Java6開發WebService入門

Java6開發WebService入門

 

以前經常用CXF、Axis二、XFire等來開發結合Java語言來開發Web Service應用，這樣的好處是用途廣，靈活，另一個重要緣由是咱們的生產環境是Java5。

但實際上Java6中已經支持用Java開發WebService應用了，並且很方便。這樣就大大減小了項目安裝部署的代價，由於選擇開源的框架依賴大量第三方包，程序的尺寸倍增。

 

下面是一個Java6開發Web Service的入門例子。

 

package lavasoft;

import javax.jws.WebService;
import javax.xml.ws.Endpoint;

/**

*/
@WebService
public class Java6WebService {
         /**
         * Web服務中的業務方法
         *
         * @return 一個字符串
         */
         public String doSomething() {
                 return "Hello Java6 WebService!";
        }

         public static void main(String[] args) {
                 //發佈一個WebService
                Endpoint.publish( "http://192.168.14.117:8080/java6ws/lavasoft.Java6WebService", new Java6WebService());
        }
}

 

運行後，在瀏覽器中訪問 http://192.168.14.117:8080/java6ws/lavasoft.Java6WebService?wsdl會獲得wsdl 以下：

<? xml version ="1.0" encoding ="UTF-8" ?>

可見，Java6開發WebService也是很方便的。
