在Wildfly上使用Primefaces Fileupload

Question

我想在数据库中保存配置文件图像.

页:

<p:graphicImage id="profileImage"
                        value="#{myProfile.usersProfileImage}" />    
<p:fileUpload fileUploadListener="#{myProfile.fileUploadListener}"
                            auto="true" mode="advanced" update="profileImage"
                            sizeLimit="100000" allowTypes="/(\.|\/)(gif|jpe?g|png)$/" />

后盾:

public StreamedContent getUsersProfileImage() {
            return new DefaultStreamedContent(new ByteArrayInputStream(
                    user.getProfileJpegImage()));
    }    
public void fileUploadListener(FileUploadEvent event) {
        try {
            setProfileImageFromInputStream(event.getFile().getInputstream());
        } catch (IOException e) {
            throw new IllegalStateException(e);
        }
    }

    private void setProfileImageFromInputStream(InputStream stream) {
        try {
            user.setProfileJpegImage(IOUtils.toByteArray(stream));
        } catch (IOException e) {
            throw new IllegalStateException(e);
        }
    }

选择图片后,图片不会改变,我的控制台出现以下错误

14:36:02,387 ERROR [io.undertow.request] (default task-2) UT005005: Cannot remove uploaded file C:\Development\wildfly-8.0.0.Final\standalone\tmp\myApp.war\undertow3307538071115388117upload

我也发现了这个问题 https://issues.jboss.org/browse/WFLY-2329

我还尝试使用multipart-config来扩展我的Faces Servlet,例如:

<servlet>
        <servlet-name>Faces Servlet</servlet-name>
        <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
        <multipart-config>
            <max-file-size>20848820</max-file-size>
            <max-request-size>418018841</max-request-size>
            <file-size-threshold>1048576</file-size-threshold>
        </multipart-config>
    </servlet>

但没有改变.

有任何想法吗？TY先进

我得到了同样的错误:

[io.undertow.request] (default task-62) UT005005: Cannot remove uploaded file...

但是我可以通过在阅读后关闭流来解决这个问题.

这是我的一大堆代码(它有点不同):

    byte[] bytes;
    try {
        InputStream is = upFile.getInputstream();
        if (is != null) {
            bytes  = IOUtils.toByteArray(is);
            is.close();
        } else {
            bytes = new byte[0];
        }
    } catch (IOException e) {
        log.error(e.getMessage());
        bytes = new byte[0];
    }

添加行后:

    is.close();

udertow错误UT005005消失了.
