为JSpinner创建自定义例外

我有两个JSpinner组件，我为其创建了一个自定义异常并且工作得很好。昨天我修改了Netbeans中的微调，我添加了一个微调模型编辑器，因为我只想要正数。为JSpinner创建自定义例外

所以现在我只有正数，但是当我把-1这样的东西不像以前那样显示错误信息，为什么？

这里是我的代码：

public int getAlerte() { 
     int res = 0; 

     if (Integer.parseInt(jSpinnerTime.getValue().toString()) <= 0 || 
      Integer.parseInt(jSpinnerTime.getValue().toString()) >1000) { 
      JOptionPane.showMessageDialog(this, "Time should be between 1 and 1000", 
        "Alert", JOptionPane.ERROR_MESSAGE); 
      res = 1; 
     }  
     if (res == 0){ 
      int visperiod = Integer.parseInt(jSpinnerTime.getValue().toString())/2;    
      if (Integer.parseInt(jSpinnerFreqV.getValue().toString()) <= 0 || 
       Integer.parseInt(jSpinnerFreqV.getValue().toString()) > visperiod){ 
       JOptionPane.showMessageDialog(this, "Visualization frequency should be between 1 and "+visperiod, 
        "Alert", JOptionPane.ERROR_MESSAGE); 
      res = 1; 
      } 

     } 
     return res; 
    }

为什么不直接使用['int'基于'SpinnerNumberModel']（http://docs.oracle.com/javase/7/docs/api/javax/swing/SpinnerNumberModel.html#SpinnerNumberModel%28int,%20int ，％20int，％20int％29）与4 x'int'的适当值？ –

为了尽快提供更好的帮助，请发布[SSCCE]（http://sscce.org/）。 –

这就是SpinnerNumberModel中的用法。确定下次SSCCE会使用它，谢谢 – Pan24112012

我试过SSCCE，我希望它有用的你，这里是代码：

    public JPanelPolyg() { 
    initComponents(); 
     jListParameter.setModel(rc.getModel()); 
    jListParameter.setCellRenderer(new SimpleRenderer()); 
    jSpinnerEnters.setValue(150); 

    } 

    public JPanelPoly(Frame parent,int nbrCenter, int nbrParameter){

问题是：当我输入-1或如果单击“确定”而不在jSpinner中输入任何内容，它将不会显示错误消息。

我试图将我的getAlert（）放在代码的开头，并且它不起作用。谢谢 – Pan24112012
