Java6開發WebService入門

 之前常常用CXF、Axis2、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，另外一個重要原因是我們的生產環境是Java5。但實際上Java6中已經支援用Java開發WebService應用了，而且很方便。這樣就大大減少了項目安裝部署的代價，因為選擇開源的架構依賴大量第三方包，程式的尺寸倍增。 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 一個字串
         */
        public String doSomething() {
                return "Hello Java6 WebService!";
        }

        public static void main(String[] args) {
                //發布一個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會得到wsdl 如下：<?xml version="1.0" encoding="UTF-8" ?>
