用xfire做web service 简要说明

        web service及web服务，是为了实现“基于web无缝集成”的目标而提出的全新概念，希望通过web服务能够实现不同的系统之间的相互调用，从而实现系统集成的平台无关系。

         web服务是一个应用程序，它为调用者提供一个能够通过web进行调用的API，使调用者能够用编程的方式通过web调用来开发应用程序。

          web服务的默认的格式是xml,封装和交换信息的默认协议是SOAP(simple object access protocol  简单对象访问协议），服务的描述语言是WSDL。

           第一步：使用myeclipse搭建环境,创建服务器端的工程,在工程的名字上右击鼠标，选择myeclipse->add xfire web  service -> next  选择 Core LIbraries 是添加服务器端的支持，HTTP CLient  是添加客户端的支持的，然后点击 finish 。

          第二步：创建服务器端的接口和实现类。

                         package com;

                          public interface IHelo {

                                     public abstract String get(String name);

                             }

                         实现类：

                            package com;

                           public class Helo implements IHelo {
                                    public String get(String name){
                                           return "hello"+name;
                                     }
                                   }

         第三步：在webServices.xml 添加如下代码:

                         <service>
                                 <name>cxdd</name>
                                 <namespace>www</namespace>
                                  <serviceClass>com.IHelo</serviceClass>
                                 <implementationClass>com.Helo</implementationClass>
                          </service>

           第四步：编写web.xml

                             <servlet>
                                  <servlet-name>XFireServlet</servlet-name>
                                          <servlet-class>org.codehaus.xfire.transport.http.XFireConfigurableServlet</servlet-class>
                                          <load-on-startup>0</load-on-startup>
                                  </servlet>
                                  <servlet-mapping>
                                              <servlet-name>XFireServlet</servlet-name>
                                              <url-pattern>/services/*</url-pattern>
                                 </servlet-mapping>

            第五步：创建客户端工程,添加xfire的,同创建服务器工程。

                          把服务器端的接口打包成jar包，添加到客户端工程中。创建一个类：                       

                                         import  org.codehaus.xfire.XFireFactory;
                                         import  org.codehaus.xfire.client.XFireProxyFactory;
                                          import  org.codehaus.xfire.service.Service;
                                           import  org.codehaus.xfire.service.binding.ObjectServiceFactory;

                                          import  com.IHelo;

                                           public class F {

                                                     public static void main(String[] args) {
                                                               Service s=new ObjectServiceFactory().create(IHelo.class);
                                                               XFireProxyFactory f=new XFireProxyFactory(XFireFactory.newInstance().getXFire());
                                                               String url="启动tomcat ,  在浏览器中输入访问服务器工程+/services/       ,在WSDL里最下面找见url  复制到此处";
                                                                           try {
                                                                                     IHelo i=(IHelo)f.create(s,url);
                                                                                     System.out.println(i.get("哈哈哈"));
                                                                              } catch (Exception e) {
   
                                                                  }
                                                           }

                                                       }

 

 好了运行程序看见 输出 “hello哈哈哈” 大功告成了
