Grails 3 File Upload

grailsFileUpload.groovy

// In your controller, use the following code

// Single file
def file = request.getFile("identifier_name_in_html_tag_attribute")

// Useful information
file.empty
file.class  // => class org.springframework.web.multipart.support.StandardMultipartHttpServletRequest$StandardMultipartFile
file.name  // the name attribute value you used above (comes from html input tag)
file.originalFilename
file.size
file.contentType  // e.g. "image/png"

// Multiple files
request.getFiles("pictures[]").each {
    // use closure parameter if you don't want to use "it"
    //file -> println(file.originalFilename)
    println it.originalFilename
}

// This also works:
request.multiFileMap.get("pictures[]").each {
    print it.originalFilename
}

How do you handle FileUploadBase$SizeLimitExceededException when the size is bigger than the max allowed?

Hola Pablo,

¿Conseguiste capturar la excepción en Grails 3.3.x?

@rmarquezromero no he podido porque la excepción ocurre antes de llegar a los controllers y nadie ha provisto una solución que funcione en Grails 3.
