以下是使用CXF Apache的插件实现Web Service的一个简单入门实例





1========新建一个服务接口



package com.clark;



import javax.jws.WebParam;

import javax.jws.WebService;



@WebService

public interface IHelloWorld {

    

    public String sayHello(@WebParam(name="name")String name);

    

    public int plus(int a,int b);

}

2========服务接口实现类



package com.clark.impl;



import com.clark.IHelloWorld;



public class HelloWorldImpl implements IHelloWorld {



    @Override

    public String sayHello(String name) {

        return "Hello Wolrd ,"+name;

    }



    @Override

    public int plus(int a, int b) {

        return a+b;

    }



}



3============服务端



package com.clark.service;



import javax.xml.ws.Endpoint;



import com.clark.impl.HelloWorldImpl;



public class WebServiceApp {

    public static void main(String[] args) {

        System.out.println("web service start");

        HelloWorldImpl implementor = new HelloWorldImpl();

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

        Endpoint.publish(address, implementor);

        System.out.println("web service started");

    }

}



4============client(以下主要是针对Java普通程序的)

package com.clark.client;



import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;



import com.clark.IHelloWorld;



public class HelloWorldClient {

    public static void main(String[] args) {

        JaxWsProxyFactoryBean svr = new JaxWsProxyFactoryBean();

        svr.setServiceClass(IHelloWorld.class);

        svr.setAddress("http://localhost:8080/CXFWebService/service/IHelloWorld");

        IHelloWorld hw = (IHelloWorld) svr.create();

        String name = hw.sayHello(" CXF Apache implements Web Service");

        int result = hw.plus(2, 3);

        System.out.println(name);

        System.out.println(result);

    }

}



4==============client(针对Spring中集成Web Service的Web开发)

package com.clark.web;



import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;



import com.clark.IHelloWorld;



public class HelloWorldClient {

    public static void main(String[] args) {

        System.out.println("Web Service start..........");

        ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");

        

        IHelloWorld helloWorld = (IHelloWorld)context.getBean("client");

        

        String name = helloWorld.sayHello("1111111111");

        int result = helloWorld.plus(3, 4);

        System.out.println(name+"  "+result);

        

        System.out.println("Web Service end..........");

    }

}



5============Spring 的 applicationContext.xml配置

<?xml version="1.0" encoding="UTF-8"?

>

<beans xmlns="http://www.springframework.org/schema/beans"

                 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

                 xmlns:jaxws="http://cxf.apache.org/jaxws"

                 xsi:schemaLocation="

                       http://www.springframework.org/schema/beans



                       http://www.springframework.org/schema/beans/spring-beans.xsd

                       http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">



    <jaxws:endpoint

                              id="helloWorld"

                              implementor="com.clark.impl.HelloWorldImpl"

                              address="/IHelloWorld" />

   

                <bean id="client" class="com.clark.IHelloWorld"

                           factory-bean="clientFactory" factory-method="create"/>

    

                 <bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">

                            <property name="serviceClass" value="com.clark.IHelloWorld"/>

                            <property name="address"



                                              value="http://localhost:8080/CXFWebService/service/IHelloWorld"/>

                  </bean>

</beans>



6=============Spring中集成Web Service服务(CXF Servlet的配置)，web.xml

<?

xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

  <display-name>CXFWebService</display-name>

  <welcome-file-list>

    <welcome-file>index.html</welcome-file>

    <welcome-file>index.htm</welcome-file>

    <welcome-file>index.jsp</welcome-file>

    <welcome-file>default.html</welcome-file>

    <welcome-file>default.htm</welcome-file>

    <welcome-file>default.jsp</welcome-file>

  </welcome-file-list>

 

  <context-param>

      <param-name>contextConfigLocation</param-name>

      <!-- <param-value>classpath:applicationContext.xml</param-value> -->

      <param-value>WEB-INF/applicationContext.xml</param-value>

  </context-param>

 

  <listener>

      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

  </listener>

 

  <servlet>

                     <servlet-name>CXFServlet</servlet-name>

                     <display-name>CXFServlet</display-name>

                     <servlet-class>

                            org.apache.cxf.transport.servlet.CXFServlet

                     </servlet-class>

                     <load-on-startup>1</load-on-startup>

               </servlet>



               <servlet-mapping>

                      <servlet-name>CXFServlet</servlet-name>

                      <url-pattern>/service/*</url-pattern>

               </servlet-mapping>

</web-app>



7=============启动服务，地址栏输入

http://localhost:8080/CXFWebService/service/IHelloWorld?

wsdl可以看到对应的SOAP协议在规格OK
