File upload Primefaces文件上载不适用于文件大小>；1Mb。

我上传大于1mb的文件时遇到问题。不会调用FileUploadEvent，因为较小的文件正常工作

我正在使用； commons-fileupload-1.2.2 commons-io-2.3 primefaces-4.0

jsf 2.2

上传的文件保存在

D

驱动器中。它起作用了

使用以下代码更新

handleFileUpload

方法

public void handleFileUpload(FileUploadEvent event) {
    try {
        UploadedFile file = event.getFile();
        InputStream inputStream = file.getInputstream();
        OutputStream outputStream = new FileOutputStream("D:/"+ file.getFileName());
        byte[] bytes = file.getContents();
        int read = 0;
        while ((read = inputStream.read(bytes)) != -1 ) {
            outputStream.write(bytes, 0, read);
        }
        inputStream.close();
        outputStream.flush();
        outputStream.close();

    } catch (Exception e) {
        e.printStackTrace();
    }
}

我会在两年后给你答案。。。英雄联盟 更改web服务器中的“最大帖子大小”。 如果您使用玻璃鱼： 配置->网络配置->列表器->http->最大帖子大小

这个问题困扰了我三个月
