我是靠谱客的博主搞怪抽屉，最近开发中收集的这篇文章主要介绍servlet中的代码，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

	private static final long serialVersionUID = 1L;

	/**

* Constructor of the object.

*/
	public check_oka() {

super();
	}

	/**

* Destruction of the servlet. <br>

*/
	public void destroy() {

super.destroy(); // Just puts "destroy" string in log

// Put your code here
	}

	public void doGet(HttpServletRequest request, HttpServletResponse response)

throws ServletException, IOException {

	}

	/**
