JSP学习札记(一百二十三)：使用axis1.4开发webservice应用(二)
拷贝自博客园--
魔豆的BLOG
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); |
