cxf釋出webservice

準備: 新建工程 匯入需要的jar 包:

                  依賴的包:

                            commons-logging-1.1.jar
                            geronimo-activation_1.1_spec-1.0-M1.jar (or Sun's Activation jar)
                            geronimo-annotation_1.0_spec-1.1.jar (JSR 250)
                            geronimo-javamail_1.4_spec-1.0-M1.jar (or Sun's JavaMail jar)
                            geronimo-servlet_2.5_spec-1.1-M1.jar (or Sun's Servlet jar)
                            geronimo-ws-metadata_2.0_spec-1.1.1.jar (JSR 181)
                            jaxb-api-2.1.jar
                            jaxb-impl-2.1.6.jar
                            jaxws-api-2.1.jar
                            jetty-6.1.5.jar
                            jetty-util-6.1.5.jar
                            neethi-2.0.jar
                            saaj-api-1.3.jar
                            saaj-impl-1.3.jar
                            stax-api-1.0.1.jar
                            wsdl4j-1.6.1.jar
                            wstx-asl-3.2.1.jar
                            XmlSchema-1.2.jar
                            xml-resolver-1.2.jar     

                  spring jar 包, 用來支援xml配置:

                            aopalliance-1.0.jar
                            spring-core-2.0.4.jar
                            spring-beans-2.0.4.jar
                            spring-context-2.0.4.jar
                            spring-web-2.0.4.jar

                   CXF jar包:

                            cxf-2.1.jar

         以上jar 包 可從apache官方網站下載 apache-cxf-2.1.2.zip, 然後從apache-cxf-2.1.2/lib 目錄中獲得

      1  首先服務點介面。

          package com.demo;

          import java.util.List;

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

          @WebService
          public interface HelloWorld {
               String sayHi(@WebParam(name="text")String text);
               String sayHiToUser(User user);
               String[] SayHiToUserList(List<User> userList);
           }

     2  編寫服務實現

         package com.demo;

         import java.util.LinkedHashMap;
         import java.util.List;
         import java.util.Map;

         import javax.jws.WebService;

         @WebService(endpointInterface="com.demo.HelloWorld",serviceName="HelloWorld")
         public class HelloWorldImpl implements HelloWorld {
 
                    Map<Integer, User> users = new LinkedHashMap<Integer, User>();

 
                    public String sayHi(String text) {
                                return "Hello " + text;
                   }

                   public String sayHiToUser(User user) {
                             users.put(users.size()+1, user);
                             return "Hello "+ user.getName();
                   }

                   public String[] SayHiToUserList(List<User> userList) {
                             String[] result = new String[userList.size()];
                             int i=0;
                             for(User u:userList){
                                  result[i] = "Hello " + u.getName();
                                  i++;
                             }
                     return result;
                   }
       }

  3  編寫 webServiceApp.java類來暴露 web服務。

      package com.demo;

      import javax.xml.ws.Endpoint;

      public class webServiceApp {
                 public static void main(String[] args) {
                           System.out.println("web service start");
                           HelloWorldImpl implementor= new HelloWorldImpl();
                           String address="
http://localhost:8080/helloWorld";
                           Endpoint.publish(address, implementor);
                           System.out.println("web service started");
                  }
      }

     wsdl。

 5  編寫客戶端訪問服務。

     package com.demo;

     import java.util.ArrayList;
     import java.util.List;

     import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
     import org.springframework.context.support.ClassPathXmlApplicationContext;

     public class HelloWorldClient {
              public static void main(String[] args) {
                        JaxWsProxyFactoryBean svr = new JaxWsProxyFactoryBean();
                        svr.setServiceClass(HelloWorld.class);
                        svr.setAddress("
http://localhost:8080/helloWorld");
                        HelloWorld hw = (HelloWorld) svr.create();
                        User user = new User();
                        user.setName("Tony");
                        user.setDescription("test");
                        System.out.println(hw.sayHiToUser(user));
              }
     }

  6  測試: run webServiceApp.java 類來啟動服務,然後 run HelloWorldClient.java 來訪問服務。

  二 整合到spring 中。

  1 在 web.xml 中加入 :

       <?xml version="1.0" encoding="UTF-8"?>
       <web-app>
                <welcome-file-list>
                         <welcome-file>index.jsp</welcome-file>
                </welcome-file-list>


                <context-param>
                          <param-name>contextConfigLocation</param-name>
                          <param-value>WEB-INF/classes/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>/webservice/*</url-pattern>
               </servlet-mapping>
         </web-app>

2  在 applicationContext.xml 中加入:

http://www.springframework.org/schema/beans/spring-beans.xsd
http://cxf.apache.org/jaxwshttp://cxf.apache.org/schemas/jaxws.xsd">
 
                <import resource="classpath:META-INF/cxf/cxf.xml"/>
                <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml"/>
                <import resource="classpath:META-INF/cxf/cxf-servlet.xml"/>
 
                 <jaxws:endpoint 
                              id="helloWorld"
                              implementor="com.demo.HelloWorldImpl"
                              address="/helloWorld" />
   
                <bean id="client" class="com.demo.HelloWorld" 
                           factory-bean="clientFactory" factory-method="create"/>
    
                 <bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">
                            <property name="serviceClass" value="com.demo.HelloWorld"/>
                            <property name="address"

  3  修改客戶端。

      package com.demo;

     import java.util.ArrayList;
     import java.util.List;

     import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
     import org.springframework.context.support.ClassPathXmlApplicationContext;

     public class HelloWorldClient {
              public static void main(String[] args) {
                        HelloWorld client = (HelloWorld)context.getBean("client");
                        User user1 = new User();
                        user1.setName("Tony");
                        user1.setDescription("test");
                        User user2 = new User();
                        user2.setName("freeman");
                        user2.setDescription("test");
                        List<User> userList= new ArrayList<User>();
                        userList.add(user1);
                        userList.add(user2);
                        String[] res = client.SayHiToUserList(userList);
                        System.out.println(res[0]);
                        System.out.println(res[1]);          

              }
     }

  4  釋出工程 啟動web伺服器(我用 tomcat 6)。

  6  run run HelloWorldClient.java 來訪問服務。
