嘗試在JSP中提交表單時出現IllegalArgumentException

在JSP中嘗試提交表單時出現IllegalArgumentException。我試圖將這個請求路由到一個spring mvc控制器。雖然信息很清楚，但我不明白需要改變的是什麼。這裏是trace-嘗試在JSP中提交表單時出現IllegalArgumentException

你可以顯示你的控制器'onSubmitAction'方法嗎？ – fujy

我改變了參數的onSubmitMethod到異常：

protected String onSubmitAction(HttpServletRequest request, 
     HttpServletResponse response, @ModelAttribute CRequestForm command, BindingResult errors) 
     throws Exception {

和問題就解決了。
