Java Download Large File Stops Unexpectedly

I am downloading a large file (500MB to 1GB) from a java spring tomcat application.
The method below to download the file has been working great in the past, but today it started behaving weirdly. Only about the first 20MB - 50MB would get downloaded before the browser (chrome) thought the file was finished.
#RequestMapping(value = "/DownloadPDFSaved/{group}", method = RequestMethod.GET)
public void downloadGroup(#PathVariable String group, HttpServletResponse response) {
if(!StringUtils.hasText(group)) {
response.sendError(400, "Group is empty");
return;
}
InputStream is = new FileInputStream(new File(getPDFZipFilePathForGroup(group)));
IOUtils.copy(is, response.getOutputStream());
response.flushBuffer();
}
In the tomcat logs, I can see a ClientAbortException, but it doesn't give too much useful information.
Do I need to set the content length? If so, would I set the content length to the size of the file? Can you see anything else that would be causing an issue downloading a large zip file?

Adding the content-length header seems to fix the problem. I am guessing that the browser was cutting the download short without the header and that was causing the ClientAbortException.
Here is the updated and working code:
#RequestMapping(value = "/DownloadPDFSaved/{group}", method = RequestMethod.GET)
public void downloadGroup(#PathVariable String group, HttpServletResponse response) {
if(!StringUtils.hasText(group)) {
response.sendError(400, "Group is empty");
return;
}
File zipFile = new File(getPDFZipFilePathForGroup(group));
//set content-length header
response.setHeader("Content-Length", Long.toString(zipFile.length()));
InputStream is = new FileInputStream(zipFile);
IOUtils.copy(is, response.getOutputStream());
response.flushBuffer();
}

convert hibernate model into json spring mvc reponsebody

everyone.
I'm trying to convert a hibernate pojo to be a json responsebody like this:
#RequestMapping(value = "/getAdicionalesByCumplimiento/{idCumplimiento}", method = RequestMethod.GET)
public #ResponseBody
List<Adicional> getAdicionalesByCumplimiento(HttpSession session,
#PathVariable(value = "idCumplimiento") Long idCumplimiento) {
Usuario usuario = (Usuario) session.getAttribute("usuarioObject");
if (usuario != null) {
Cumplimientos cumplimientos = CumplimientoDAO.getCumplimientoById(idCumplimiento);
List<Adicional> adicionales = AdicionalDAO.getAdicionalesByCumplimiento(cumplimientos);
return adicionales;
} else {
return null;
}
}
I added the #JsonIgnoreProperties({"hibernateLazyInitializer", "handler"}) to every single pojo in my application, in order to ignore the lazy fetched attributes, set every single relationship attribute is not a real solution, it turns the code difficult for maintain.
This is the stack trace:

How to return FileSystemResource or json with Spring RestController?

I have a method to download a zip file and at the moment I use FileSystemResource to do it. The problem is with a extension controller, I ccheck if a file is really zip file and I throw an exception if isn't so.
This exception create a Json object with error details and return it.
The problem is the type of Rest api because now I have :
#RequestMapping(value = "/zipDownload", produces="application/zip", method = RequestMethod.GET)
public FileSystemResource getZip(#RequestParam(value="filePath", required=true) String filePath ) throws FileExtensionException{
return file.getZipFile(filePath);
}
and services:
public FileSystemResource getZipFile(String fileName) throws FileExtensionException {
String ext=FilenameUtils.getExtension(fileName);
if (!ext.equals("zip"))
throw new FileExtensionException(ext + " and not zip");
return new FileSystemResource(new File(fileName));
}
the exception
public class FileExtensionException extends Exception {
private static final long serialVersionUID = 1L;
public FileExtensionException(String message){
super("The selected file has a different extension:" + message);
}
}
and exception controller
#ControllerAdvice
public class ErrorController {
/**
*
* #param e: exception thrown
* #return ErroreResponse
*/
#ExceptionHandler(value = Exception.class)
public #ResponseBody ErrorResponse errorHandler(Exception e){
//Make the exception by buildErrorResponse
return ErrorResponseBuilder.buildErrorResponse(e);
}
}
The problem another exception launched by Spring that override mine:
2015-09-21 09:09:05.197 ERROR 7500 --- [nio-8080-exec-2] .m.m.a.ExceptionHandlerExceptionResolver : Failed to invoke

How can I return Zip file or json message in the same method? the problem is , produces="application/zip", without this recieve the correct error json but it doesn't download the file, otherwise vice versa
Thanks

EDIT
You can keep your getZip from your controller as is and just change your #ExceptionHandler this way :
#ExceptionHandler(Exception.class)
#ResponseStatus(HttpStatus.BAD_REQUEST)
public #ResponseBody ErrorResponse errorHandler(Exception e, HttpServletRequest request) {
request.setAttribute(HandlerMapping.PRODUCIBLE_MEDIA_TYPES_ATTRIBUTE, Collections.singleton(MediaType.APPLICATION_JSON));
return ErrorResponseBuilder.buildErrorResponse(e);
}
Here I just modify the request and reset the PRODUCIBLE_MEDIA_TYPES_ATTRIBUTE parameter to tell explicitly to Spring what representation I want to use.

Exception with Spring ExceptionHandler and Rest response

I'm using #ExceptionHandler to manage all my exception and to return a JSON response for any REST API that throws exception.
At the moment I manage two exception, the first is ResourceNotFoundException and it works but the second, FileExtensionException, it doesn't work.
It throws this exception in eclipse console and nothing into rest response.

Where is the problem?

Try to update your spring configuration with:
<bean id="methodHandlerExceptionResolver" class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerExceptionResolver">
<property name="messageConverters">
<list>
<ref bean="stringHttpMessageConverter"/>
<ref bean="jsonHttpMessageConverter"/>
<ref bean="marshallingHttpMessageConverter"/>
</list>
</property>
</bean>

In home.jsp, you are accessing the modal attribute display. but from controller you are not passing display attribute.
#RequestMapping("/index")
private String InitPage(Model map) {
System.out.println("Entered index page");
map.addAttribute("display", new Display());
return "home";
}

You can follow anyone of the below ways:
#RequestMapping(value = "/login", method = RequestMethod.GET)
public String displayLogin(Login loginModel) {
return "login";
}
or
#RequestMapping(value = "/login", method = RequestMethod.GET)
public String displayLogin(Model model) {
model.addAttribute("login", new Login());
return "login";
}

Add this to your controller:
#ModelAttribute("login")
public Login blabla() {
return new Login();
}
