JSP学习笔记(一百二十三)：使用axis1.4开发webservice应用(二)

通过上篇文章，已经可以通过axis1.4发布服务以及调用服务了，不过上篇文章发布服务使用的方法不够灵活，这里介绍一种灵活的方式

一、以Stubs的方式发布服务

1.以这种方式发布还需要两个J2EE包

activation.jar

mail.jar

2.修改web.xml，我使用了struts2，和axis的配置会有冲突，为了避免冲突，对struts2的相关配置也做了对应修改，这里贴出完整web.xml文件内容：

<?xml version= "1.0" encoding= "UTF-8" ?>
<web-app id= "WebApp_ID" version= "2.4"
    xmlns= "http://java.sun.com/xml/ns/j2ee" xmlns:xsi= "http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation= "http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" >
    <display-name> static </display-name>
    <filter>
        <filter-name>struts2</filter-name>
        <filter- class >org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter- class >
    </filter>
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>*.action</url-pattern>
    </filter-mapping>
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/struts/dojo/*</url-pattern>
    </filter-mapping>

    <servlet>
        <servlet-name>AxisServlet</servlet-name>
        <servlet- class >org.apache.axis.transport.http.AxisServlet</servlet- class >
    </servlet>
    <servlet-mapping>
        <servlet-name>AxisServlet</servlet-name>
        <url-pattern>/servlet/AxisServlet</url-pattern>
    </servlet-mapping>
    <servlet-mapping>
        <servlet-name>AxisServlet</servlet-name>
        <url-pattern>/services/*</url-pattern>
    </servlet-mapping>

    <welcome-file-list>
        <welcome-file>index.htm</welcome-file>
    </welcome-file-list>
</web-app>

3.编写服务类 com.site.webservice.MyService.java

package com.site.webservice;

public class MyService{
    public String getName(String name)
    {
        return "hi," + name;
    }
}

4.在项目WEB-INF目录下创建deploy.wsdd文件，内容为：

<deployment xmlns= "http://xml.apache.org/axis/wsdd/"
    xmlns:java= "http://xml.apache.org/axis/wsdd/providers/java" >
    <service name= "MyService" provider= "java:RPC" >
        <parameter name= "className" value= "com.site.webservice.MyService" />
        <parameter name= "allowedMethods" value= "*" />
    </service>
</deployment>

5.在项目WEB-INF目录下创建deploy.bat文件，内容为：

set Axis_Lib=D:\workspace\proj1\WebContent\WEB-INF\lib
set Java_Cmd=java -Djava.ext.dirs=%Axis_Lib%
set Axis_Servlet=http: //localhost:8080/proj1/servlet/AxisServlet
%Java_Cmd% org.apache.axis.client.AdminClient -l%Axis_Servlet% deploy.wsdd

dos下进入D:\workspace\proj1\WebContent\WEB-INF目录，执行deploy.bat，执行成功后会提示：

Processing file deploy.wsdd
<Admin>Done processing</Admin>

通过http://localhost:8080/proj1/services可以检查服务是否发布成功

6.编写客户端代码调用我们创建的服务：

String endPoint = "http://localhost:8080/proj1/services/MyService" ;
Service service = new Service();
Call call = (Call)service.createCall();
call.setOperationName( new QName(endPoint, "getName" ));
call.setTargetEndpointAddress( new URL(endPoint));
String result = (String)call.invoke( new Object[]{ "abcd" });
System.out.println(result);

执行该代码打印内容为：hi,abcd

7.如果需要卸载MyService服务，在WEB-INF目录下创建undeploy.wsdd文件：

<undeployment xmlns= "http://xml.apache.org/axis/wsdd/" >
 <service name= "MyService" />
</undeployment>

在WEB-INF目录下创建undeploy.bat文件：

set Axis_Lib=D:\workspace\proj1\WebContent\WEB-INF\lib
set Java_Cmd=java -Djava.ext.dirs=%Axis_Lib%
set Axis_Servlet=http: //localhost:8080/proj1/servlet/AxisServlet
%Java_Cmd% org.apache.axis.client.AdminClient -l%Axis_Servlet% undeploy.wsdd

dos下进入D:\workspace\proj1\WebContent\WEB-INF目录，执行undeploy.bat，MyService服务就被卸载了

二、以Stubs的方式调用服务

 
1、在WEB-INF目录下创建client.bat文件：

set Axis_Lib=D:\workspace\proj1\WebContent\WEB-INF\lib
set Java_Cmd=java -Djava.ext.dirs=%Axis_Lib%
set Output_Path=D:\workspace\proj1\src
set Package=com.site.client
%Java_Cmd% org.apache.axis.wsdl.WSDL2Java -o%Output_Path% -p%Package% http: //localhost:8080/proj1/services/MyService?wsdl

dos下进入D:\workspace\proj1\WebContent\WEB-INF目录，执行client.bat，会在com.site.client下自动生成如下文件类：

MyServiceSoapBindingStub.java

SayHello.java

SayHelloService.java

SayHelloServiceLocator.java

2、客户端调用

SayHelloService service = new SayHelloServiceLocator();
SayHello client = service.getMyService() ;
String result = client.getName( "abcdefg" );
System.out.println(result);
