Primefaces + SpringBoot大文件上传失败

Question

虽然简单，但却无法正常工作

upload.xhtml

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

方法

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());
    }

我的环境是

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