Java6開發WebService入門

←手機掃碼閱讀     火星人 @ 2014-03-09 , reply:0

  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中已經支持用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,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;
  /**
  * Java6開發WebService入門
  *
  * @author leizhimin 2009-11-13 16:10:44
  */
  @WebService
  public class Java6WebService {
  /**
  * Web服務中的業務方法
  *
  * @return 一個字元串
  */
  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());
  }
  }

  運行后,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" ?>

</service>
</definitions>

  可見,Java6開發WebService也是很方便的.
