Grails 3 upload file limit size

Question

What i am doing and what happened?

I am trying to upload files in grails and dowloand them. After make it, I am still facing a problem, when the file size is large. Here is the exception:

Caused by: org.apache.tomcat.util.http.fileupload.FileUploadBase$SizeLimitExceededException: 
the request was rejected because its size (3553808) exceeds the configured maximum (128000)

What I tryed and the result:

I found this asked before in this question, and the answer is to put some configuration variables:

grails:
    controllers:
        upload:
            maxFileSize: (10 * 1024 * 1024)
            maxRequestSize: (10 * 1024 * 1024)

But still getting the same error. I also tryed to add some dependencies as said here. Or close IDE And rebuild. And nothing could be solved.

Did someone face this issue and could solved it?

Did you try any of the other answers on the linked question, like [this bean configuration](https://stackoverflow.com/a/29857024/487033)? — doelleri, Apr 11 '18 at 14:17
I tried it again in combination with `compile group: 'commons-fileupload', name: 'commons-fileupload', version: '1.3.3'`. This solved the problem, but can't find the file in the request as before. — IgniteCoders, Apr 11 '18 at 14:32
The answer with the bean configuration also said that there is no need of any dependencies or additional configuration. — IgniteCoders, Apr 11 '18 at 14:33
Is your deployment container enforcing this limit perhaps? How are you running/deploying your application? — Daniel, Apr 11 '18 at 14:48

The problem is in the assignation of the cofig variables. I assign them without operators:

        maxFileSize: 10485760
        maxRequestSize: 10485760

Instead of:

        maxFileSize: (10 * 1024 * 1024)
        maxRequestSize: (10 * 1024 * 1024)

This is how I solved the problem.

were you able to catch the FileUploadBase$SizeLimitExceededException if the upload size is bigger than the one configured? – Pablo Pazos Jun 12 '20 at 00:27
Sorry! I don't remember the behaviour of that, more that 2 years without touching that temary :S – IgniteCoders Jun 12 '20 at 00:31

Following working fine for me with grails version 3.2 and above

We are going to allow 25MB files uploads.

25 * 1024 * 1024 = 26.214.400 bytes

My /grails-app/conf/application.yml

grails:
 controllers:
  upload:
    maxFileSize: 26214400
    maxRequestSize: 26214400

My my.gsp file

<g:form action="saveImage" enctype="multipart/form-data" method="POST">

    <input type="file" placeholder="Select file" name="file">

    <g:submitButton value="Upload File"/>

</g:form>

My controller action

def saveImage(){
def fileName = ''
def uploadedFile = request.getFile('file')

if (uploadedFile)
    if (!uploadedFile.empty) {
        try {

            int dot = uploadedFile.originalFilename.lastIndexOf('.');
            def fileExt = uploadedFile.originalFilename.substring(dot + 1);
            fileName = ("myFile." + fileExt).toString()
            def basePath = ''
            if (Environment.current == Environment.PRODUCTION) {
                basePath ='/var/local/prj/uploads/' // this works with production and tested on Ubuntu OS
            } else {
                basePath = grailsApplication.mainContext.servletContext.getRealPath('/uploads/') // this will take your project directory path Project\src\main\webapp\uploads folder
            }
            uploadedFile.transferTo(new File(basePath + fileName))
        } catch (Exception e) {
            e.printStackTrace()
        }
    }
    // Your redirect code here
}

Download file action

def file = new File("Your file path")
if (file.exists()) {
    response.setContentType("application/octet-stream") // or or image/JPEG or text/xml or whatever type the file is
    response.setHeader("Content-disposition", "attachment;filename=\"${file.name}\"")
    response.outputStream << file.bytes
} else 
    render "File does not exist!"

Hope this helps you

@IgniteCoders what is the size of file, which you are trying to upload? – Rahul Mahadik Apr 12 '18 at 11:58
I am trying to upload different size files. between 10 and 2 Mb. But i solved it finally, look at my answer. – IgniteCoders Apr 12 '18 at 12:00

I think i also mentioned same :) check `maxFileSize: 26214400 and maxRequestSize: 26214400` – Rahul Mahadik Apr 12 '18 at 12:02
Yea, but i never thought that could be the problem. Because i didnt get any error, the config just take default and skiping the mine. – IgniteCoders Apr 12 '18 at 12:06
and how to deal with exceptions if file is bigger than the limit? – Pablo Pazos Oct 15 '19 at 00:09
@PabloPazos Grails default size for file uploads is 128000 (~128KB). When this limit is exceeded you’ll see the exception: `org.springframework.web.multipart.MultipartException: Could not parse multipart servlet request; nested exception is java.lang.IllegalStateException: org.apache.tomcat.util.http.fileupload.FileUploadBase$SizeLimitExceededException` – Rahul Mahadik Oct 15 '19 at 05:43
yep, but that exception AFAIK is thrown before the controller, so where to do the catch? – Pablo Pazos Oct 15 '19 at 15:28
