterceptor;
import org.apache.cxf.headers.Header;
import org.apache.cxf.helpers.DOMUtils;
import org.apache.cxf.helpers.XMLUtils;
import org.apache.cxf.interceptor.Fault;
import org.apache.cxf.phase.Phase;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
public class AddSoapHeader extends AbstractSoapInterceptor {
public static final String xml_namespaceUR_att = "http://gd.chinamobile.com//authentication";
public static final String xml_header_el = "soap:Header";
public static final String xml_authentication_el = "auth:authentication";
public static final String xml_systemID_el = "auth:systemID";
public static final String xml_userID_el = "auth:userID";
public static final String xml_password_el = "auth:password";
public AddSoapHeader() {
// 指定该拦截器在哪个阶段被激发
super(Phase.WRITE);
}
public void handleMessage(SoapMessage message) throws Fault {
SimpleDateFormat sd = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date date = new Date();
String time = sd.format(date);
String userId = "test";
String sysId = "1";
String password = "test";
QName qname = new QName("RequestSOAPHeader");//这个值暂时不清楚具体做什么用，可以随便写
Document doc = (Document) DOMUtils.createDocument();
Element root = doc.createElement(xml_header_el);
Element eSysId = doc.createElement(xml_systemID_el);
eSysId.setTextContent(sysId);
Element eUserId = doc.createElement(xml_userID_el);
eUserId.setTextContent(userId);
Element ePwd = doc.createElement(xml_password_el);
ePwd.setTextContent(password);
Element child = doc.createElementNS(xml_namespaceUR_att,
xml_authentication_el);
child.appendChild(eSysId);
child.appendChild(eUserId);
child.appendChild(ePwd);
root.appendChild(child);
XMLUtils.printDOM(root);// 只是打印xml内容到控制台,可删除
SoapHeader head = new SoapHeader(qname, root);
List<Header> headers = message.getHeaders();
headers.add(head);
}
}
四，具体调用ws的类代码
private static final String webServiceConTimeout = "6000";
private static final String webServiceRevTimeout = "6000";
。。。。。。。
HelloWorldServiceImplService hello = new HelloWorldServiceImplService();
HelloWorldService service = hello.getHelloWorldServiceImplPort();
//以上什么意思请参考：http://learning.iteye.com/admin/blogs/1333223
Client clientProxy = ClientProxy.getClient(service);//通过目标ws获取代理
//注入拦截器，getOutInterceptors代表调用服务端时触发,getInInterceptors就是被调用才触发
clientProxy.getOutInterceptors().add(ash);
// 超时时间设置
HTTPConduit http = (HTTPConduit) clientProxy.getConduit();
HTTPClientPolicy httpClientPolicy = new HTTPClientPolicy();
httpClientPolicy.setConnectionTimeout(Integer
.valueOf(webServiceConTimeout));
httpClientPolicy.setReceiveTimeout(Integer
.valueOf(webServiceRevTimeout));
httpClientPolicy.setAllowChunking(false);
http.setClient(httpClientPolicy);
//以上插入点超时设置方式
//下面这行代码是具体调用服务段的deleteTeskTask（）
CallResult cResult = service.deleteTeskTask("1223");
。
。
客户端代码到此结束
五，还有一种方式是通过JaxWsProxyFactoryBean方式，注册拦截器及实例化ws,代码如下：
private static final JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
AddSoapHeader ash = new AddSoapHeader();
ArrayList list = new ArrayList();
// 添加soap header 信息
list.add(ash);
//注入拦截器，getOutInterceptors代表调用服务端时触发,getInInterceptors就是被调用才触发
factory.setOutInterceptors(list);
factory.setServiceClass(HelloWorldService.class);//实例化ws
factory.setAddress("http://xxx.xxx.xxx.xxx:8004/services/IHelloService");
Object obj = factory.create();
HelloWorldService service = (HelloWorldService) obj;
//下面这行代码是具体调用服务段的deleteTeskTask（）
CallResult cResult = service.deleteTeskTask("1223");
##########这段代码可替代步骤（四）#####
到此全部工作结束
