获取输入 num Sessions

Question

我想通过 Sessions 获取输入 num。为了获得确切输入的数量，到目前为止我有代码

protected void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    // TODO Auto-generated method stub

    String pro=request.getParameter("inputs");
    HttpSession session=request.getSession(true);
    Integer Counter =
               (Integer)session.getAttribute("Counter");
    session.setAttribute("input", inp);
    if(Counter==null){
         Counter=0;
        println((String)session.getAttribute("input") +""+Counter);
    }
    if((session.getAttribute("input").equals(inp))){
        Counter++;
        println(session.getAttribute("input")+"" +Counter);
    }

Answer 1

我会做一些类似的事情：

public void doPost(HttpServletRequest request, HttpServletResponse response) {
    String word = request.getParameter("word");

    HttpSession httpSession = request.getSession();

    Integer numRequestsForWord = (Integer)httpSession.getAttribute(word);

    if( numRequestsForWord == null )
        numRequestsForWord = 1;
    else
        numRequestsForWord += 1;

    httpSession.setAttribute(word, numRequestsForWord);

    if( numRequestsForWord == 1 )
        System.out.println( word );
    else
        System.out.println( word + "(" + numRequestsForWord + ")");
}

这需要一个 POST - 我不确定你是如何调用这个方法的。
