我已经完成了同样问题的答案,但是 Struts 中没有任何默认方法可以防止重新提交吗?另外,就我而言,如果我确实重置了表单字段,它仍然会保存旧值(但它如何获取这些值)?
我有一个调度动作类:
public class QrcAction extends DispatchAction
{
public ActionForward waiverPage( final ActionMapping inMapping,
final ActionForm inForm,
final HttpServletRequest inRequest,
final HttpServletResponse inResponse )
{
QrcForm qrcForm = (QrcForm) inForm;
if ( StringUtils.isEmpty( qrcForm.getCustomerId() ) )
{
ActionMessages errors = getErrors( inRequest );
errors.add( IAppConstants.APP_ERROR, new ActionMessage( IPropertiesConstant.ERROR_INVALID_CUSTOMER_ID ) );
saveErrors( inRequest, errors );
return inMapping.findForward( IActionForwardConstant.QRC_SEARCH_CUSTOMER_PAGE );
}
qrcForm.setCustWaiverPojo( new CrmCustWaiverPojo() );
qrcForm.setRemarksPojo( new RemarksPojo() );
return inMapping.findForward( IActionForwardConstant.WAIVER_PAGE );
}
public ActionForward applyWaiver( final ActionMapping inMapping,
final ActionForm inForm,
final HttpServletRequest inRequest,
final HttpServletResponse inResponse )
{
String forward = IActionForwardConstant.WAIVER_PAGE;
QrcForm qrcForm = (QrcForm) inForm;
ActionMessages messages = getMessages( inRequest );
ActionMessages errors = getErrors( inRequest );
CrmuserDetailsDto userDto = (CrmuserDetailsDto) inRequest.getSession( false )
.getAttribute( IAppConstants.CRM_USER_OBJECT );
double waiverLimit = 0;
if ( StringUtils.isNotEmpty( userDto.getWaiverLimitAmmount() ) )
waiverLimit = Double.parseDouble( userDto.getWaiverLimitAmmount() );
if ( waiverLimit < qrcForm.getCustWaiverPojo().getWaiverAmount().doubleValue() )
{
errors.add( IAppConstants.APP_ERROR, new ActionMessage( IPropertiesConstant.ERROR_INVALID_WAIVER_LIMIT,
waiverLimit ) );
}
QrcFormHelper.validateWaiver( errors, qrcForm ); // validates pojo fields
if ( errors.isEmpty() )
{
// saving data to database
if ( success )
{
messages.add( IAppConstants.APP_MESSAGE, new ActionMessage( "success.msg.key" ) );
// resetting the form fields
qrcForm.setCustWaiverPojo( new CrmCustWaiverPojo() );
qrcForm.setRemarksPojo( new RemarksPojo() );
qrcForm.setSrTicketNo( null );
}
else
errors.add( IAppConstants.APP_ERROR, new ActionMessage( "error.msg.key" ) );
}
saveErrors( inRequest, errors );
saveMessages( inRequest, messages );
return inMapping.findForward( forward );
}
}
被waiverPage()
调用以显示表单并提交给applyWaiver()
. 在applyWaiver()
成功保存值时,我正在重置表单字段并将其转发到同一页面。提交并成功后,将显示一条消息并清除表单,然后如果我再次刷新它,请使用相同的先前值在 db 中输入。
这个问题有什么解决办法吗?
