Usage

From source file:org.springframework.web.servlet.mvc.generic.GenericFormController.java

/**
 * This implementation calls {@link #showForm} in case of errors,
 * and delegates to  {@link #onSubmit}'s variant else.
 * <p>This can only be overridden to check for an action that should be executed
 * without respect to binding errors, like a cancel action. To just handle successful
 * submissions without binding errors, override the {@link #onSubmit} method.
 * @see #showForm/*from  w w  w.ja v  a 2s.co  m*/
 * @see #onSubmit
 */
protected ModelAndView processFormSubmission(HttpServletRequest request) throws Exception {
    T formObject = formBackingObject(request);
