CXF3.0.2+Spring3.2.14 WebService入门实例三

好了，继续学习CXF WebService！这次学习CXF拦截器，老天开眼了，比较顺利，各位大牛，大神请飘过！不要嘲笑我等小白，不对我是老白了，因为我们不在一个频道上！首先还是要介绍一下开发工具和开发环境，jdk1.6.0_43+Tomcat6.0.29+MyEclipse10.5，没有使用Maven进行管理！

 

一、新建web工程，不要选择Java EE6.0,如果选了，会报一个错误！下面将会有介绍。

 

二、新建接口HelloWorld.java

package com.firstws.test;

 

import javax.jws.WebService;

 

@WebService

public interface HelloWorld{

public String sayHi(String name);

}

三、新建HelloWorldImpl.java

package com.firstws.test;

 

import javax.jws.WebService;

 

@WebService(endpointInterface = "com.firstws.test.HelloWorld")

public class HelloWorldImpl implements HelloWorld {

//注意此处不能写@Override,好像是jdk1.5不支持

public String sayHi(String text) {

System.out.println("sayHi方法被调用!");

return "Hello " + text;

}

 

}

四、建立服务类Server.java

package com.firstws.test;

 

import javax.xml.ws.Endpoint;

 

public class Server {

 

protected Server() throws Exception {

System.out.println("Starting Server");

HelloWorldImpl implementor = new HelloWorldImpl();

String address = "http://localhost:8080/wbInter";

Endpoint.publish(address,implementor);

}

 

public static void main(String args[]) throws Exception {

new Server();

System.out.println("Server ready...");

 

Thread.sleep(5 * 60 * 1000);

System.out.println("Server exiting");

System.exit(0);

}

}

五、点击运行Server.java，如果新建web工程，你选择的是Java EE5.0,那么控制台将出现如下信息

Starting Server

2016-1-6 9:34:47org.apache.cxf.wsdl.service.factory.ReflectionServiceFactoryBeanbuildServiceFromClass...

Server ready...

=====================================================================

如果你新建web工程是你选择的是Java EE6.0,那么控制台将报如下异常!然后网上一搜好多解决方式，巴拉巴拉，心中一万头草你妈飘过~~~,最后发现是工程中的jdk问题~~~~

Starting Server

2016-1-6 9:37:10 ...

Exception in thread"main" java.lang.NoSuchMethodError:org.slf4j.spi.LocationAwareLogger.log(Lorg/slf4j/Marker;Ljava/lang/String;ILjava/lang/String;[Ljava/lang/Object;Ljava/lang/Throwable;)V

atcom.firstws.test.Server.<init>(Server.java:11)

atcom.firstws.test.Server.main(Server.java:15)

 

 

六、建立一个拦截器测试类InterceperTest.java

package com.firstws.interceptor;

 

importorg.apache.cxf.interceptor.LoggingInInterceptor;

importorg.apache.cxf.interceptor.LoggingOutInterceptor;

importorg.apache.cxf.jaxws.JaxWsProxyFactoryBean;

 

import com.firstws.test.HelloWorld;

 

public class InterceperTest {

 

publicstatic void main(String[] args) {

JaxWsProxyFactoryBeanfactory = new JaxWsProxyFactoryBean();

factory.setServiceClass(HelloWorld.class);

factory.setAddress("http://localhost:8080/wbInter/HelloWorld");

factory.getInInterceptors().add(newLoggingInInterceptor());

factory.getOutInterceptors().add(newLoggingOutInterceptor());

 

HelloWorldhw = (HelloWorld) factory.create();

Stringresult = hw.sayHi("abc");

System.out.println("haaha=="+result);

}

 

}

七、点击运行InterceperTest.java

信息: Outbound Message

---------------------------

ID: 1

Address:http://localhost:8080/wb2/HelloWorld

Encoding: UTF-8

Http-Method: POST

Content-Type: text/xml

Payload: <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><ns2:sayHixmlns:ns2="http://test.firstws.com/"><arg0>abc</arg0></ns2:sayHi></soap:Body></soap:Envelope>

--------------------------------------

2016-1-6 9:41:18org.apache.cxf.services.HelloWorldService.HelloWorldPort.HelloWorld

--------------------------------------

haaha==Hello abc

 

 

八、有些时候我们需要自定义一个拦截器，做一些特殊的处理！新建一个实现类

MessageInterceptor.java

 

package com.firstws.interceptor;

 

importorg.apache.cxf.interceptor.Fault;

 

importorg.apache.cxf.message.Message;

importorg.apache.cxf.phase.AbstractPhaseInterceptor;

 

/**

* 功能：自定义消息拦截器

* 作者：张述飞

* 创建日期:2015-12-31 9:55

* qq:361202421

* 版本:V1.0

*/

 

 

Public class MessageInterceptorextends AbstractPhaseInterceptor<Message> {

 

publicMessageInterceptor(String phase) {

super(phase);

}

 

publicvoid handleMessage(Message message) throws Fault {

System.out.println("###########handlerMessage############");

System.out.println(message);

if(message.getDestination() != null) {

System.out.println(message.getId()+ "##" +message.getDestination().getMessageObserver());

}

 

if(message.getExchange() != null) {

System.out.println(message.getExchange().getInMessage()+ "##" +message.getExchange().getInFaultMessage());

System.out.println(message.getExchange().getOutMessage()+ "##" +message.getExchange().getOutFaultMessage());

}

}

 

}

 

九、新建发布类DeployInteceptorClient.java

package com.firstws.interceptor;

 

importorg.apache.cxf.jaxws.JaxWsServerFactoryBean;

importorg.apache.cxf.phase.Phase;

 

importcom.firstws.test.HelloWorld;

importcom.firstws.test.HelloWorldImpl;

 

public class DeployInteceptorClient{

 

publicstatic void main(String[] args) throws Exception {

 

JaxWsServerFactoryBeanfactory = new JaxWsServerFactoryBean();

factory.setServiceClass(HelloWorld.class);

factory.setAddress("http://localhost:8080/wbInter/HelloWorld");

factory.setServiceBean(newHelloWorldImpl());

 

factory.getInInterceptors().add(newMessageInterceptor(Phase.RECEIVE));

factory.getOutInterceptors().add(newMessageInterceptor(Phase.SEND));

 

factory.create();

 

System.out.println("Serverstart ~~~~~");

Thread.sleep(5*1000*60);

System.exit(0);

System.out.println("Serverexit~~~");

 

 

}

 

}

十、运行DeployInteceptorClient.java,运行结果为

Server start ~~~~~

十一、 新建HelloWorldServiceClient.java类

package com.firstws.interceptor;

 

import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;

 

importcom.firstws.test.HelloWorld;

 

public classHelloWorldServiceClient {

 

/**

* @param args

*/

publicstatic void main(String[] args) {

JaxWsProxyFactoryBeanclient = new JaxWsProxyFactoryBean();

client.setServiceClass(HelloWorld.class);

client.setAddress("http://localhost:8080/wbInter/HelloWorld");

 

HelloWorldservice = (HelloWorld) client.create();

System.out.println("[result]"+service.sayHi("张述飞"));

}

 

}

十二、 运行HelloWorldServiceClient.java,客户端运行结果为

[result]Hello 张述飞

 

服务端运行结果是

Server start ~~~~~

###########handlerMessage############

{org.apache.cxf.message.Message.PROTOCOL_HEADERS={Accept=[*/*],Cache-Control=[no-cache], connection=[keep-alive], Content-Length=[191],content-type=[text/xml; charset=UTF-8],

~~~~~

Content-Type=text/xml;charset=UTF-8}##null

null##null

sayHi方法被调用!

###########handlerMessage############

{javax.xml.ws.wsdl.port={http://test.firstws.com/}HelloWorldPort,org.apache.cxf.ws.policy.EffectivePolicy=org.apache.cxf.ws.policy.EffectivePolicyImpl@151ac10,

 

org.apache.cxf.service.model.BindingMessageInfo=org.apache.cxf.service.model.BindingMessageInfo@f77511,Content-Type=text/xml, org.apache.cxf.message.Message.RESPONSE_CODE=200,org.apache.cxf.headers.Header.list=[]}##null

 

=====================================================================

 

到这里为止，基本上的拦截器已经做完了，下面这部分将是和Spring嵌套使用了！！

十三、 下面这部分引用的是(达拉斯母牛的CXF实战之自定义拦截器(五))，博客地址：http://blog.csdn.net/accountwcx/article/details/47147831

在这里先谢谢他的分享！！如果侵犯了你的权益，请告诉我，我撤下来！

 

十四、 权限认证拦截器处理SOAPHeader中的认证信息，客户端在发起请求时在SOAPHeader中添加认证信息，服务端在接收到请求后，校验认证信息，校验通过则继续执行，校验不通过则返回错误。

 

<!-- 认证信息格式如下 -->

<auth xmlns="http://localhost:8080/auth">

<name>admin</name>

<password>admin</password>

</auth>

十五、 客户端代码AuthAddInterceptor.java

package com.firstws.spring;

 

import java.util.List;

 

import javax.xml.namespace.QName;

 

importorg.apache.cxf.binding.soap.SoapMessage;

importorg.apache.cxf.headers.Header;

importorg.apache.cxf.helpers.DOMUtils;

importorg.apache.cxf.interceptor.Fault;

importorg.apache.cxf.phase.AbstractPhaseInterceptor;

importorg.apache.cxf.phase.Phase;

import org.w3c.dom.Document;

import org.w3c.dom.Element;

 

public class AuthAddInterceptorextends AbstractPhaseInterceptor<SoapMessage> {

 

publicAuthAddInterceptor() {

super(Phase.PREPARE_SEND);

}

 

publicvoid handleMessage(SoapMessage message) throws Fault {

List<Header>headers = message.getHeaders();

Documentdoc = DOMUtils.createDocument();

Elementauth = doc.createElementNS("http://zhangshufei/auth","auth");

 

Elementname = doc.createElement("name");

name.setTextContent("admin");

 

Elementpassword = doc.createElement("password");

password.setTextContent("admin");

 

auth.appendChild(name);

auth.appendChild(password);

 

headers.add(newHeader(new QName(""),auth));

}

 

}

 

十六、 验证代码AuthValidateInterceptor.java

package com.firstws.spring;

 

import java.util.List;

 

import javax.xml.namespace.QName;

 

importorg.apache.cxf.binding.soap.SoapMessage;

importorg.apache.cxf.headers.Header;

import org.apache.cxf.interceptor.Fault;

importorg.apache.cxf.phase.AbstractPhaseInterceptor;

importorg.apache.cxf.phase.Phase;

import org.w3c.dom.Element;

import org.w3c.dom.NodeList;

 

public classAuthValidateInterceptor extends AbstractPhaseInterceptor<SoapMessage> {

 

publicAuthValidateInterceptor() {

super(Phase.PRE_INVOKE);

}

 

publicvoid handleMessage(SoapMessage message) throws Fault {

System.out.println("哈哈开始验证了！");

List<Header>headers = message.getHeaders();

 

if(headers == null || headers.size() < 1) {

thrownew Fault(new Exception("无授权信息!"));

}

Elementauth = null;

 

for(Header header : headers) {

QNameqname = header.getName();

Stringns = qname.getNamespaceURI();

StringtagName = qname.getLocalPart();

if(ns != null && ns.equals("http://zhangshufei/auth")&& tagName != null && tagName.equals("auth")) {

auth= (Element)header.getObject();

break;

}

}

 

if(auth == null) {

thrownew Fault(new Exception("无授权信息！"));

}

 

NodeListnameList = auth.getElementsByTagName("name");

NodeListpwdList = auth.getElementsByTagName("password");

if(nameList.getLength() != 1 || pwdList.getLength() != 1) {

thrownew Fault(new Exception("授权信息错误！"));

}

 

Stringname = nameList.item(0).getTextContent();

Stringpassword = pwdList.item(0).getTextContent();

 

if(!"admin".equals(name) || !"admin".equals(password)) {

thrownew Fault(new Exception("授权信息错误！"));

}

}

}

十七、 applicationContext.xml

package com.firstws.spring;

 

importorg.apache.cxf.interceptor.LoggingInInterceptor;

importorg.apache.cxf.interceptor.LoggingOutInterceptor;

importorg.apache.cxf.jaxws.JaxWsProxyFactoryBean;

 

import com.firstws.test.HelloWorld;

 

public class InterceperSpringTest{

 

publicstatic void main(String[] args) {

JaxWsProxyFactoryBeanfactory = new JaxWsProxyFactoryBean();

HelloWorldhw = (HelloWorld) factory.create();

Stringresult = hw.sayHi("张述飞");

System.out.println("终于出来了=="+result);

}

 

}

 

=====================================================================

这里注意先要启动Tomcat服务器，再运行InterceperSpringTest，在服务器端会显示

--------------------------------------

终于出来了==Hello 张述飞

 

====================================================================

最后注意一个错误

org.apache.cxf.interceptor.Fault:Could not send Message.

atorg.apache.cxf.interceptor.MessageSenderInterceptor$MessageSenderEndingInterceptor.handleMessage(MessageSenderInterceptor.java:64)

~~~~~~~

这个有可能是没有启动Tomcat，或者

factory.setAddress("http://localhost:8080/wbInter/HelloWorld”)的地址写的不对！！

 

好了，到这里为止，CXF自定义拦截器已经做出来了，另外吐槽一下CSDN的博客发布，能不能直接导入word格式的文件包括里面的图片，每次发布博客时，先在Word中写好，然后复制粘贴，最后再把图片一个个的复制出来，然后才能填加到博客中，很不友好啊！还能不能好好的玩耍了，能不能不让我们这群懒人们少动一下啊，再智能一下好吗？？？
