基于Myeclipse+Axis2的WebService开发实录

日期：2020-06-14 栏目：程序人生浏览：次

2.从下载Axis2包,下载 axis2-eclipse-codegen-wizard.zip,下载axis2-eclipse-service-archiver-wizard.zip

3.从下载(axis2-1.7.0-bin.zip，axis2-1.7.0-war.zip，axis2-eclipse-codegen-plugin-1.7.0.zip，axis2-eclipse-service-plugin-1.7.0.zip)

4.下载说明：从步骤1下载出来的Axis2_Codegen_Wizard_1.3.0文件夹，Axis2_Service_Archiver_1.3.0文件夹拷贝到myeclipse安装目录之dropins文件下，重启myeclipse下载到的axis2-1.7.0-war.zip，拷贝文件之tomact/webapps目录下面,重命名axis2.war,刷新文件夹，tomact为解压该部署包，此时可以通过tomact服务访问axis2站，看到相关页面表示成功

5.在步骤4中，注意文件夹axis2\WEB-INF，下面有3个文件夹，conf，modules，services,lib文件夹，稍后我们会用到

6.下面借助于axis2来开发webservice

7.打开myeclipse新建web project项目，将步骤5中conf，modules，services,lib文件夹的拷贝之WebRoot/WEB-INF/下面,并在WEB-INF下面新建Web.xml文件，倘若web.xml存在则打开，添加以下代码配置axis2

8.axis2配置代码如下：

<servlet-name>AxisServlet</servlet-name>

<servlet-class>org.apache.axis2.transport.http.AxisServlet</servlet-class>

<load-on-startup>1</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>AxisServlet</servlet-name>

<url-pattern>/services/*</url-pattern>

</servlet-mapping>

9.在WEB-INF/services/下新建Axis2Service/META-INF/目录，新建文件services.xml,添加如下webservice服务配置代码

HelloWorld Service Example

</description>

cn.homily.action.HelloWorld

</parameter>

</operation>

</operation>

<!-- 这里要注意，当没有返回值时才用

org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver，

没有参数还是用RPCMessageReceiver-->

</operation>

</service>

10.在src包下面添加子包cn.homily.action，添加HelloWorld.java文件,其代码如下：

package cn.homily.action;

//服务名

public class HelloWorld

{<br>　　//服务方法

public String getHello(String name)

{

return "Hello， " + name + ".";

}

//服务方法

public String getWorld(String name)

{

return "World," + name + ".";

}

//服务方法

public String getHelloWorld()

{

return "Hello,World";

}

经过以上步骤，我们的WebService基本代码已经全了，现在看看实际效果。

11.现在打包我们的Web-Project，部署我们的Web-Project至tomact,现在我们运行，在浏览器输入如下地址:8080/sayHello2Axis/services/HelloWorld?wsdl。如果在浏览器里面看到了以下代码，说明我们的Web-Service服务Demo开发完成。正确的页面效果如下：
