CXF 入门实例

先去Apache下载cxf的最新jar包  本人的是 2.3.0

将所有jar加载到类路径下

 

然后：

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

定义一个接口

 

 package com.cxf.service.iface;

 import javax.jws.WebParam;
 import javax.jws.WebService;

 @WebService
 public interface Helloworld {
     public String sayHello(@WebParam(name="text") String text);
 }

 

定义一个实现

 package com.cxf.service.impl;

 import javax.jws.WebService;

 import com.cxf.service.iface.Helloworld;

 @WebService(serviceName="Helloworld")
 public class HelloworldImpl implements Helloworld {

     public String sayHello(String text) {
         return "hello " + text;
     }

 }

 

第三步： 发布web service 服务

 

 package com.cxf.service.app;

 import javax.xml.ws.Endpoint;

 import com.cxf.service.impl.HelloworldImpl;

 public class HelloworldService {

     /**
      * @param args
      */
     public static void main(String[] args) {
         HelloworldImpl implementor = new HelloworldImpl();
         String address = "http://localhost:9000/MyService";
         Endpoint.publish(address, implementor);
         System.out.println("服务已经发布....");
     }

 }

 

 

打开浏览器 输入http://localhost:9000/MyService?wsdl

 

   <?xml version="1.0" encoding="UTF-8" ?>
 - <wsdl:definitions name="Helloworld" targetNamespace="http://impl.service.cxf.com/" xmlns:ns1="http://iface.service.cxf.com/" xmlns:ns2="http://schemas.xmlsoap.org/soap/http" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://impl.service.cxf.com/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <wsdl:import location="http://localhost:9000/MyService?wsdl=Helloworld.wsdl" namespace="http://iface.service.cxf.com/" />
 - <wsdl:binding name="HelloworldSoapBinding" type="ns1:Helloworld">
   <soap:binding style="document" mce_style="document" transport="http://schemas.xmlsoap.org/soap/http" />
 - <wsdl:operation name="sayHello">
   <soap:operation soapAction="" style="document" mce_style="document" />
 - <wsdl:input name="sayHello">
   <soap:body use="literal" />
   </wsdl:input>
 - <wsdl:output name="sayHelloResponse">
   <soap:body use="literal" />
   </wsdl:output>
   </wsdl:operation>
   </wsdl:binding>
 - <wsdl:service name="Helloworld">
 - <wsdl:port binding="tns:HelloworldSoapBinding" name="HelloworldImplPort">
   <soap:address location="http://localhost:9000/MyService" />
   </wsdl:port>
   </wsdl:service>
   </wsdl:definitions>

 

 

抓取有用的信息。。。。

 

wsdl:definitions name="Helloworld".....

 <wsdl:import location="http://localhost:9000/MyService?wsdl=Helloworld.wsdl"namespace="http://iface.service.cxf.com/" />

targetNamespace="http://impl.service.cxf.com/

 

 

客户端调用

 package com.cxf.client;

 import javax.xml.namespace.QName;
 import javax.xml.ws.Service;
 import javax.xml.ws.soap.SOAPBinding;

 import com.cxf.service.iface.Helloworld;

 public class HelloworldClient {
     //  http://impl.service.cxf.com/
     private static String namespaceURI = "http://iface.service.cxf.com/";
     private static QName SERVICE_NAME = new QName(namespaceURI, "Helloworld");
     private static QName PORT_NAME = new QName(namespaceURI,"HelloworldPort");
     /**
      * @param args
      */
     public static void main(String[] args) {
         Service service = Service.create(SERVICE_NAME);
         String endpointAddress = "http://localhost:9000/MyService";
         service.addPort(PORT_NAME, SOAPBinding.SOAP11HTTP_BINDING, endpointAddress);
         Helloworld hw = service.getPort(Helloworld.class);
         String info = hw.sayHello("涛哥");
         System.out.println(info);
     }

 }

 

注意几点：

1：namespaceURI指的是targetNamespace！

2：PORT_NAME  的第二个参数 是 服务名 + port

而不是<wsdl:port binding="tns:HelloworldSoapBinding" name="HelloworldImplPort">
中的 HelloworldImplPort  这点不是很懂。 先记着就ok

3： 如果namespaceURI SERVICE_NAME PORT_NAME 配置错误， 将会抛出一个

Invalid address. Endpoint address cannot be null.

 

另外 namespaceURI  末尾有一个反斜杠 /

 

4：endpointAddress 区分大小写 。 否则将会抛出一个404
