Primefaces+SpringBoot large file upload failed

Question

As simple as it can be, but it is not working

upload.xhtml

<p:fileUpload mode="advanced" skinSimple="true" auto="true" fileUploadListener="#{upload.fileUploadListener}" />

method

public void fileUploadListener(FileUploadEvent e){
        // Get uploaded file from the FileUploadEvent
        this.file = e.getFile();
        // Print out the information of the file
        System.out.println("Uploaded File Name Is :: "+file.getFileName()+" :: Uploaded File Size :: "+file.getSize());
    }

My environment is

Sprintboot - 2.0.2 PrimeFaces 6.x Mojarra 2.3.4 PrimeFaces Extensions 6.2.4

What application server are you using? See for example https://stackoverflow.com/questions/28564683/how-to-limit-uploaded-filesize-in-tomcat-servlet — Jasper de Vries, Sep 18 '19 at 08:33
Nope, debugger point does not hit no logs no errors @Selaron — Sarz, Sep 18 '19 at 09:00
Is there an error in the javascript [console] tab? Looks like jquery wants to tell something. — Selaron, Sep 18 '19 at 09:43
Spring boot has a 1MB maximum upload by default. See: https://stackoverflow.com/questions/40271484/spring-upload-file-size-limit to change your Spring Boot config to allow bigger files. — Melloware, Sep 18 '19 at 10:36

It is not a duplicate because of "Primefaces" term in the question. Sending large files is a matter of both client and server sides. On server-side, you have to do as shown into Spring upload file size limit. On client-side (the Primefaces based "view") you have to do like shown at fileUpload component's documentation, by adding maxChunkSize attribute to your code:

<p:fileUpload mode="advanced" maxChunkSize="1000000"
              auto="true" skinSimple="true"                  
              listener="#{upload.fileUploadListener}" />
