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

拷贝自博客园--

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);
