Question

我上传大于1mb的文件有问题，没有调用FileUploadEvent，因为较小的文件正常工作。

Web.xml中：

<filter>
    <filter-name>PrimeFaces FileUpload Filter</filter-name>
    <filter-class>org.primefaces.webapp.filter.FileUploadFilter</filter-class>
    <init-param>
        <param-name>thresholdSize</param-name>
        <param-value>52428800</param-value>
    </init-param>
    <init-param>
        <param-name>uploadDirectory</param-name>
        <param-value>D:\</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>PrimeFaces FileUpload Filter</filter-name>
    <servlet-name>Faces Servlet</servlet-name>
</filter-mapping>

ManagedBean：

 @ManagedBean
@RequestScoped
public class TesteUpload {

    public void handleFileUpload(FileUploadEvent event) {
        UploadedFile uploadedFile = event.getFile();
        File file = new File(PropertiesLoader.getInstance().getPropertie(PropertiesLoader.PATCH_MIDIA), uploadedFile.getFileName());

        try {
            FileOutputStream fileOutputStream = new FileOutputStream(file);
            byte[] buffer = new byte[6124];
            int bulk;
            InputStream inputStream = event.getFile().getInputstream();
            while (true) {
                bulk = inputStream.read(buffer);
                if (bulk < 0) {
                    break;
                }
                fileOutputStream.write(buffer, 0, bulk);
                fileOutputStream.flush();
            }
        } catch (IOException e) {
            e.printStackTrace();
            FacesMessage error = new FacesMessage("Erro!!");
            FacesContext.getCurrentInstance().addMessage(null, error);
        }
    }
}

2年后，我会给你答案......哈哈更改Web服务器中的“最大发布大小”。如果您使用Glassfish：配置 - ＆gt;网络配置 - ＆gt; listner - ＆gt; http - ＆gt; “最大邮政大小”

这个问题困扰了我3个月。

上传的文件保存在D驱动器中。它有效。

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();
    }
}

Primefaces fileUpload无法使用文件大小＆gt; 1MB。
