Java6开发WebService入门

[align=center]Java6开发WebService入门[/align]

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。
