Grails 3 upload file limit size

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?

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

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.
