篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了基于Myeclipse+Axis2的WebService开发实录相关的知识，希望对你有一定的参考价值。

　　最近开始学习了下在Myeclipse开发工具下基于WebSerivce的开发，下面将相关相关关键信息予以记录

Myeclipse的安装，本文以Myeclipse2014-blue为开发环境，相关配置执行完善
从http://archive.apache.org/dist/ws/axis2/tools/下载Axis2包,下载 axis2-eclipse-codegen-wizard.zip,下载axis2-eclipse-service-archiver-wizard.zip
从http://axis.apache.org/axis2/java/core/download.html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)
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
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
下面借助于axis2来开发webservice
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

axis2配置代码如下：

    <!-- 加载Axis2 -->  
	<servlet>  
		<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>

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表示您的WebService服务名 -->
<service name="HelloWorld" >
    <!-- HelloWorld表示您的WebService服务描述 -->
    <description>  
          HelloWorld  Service Example   
    </description>  
    <!-- 这个必须是这个服务的类路径 -->
    <parameter name="ServiceClass">      
        cn.homily.action.HelloWorld
    </parameter>  
    <!-- 这个是这个服务的方法名 -->
    <operation name="getHello">    
        <messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />    
    </operation>    
    <operation name="getWorld">    
        <messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />    
    </operation>    
    <operation name="getHelloWorld">    
	<!-- 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-->  
        <messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />    
    </operation> 
</service>

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
{
　　//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。

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http://zgc-20150226yxm: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：
