I use Stripes 1.5beta and the bug
http://stripesframework.org/jira/browse/STS-402 still happens.
Using Ben hack to handle the FileUploadLimitExceededException:
public Resolution handle(FileUploadLimitExceededException exception,
HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
/*
* This is a hack from Ben Gunter received in the Stripes forum. It is
related to Jira issue:
* http://stripes.mc4j.org/jira/browse/STS-402. The problem is that when
the exception handler is called, it
* always receives the original request passed to the StripesFilter and
not the wrapped request. That prevents
* construction of the FlashScope in which we need to store the error
message.
*/
// start of hack
// wrap the request without handling multipart data
StripesRequestWrapper wrapper = new StripesRequestWrapper(request) {
/**
* Ignore multipart content and set the locale at the same time.
*
* @param request the HTTP request to wrap.
*/
@Override
protected void constructMultipartWrapper(HttpServletRequest request)
throws StripesServletException {
Locale locale =
StripesFilter.getConfiguration().getLocalePicker().pickLocale(request);
setLocale(locale);
}
};
// end of hack
// get referer URL
URL referer = null;
try {
referer = new URL(request.getHeader("referer"));
} catch (Exception e) {
throw exception;
}
// convert referer path to context-relative path
String path = referer.getFile();
String contextPath = request.getContextPath();
if (contextPath.length() > 0) {
if (!path.startsWith(contextPath + "/"))
throw exception;
path = path.replace(contextPath, "");
}
// create action bean and context
Configuration config = StripesFilter.getConfiguration();
PVoucherActionBeanContext context = (MyActionBeanContext)
config.getActionBeanContextFactory()
.getContextInstance(request, response);
ActionBean actionBean =
config.getActionResolver().getActionBean(context);
// try to guess the field name
String fieldName = ValidationErrors.GLOBAL_ERROR;
try {
BeanInfo beanInfo = Introspector.getBeanInfo(actionBean.getClass());
for (PropertyDescriptor pd : beanInfo.getPropertyDescriptors()) {
if (pd.getPropertyType().equals(FileBean.class)) {
fieldName = pd.getName();
break;
}
}
} catch (Throwable t) {
}
// add validation error
DecimalFormat format = new DecimalFormat("0.00");
double max = (double) exception.getMaximum() / 1024;
double posted = (double) exception.getPosted() / 1024;
context.getValidationErrors().add(fieldName,
new LocalizableError("error.file.too.large", format.format(max),
format.format(posted)));
// redirect back to referer
return new RedirectResolution(path).flash(actionBean);
}
still crashes when flashing the action bean!
Isn't there a better way to handle this exception with Stripes 1.5?
Cheers,
Samuel
