servlet

一、servlet的创建

• 1、继承servlet-api.jar包内的HttpServlet类即可。

  eg:

  public class StoreServlet extends HttpServlet{
     private static final long serialVersionUID = 1L;
     @Override
     protected void service(HttpServletRequest request, HttpServletResponse response) 
         throws ServletException, IOException {
       // TODO Auto-generated method stub
       super.service(request, response);
     }
  }

• 2、private static final long serialVersionUID = 1L;的作用：

  作用：防止类对象冲突，给类的对象编号。
