Java6开发WebService入门

之前常常用CXF、Axis2、XFire等来开发结合Java语言来开发Web Service应用，这样的好处是用途广，灵活，另外一个重要原因是我们的生产环境是Java5。

但实际上Java6中已经支持用Java开发WebService应用了，而且很方便。这样就大大减少了项目安装部署的代价，因为选择开源的框架依赖大量第三方包，程序的尺寸倍增。

 

下面是一个Java6开发Web Service的入门例子。

 

package lavasoft;

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

/**

*/
@WebService
public class Java6WebService {
         /**
         * Web服务中的业务方法
         *
         * @return 一个字符串
         */
         public String doSomething() {
                 return "Hello Java6 WebService!";
        }

         public static void main(String[] args) {
                 //发布一个WebService
                Endpoint.publish( "http://192.168.14.117:8080/java6ws/lavasoft.Java6WebService", new Java6WebService());
        }
}

 

运行后，在浏览器中访问 http://192.168.14.117:8080/java6ws/lavasoft.Java6WebService?wsdl会得到wsdl 如下：

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

可见，Java6开发WebService也是很方便的。
