背景：

      執行在兩臺獨立伺服器上的兩個web服務，其中一個web服務需要訪問另一個web服務的業務方法。但是兩個服務各自的執行環境不同，一個服務執行在jdk1.5上(服務端)，使用spring2.5.6框架管理bean，而另一個執行在jdk1.4環境下(客戶端)。現在要求通過webservice技術讓客戶端能訪問服務端提供的webservice服務。

方案：

     服務端因為使用了spring，故使用Apache CXF框架將業務bean的方法釋出為webservice服務 ，客戶端使用支援jdk1.4的Axis2-1.4.1，生成服務端業務方法的客戶端存根，提供客戶端使用。

備註：此方案對保證服務安全尚未有良好解決方案，對安全有要求請不要參考！

環境

 IDE:Eclipse3.5

 程式碼生成工具：axis2-eclipse-codegen-wizard.zip和axis2-eclipse-service-archiver-wizard.zip,下載地址http://apache.justdn.org/ws/axis2/tools/1_4_1/

服務端：

 釋出一個webservice服務，

 1.jar包 ，參考如下圖片

 2.實體類Person.java

package com.webservice.entity; import java.io.Serializable; public class Person implements Serializable{ private static final long serialVersionUID = 1L; private Integer id; private String name; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } }

 3.服務類和介面定義

介面 PersonService.java

 package com.webservice.service; import java.util.List; import javax.jws.WebMethod; import javax.jws.WebService; import com.webservice.entity.Person; @WebService(targetNamespace="impl.service.webservice.com",name ="PersonService" ) public interface PersonService { /* (non-Javadoc) * @see com.sds.service.IPersonService#save() */ @WebMethod(operationName ="save") public abstract void save(String name); @WebMethod(operationName ="getPersonList") //注意此處一定要指明List元素型別 public abstract List<Person> getPersonList(); }

類PersonServiceImpl.java

 package com.webservice.service.impl; import java.util.ArrayList; import java.util.List; import javax.jws.WebService; import com.webservice.entity.Person; import com.webservice.service.PersonService; @WebService(endpointInterface = "com.webservice.service.PersonService" ) public class PersonServiceImpl implements PersonService { /* (non-Javadoc) * @see com.sds.service.IPersonService#save() */ /* (non-Javadoc) * @see com.webservice.service.IPersonService#save(java.lang.String) */ public void save(String name){ System.out.println("name:"+name+" successfully saved!"); } /* (non-Javadoc) * @see com.webservice.service.IPersonService#getPersonList() */ public List<Person> getPersonList() { List<Person> list=new ArrayList<Person>(); Person person=new Person(); person.setId(1); person.setName("jack0511"); list.add(person); person=new Person(); person.setId(2); person.setName("Lucy"); list.add(person); return list; } }

 4.bean配置

 5.cxf配置檔案

applicationContext-cxf.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans "
              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance "

          <jaxws:serviceFactory>
            <ref bean="jaxWsServiceFactoryBean"/>
          </jaxws:serviceFactory>
     </jaxws:endpoint>
 </beans>

4.web.xml配置CXFServlet

<?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 " xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd " 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">

    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
</web-app>

5.測試服務端

 點選連結進入，可以檢視服務的wsdl

至此服務釋出成功！

客戶端：（這裡客戶端只用java工程進行測試，web工程同理）

1.建立一個java project 命名為CxfServiceClient(如果需要在jdk1.4下執行，請將編譯級別改為jdk1.4，否則忽略)

2.生成客戶端程式碼

按照以下操作步驟進行：

選擇Axis2 Code Generator，將PersonService的wsdl地址拷貝到以下輸入框：

選擇如下的引數：

繼續點選Next，進入如下視窗，選擇客戶端工程根路徑為程式碼生成路徑，選擇Axis2的lib匯入到客戶端工程(可選的步驟)：

最後finish：

如果生成程式碼報錯，請在外掛中lib下加入stax-api-1.0.1.jar和backport-util-concurrent-3.1.jar,檢查plugin.xml是否配置這兩項，然後重啟eclipse

程式碼生成完畢，這時會發現程式碼上有錯誤提示，原因是axis2的jar包還沒有引入，將CxfServiceClient/lib下的jar包引入classpath即可解決此錯誤。

可以發現，針對List的資料型別，Axis2實際上是生成了ArrayOfPerson的類，將List轉換成了物件陣列進行處理！

3.寫測試用例執行測試

 在生成的測試程式碼上完善測試邏輯，將生成的test包拖拽到src下，完成兩個測試方法的程式碼，示例：

public void testgetPersonList() throws java.lang.Exception{ com.webservice.service.impl.PersonServiceImplServiceStub stub = new com.webservice.service.impl.PersonServiceImplServiceStub();//the default implementation should point to the right endpoint com.webservice.service.impl.GetPersonListDocument getPersonList8= (com.webservice.service.impl.GetPersonListDocument)getTestObject(com.webservice.service.impl.GetPersonListDocument.class); // TODO : Fill in the getPersonList8 here getPersonList8.addNewGetPersonList(); ArrayOfPerson arrayOfPerson=stub.getPersonList(getPersonList8).getGetPersonListResponse().getReturn(); Person[] persons=arrayOfPerson.getPersonArray(); if(persons!=null&&persons.length>0){ for(int i=0;i<persons.length;i++){ System.out.println("id:"+persons[i].getId()+"--------name:"+persons[i].getName()); } } } public void testsave() throws java.lang.Exception{ com.webservice.service.impl.PersonServiceImplServiceStub stub = new com.webservice.service.impl.PersonServiceImplServiceStub();//the default implementation should point to the right endpoint com.webservice.service.impl.SaveDocument save10= (com.webservice.service.impl.SaveDocument)getTestObject(com.webservice.service.impl.SaveDocument.class); save10.addNewSave(); save10.getSave().setArg0("Linda"); stub.save(save10); }

執行測試，報錯，

解決方案 ：將生成的CxfServiceClient/resources/schemaorg_apache_xmlbeans拷貝到class編譯路徑下，我這裡是bin目錄下，如圖，

再執行，提示成功！
