　　最近開始學習了下在Myeclipse開發工具下基於WebSerivce的開發，下面將相關相關關鍵資訊予以記錄

1. Myeclipse的安裝，本文以Myeclipse2014-blue為開發環境，相關配置執行完善
2. 從http://archive.apache.org/dist/ws/axis2/tools/下載Axis2包,下載 axis2-eclipse-codegen-wizard.zip,下載axis2-eclipse-service-archiver-wizard.zip
3. 從http://axis.apache.org/axis2/java/core/download.html下載(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. 下載說明：從步驟1下載出來的Axis2_Codegen_Wizard_1.3.0檔案夾，Axis2_Service_Archiver_1.3.0檔案夾拷貝到myeclipse安裝目錄之dropins檔案下，重啟myeclipse下載到的axis2-1.7.0-war.zip，拷貝檔案之tomact/webapps目錄下面,重新命名axis2.war,重新整理檔案夾，tomact為解壓該部署套件，此時可以通過tomact服務訪問axis2站，看到相關頁面表示成功
5. 在步驟4中，注意檔案夾axis2\WEB-INF，下面有3個檔案夾，conf，modules，services,lib檔案夾，稍後我們會用到
6. 下面藉助於axis2來開發webservice
7. 開啟myeclipse建立web project項目，將步驟5中conf，modules，services,lib檔案夾的拷貝之WebRoot/WEB-INF/下面,並在WEB-INF下面建立Web.xml檔案，倘若web.xml存在則開啟，添加以下代碼配置axis2
8. axis2配置代碼如下：

       <!-- 載入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> 

   　　

9. 在WEB-INF/services/下建立Axis2Service/META-INF/目錄，建立檔案services.xml,添加如下webservice服務配置代碼

       <!-- HelloWorld表示您的WebService服務名 --><service name="HelloWorld" >    <!-- HelloWorld表示您的WebService服務描述 -->    <description>            HelloWorld  Service Example       </description>      <!-- 這個必須是這個服務的類路徑 -->    <parameter name="ServiceClass">              cn.homily.action.HelloWorld    </parameter>      <!-- 這個是這個服務的方法名 -->    <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">    <!-- 這裡要注意，當沒有傳回值時才用   org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver，沒有參數還是用RPCMessageReceiver-->          <messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />        </operation> </service>

   　　

10. 在src包下面添加子包cn.homily.action，添加HelloWorld.java檔案,其代碼如下：

    package cn.homily.action;//服務名public class HelloWorld{
    　　//服務方法    public String getHello(String name)    {        return "Hello， " + name + ".";    }    //服務方法    public String getWorld(String name)    {        return "World," + name + ".";    }    //服務方法    public String getHelloWorld()    {        return "Hello,World";    }}

    　　經過以上步驟，我們的WebService基本代碼已經全了，現在看看實際效果。

11. 現在打包我們的Web-Project，部署我們的Web-Project至tomact,現在我們運行，在瀏覽器輸入如下地址http://zgc-20150226yxm:8080/sayHello2Axis/services/HelloWorld?wsdl。如果在瀏覽器裡面看到了以下代碼，說明我們的Web-Service服務Demo開發完成。正確的頁面效果如下：
