CXF-01: WebService的第一个例子

HelloWorld.java:

 package com.war3.ws;

 import javax.jws.WebService;

 @WebService
 public interface HelloWorld {

     String sayHi(String name);
 }

HelloWorldWS.java:

 package com.war3.ws.impl;

 import javax.jws.WebService;
 import com.war3.ws.HelloWorld;

 @WebService(endpointInterface="com.war3.ws.HelloWorld")
 public class HelloWorldWS implements HelloWorld {

     @Override
     public String sayHi(String name) {
         return name+",你好！";
     }

 }

ServerMain.java:

 package com.war3.ws.server;

 import javax.xml.ws.Endpoint;

 import com.war3.ws.HelloWorld;
 import com.war3.ws.impl.HelloWorldWS;

 public class ServerMain {

     public static void main(String[] args) {
         HelloWorld hw = new HelloWorldWS();
         Endpoint.publish("http://localhost:8080/hello", hw);
         System.out.println("WebService暴露服务成功!");
     }
 }

运行ServerMain.java,控制台打印"WebService暴露服务成功!"。

浏览器输入：http://localhost:8080/hello?wsdl，回车得到：

 <wsdl:definitions xmlns:ns1="http://ws.war3.com/" xmlns:ns2="http://schemas.xmlsoap.org/wsdl/soap/http" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://impl.ws.war3.com/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" name="HelloWorldWSService" targetNamespace="http://impl.ws.war3.com/">
 <wsdl:import location="http://localhost:8080/hello?wsdl=HelloWorld.wsdl" namespace="http://ws.war3.com/"></wsdl:import>
 <wsdl:binding name="HelloWorldWSServiceSoapBinding" type="ns1:HelloWorld">
 <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
 <wsdl:operation name="sayHi">
 <soap:operation soapAction="" style="document"/>
 <wsdl:input name="sayHi">
 <soap:body use="literal"/>
 </wsdl:input>
 <wsdl:output name="sayHiResponse">
 <soap:body use="literal"/>
 </wsdl:output>
 </wsdl:operation>
 </wsdl:binding>
 <wsdl:service name="HelloWorldWSService">
 <wsdl:port binding="tns:HelloWorldWSServiceSoapBinding" name="HelloWorldWSPort">
 <soap:address location="http://localhost:8080/hello"/>
 </wsdl:port>
 </wsdl:service>
 </wsdl:definitions>

然后我们再新建一个Java工程WebService_Client：

利用wsdl2java命令和wsdlurl参数，我们在src目录下生成了一些代码：

然后我们写一个类ClientMain.java:

 package com.war3.ws.client;

 import com.war3.ws.HelloWorld;
 import com.war3.ws.impl.HelloWorldWSService;

 public class ClientMain {

     public static void main(String[] args) {
         HelloWorldWSService factory = new HelloWorldWSService();
         HelloWorld hw = factory.getHelloWorldWSPort();
         System.out.println(hw.sayHi("tom"));
     }
 }

运行代码，控制台输出“tom,你好！”。
