篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了servlet3.0以后无需在web.xml中配置servlet相关的知识，希望对你有一定的参考价值。
//下面这句话代替了web.xml中对servlet的配置
@WebServlet("/Upload")
public class Upload extends HttpServlet {
private static final long serialVersionUID = 1L;
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doPost(request, response);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
//该段是用servlet输出页面
response.setContentType("text/html;charset=GBK");
PrintWriter out = response.getWriter();
out.println("<HTML>");
out.println("<HEAD><TITLE>firstse</TITLE></HEAD>");
out.println("<BODY>");
out.print("这是servlet");
out.println("</BODY>");
out.println("</HTML>");
}
}
