背景：

????? 运行在两台独立服务器上的两个web服务，其中一个web服务需要访问另一个web服务的业务方法。但是两个服务各自的运行环境不同，一个服务运行在jdk1.5上(服务端)，使用spring2.5.6框架管理bean，而另一个运行在jdk1.4环境下(客户端)。现在要求通过webservice技术让客户端能访问服务端提供的webservice服务。

方案：

???? 服务端因为使用了spring，故使用Apache CXF框架将业务bean的方法发布为webservice服务?，客户端使用支持jdk1.4的Axis2-1.4.1，生成服务端业务方法的客户端存根，提供客户端使用。

备注：此方案对保证服务安全尚未有良好解决方案，对安全有要求请不要参考！

环境

?IDE:Eclipse3.5

?服务端：jdk1.5?，?CXF2.2.4 (http://cxf.apache.org/download.html )，?spring2.5.6 ，Tomcat6.0

?客户端：jdk1.4 ， Axis2-1.4.1( http://ws.apache.org/axis2/download/1_4_1/download.cgi )

?代码生成工具：axis2-eclipse-codegen-wizard.zip和axis2-eclipse-service-archiver-wizard.zip,下载地址http://apache.justdn.org/ws/axis2/tools/1_4_1/

服务端：

?发布一个webservice服务，

?1.jar包，参考如下图片

?2.实体类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.服务类和接口定义

接口?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") //注意此处一定要指明List元素类型 public abstract List<Person> getPersonList(); }

类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

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

?5.cxf配置文件

4.web.xml配置CXFServlet

5.测试服务端

?启动Tomcat，在浏览器地址栏输入：http://localhost:8080/CXFService/services ，看到如下页面

?点击链接进入，可以查看服务的wsdl

wsdl

至此服务发布成功！

客户端：（这里客户端只用java工程进行测试，web工程同理）

1.建立一个java project 命名为CxfServiceClient(如果需要在jdk1.4下运行，请将编译级别改为jdk1.4，否则忽略)

2.生成客户端代码

按照以下操作步骤进行：

选择Axis2 Code Generator，将PersonService的wsdl地址拷贝到以下输入框：

选择如下的参数：

继续点击Next，进入如下窗口，选择客户端工程根路径为代码生成路径，选择Axis2的lib导入到客户端工程(可选的步骤)：

最后finish：

如果生成代码报错，请在插件中lib下加入stax-api-1.0.1.jar和backport-util-concurrent-3.1.jar,检查plugin.xml是否配置这两项，然后重启eclipse

代码生成完毕，这时会发现代码上有错误提示，原因是axis2的jar包还没有引入，将CxfServiceClient/lib下的jar包引入classpath即可解决此错误。

可以发现，针对List的数据类型，Axis2实际上是生成了ArrayOfPerson的类，将List转换成了对象数组进行处理！

3.写测试用例执行测试

?在生成的测试代码上完善测试逻辑，将生成的test包拖拽到src下，完成两个测试方法的代码，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); }

执行测试，报错，

解决方案：将生成的CxfServiceClient/resources/schemaorg_apache_xmlbeans拷贝到class编译路径下，我这里是bin目录下，如图，

再执行，提示成功！
