用axis开发webservice实践

axis开发webservice实践

李俊杰

什么是SOAP
SOAP
是一个基于XML的用于应用程序之间通信数据编码的传输协议。最初由微软和Userland Software提出,随着不断地完善和改进,SOAP很快被业界广泛应用。

什么是Axis?
Axis
本质上就是一个SOAP引擎,提供创建服务器端、客户端和网关SOAP操作的基本框架。Axis目前版本是为Java编写的,不过为C++的版本正在开发中。

配置webservice具体步骤:

1.     安装weblogic

2.     配置一个web应用,如“\\lijunjie\e$\software\bea\user_projects\domains\lijjdomain\applications\ cntapws “。

3.         apache网站上下载axis-bin-1_2_1.tar.gz,解压后copycntapws下面。

4.         打开“http://localhost:7001/console“,配置cntapws web应用。

5.         axis1.2weblogic8.1有冲突,原因是weblogic 本身携带的webservice.jar使用的旧的javax.xml.soap.*,而不是像axis使用J2EE1.4新的版本。解决方案是在WEB-INF/weblogic.xml文件中如下的配置:

    <weblogic-web-app>

 <container-descriptor>

  <prefer-web-inf-classes>true</prefer-web-inf-classes>

</container-descriptor>

</weblogic-web-app>

 

6.         http://localhost:8080/axis/happyaxis.jsp地址,可以显示你发布的webservice是否配置成功,如果显示必须的包缺失,则你的webservice不能正常运行。

开发webservice流程

1.         写普通的java类,该类中有你要发布到webservice上的有关方法。

2.         配置server-comfig.xml, 把你要发布的方法写入该文件。具体内容如下:

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

<deployment xmlns="http://xml.apache.org/axis/wsdd/" xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">

 <globalConfiguration>

  <parameter name="adminPassword" value="admin"/>

  <parameter name="attachments.Directory" value="C:\eclipse\workspace\bookstore\WEB-INF\attachments"/>

  <parameter name="attachments.implementation" value="org.apache.axis.attachments.AttachmentsImpl"/>

  <parameter name="sendXsiTypes" value="true"/>

  <parameter name="sendMultiRefs" value="true"/>

  <parameter name="sendXMLDeclaration" value="true"/>

  <parameter name="axis.sendMinimizedElements" value="true"/>

    <parameter name="scope" value="session"/>

   </handler>

   <handler type="java:org.apache.axis.handlers.JWSHandler">

    <parameter name="scope" value="request"/>

    <parameter name="extension" value=".jwr"/>

   </handler>

  </requestFlow>

 </globalConfiguration>

 <handler name="LocalResponder" type="java:org.apache.axis.transport.local.LocalResponder"/>

 <handler name="Authenticate" type="java:org.apache.axis.handlers.SimpleAuthenticationHandler"/>

 <handler name="URLMapper" type="java:org.apache.axis.handlers.http.URLMapper"/>

 <service name="Version" provider="java:RPC">

  <parameter name="allowedMethods" value="getVersion"/>

  <parameter name="className" value="org.apache.axis.Version"/>

 </service>

 <--要配置的内容start,注意每一个要发布成webservice的类都要配置成一个service如下à

 <service name="webserviceproxy" provider="java:RPC">

       <parameter name="className" value="com.copia.webservice.server.proxy.WebServiceProxy"/>

       <parameter name="allowedMethods" value="*"/>

<!—具体某个方法说明-->

       <operation name="login" returnType="ns:LoginOutServiceBean">

              <parameter name="branchNo" type="xsd:string"/>

              <parameter name="userId" type="xsd:string"/>

              <parameter name="password" type="xsd:string"/>

              <parameter name="certificateNo" type="xsd:string"/>  

       </operation>

<!—如果该方法的参数有基本类型和对象类型,则不要声明,webservice能够找到相关的类及方法-->

<!—声明涉及到的所有类及其父类,引用类,还有它们的相关类,类似与对象树遍历,某个类声明缺失也会导致运行失败-->

</deployment>

3.         在地址栏输入http://localhost:7001/cntapws/services/webserviceproxy?wsdl,如没有什么错误,则表示你的webservice发布成功了。

Java  webservice客户端编程

1.         启动你配置好的weblobic

2.         进入dos界面,在你的临时目录(任意目录)下根据wsdl产生客户文件,如下指令:

E:\kk>java -Djava.ext.dirs=E:\software\bea\user_projects\domains\lijjdomain\appl

ications\axis\WEB-INF\axislib org.apache.axis.wsdl.WSDL2Java http://localhost:7001/cntapws/services/webserviceproxy?wsdl即可在kk目录下产生有关文件

3.         把产生的文件copy到你的工程中,再写一个webservice调用测试类,如下:

public class TestWs {

 

       public static void main(String[] args) {

              WebServiceProxyService service = new WebServiceProxyServiceLocator();

              try {

                     WebServiceProxy serviceProxy = service.getwebserviceproxy();

                     User user = new User();

                     user.setBranchNo("000001");

                     user.setClerkNo("1004");

                     GetBatchListInServiceBean in = new GetBatchListInServiceBean();

                     in.setCurPageNo(1);              

                     String serviceName = "GetBatchListService";

                     GetBatchListOutServiceBean out = (GetBatchListOutServiceBean)serviceProxy.getBatchListService(user, in, serviceName);

                     BatchJobDefBean[] defBeans = out.getBatchJobDefBeans();

                    for(int i = 0 ; i < defBeans.length ; i++){

                            System.out.println(defBeans[i].getBatchName());

                     }

              }catch(Exception ex){
