我正在尝试在仪表板中显示我的自定义注册缩略图，但是在检查变压器日志时，我看到了

pdf 的拇指是 0 字节，我不知道为什么。我没有收到关于缩略图 bean 本身的任何错误。以下是我对缩略图 bean 的上下文定义：

<bean id="pdfThumbnailDefinitionDoclib" class="fr.test.thumbnails.CustomThumbnailBootsrap" depends-on="ThumbnailService" init-method="init">
    <property name="thumbnailService" ref="ThumbnailService" />
    <property name="thumbnailDefinitions">
        <list>
            <bean class="org.alfresco.repo.thumbnail.ThumbnailDefinition">
                    <property name="name" value="pdfThumbs" />
                    <property name="mimetype" value="image/png"/>
                    <property name="transformationOptions">
                            <bean class="org.alfresco.repo.content.transform.magick.ImageTransformationOptions">
                                    <property name="resizeOptions">
                                            <bean class="org.alfresco.repo.content.transform.magick.ImageResizeOptions">

                                                    <property name="width" value="210" />
                                                    <property name="maintainAspectRatio" value="true"/>
                                                    <property name="resizeToThumbnail" value="false" />
                                            </bean>
                                    </property>
                            </bean>
                    </property>
                    <property name="runAs" value="System"/>
                    <property name="placeHolderResourcePath" value="alfresco/extension/thumbnail/thumbnail_placeholder_scImageThumbnail.png" />
            </bean>
        </list> 
    </property>
</bean>

该代码主要改编自 jpotts ecma 网站（ http://ecmarchitect.com/archives/2009/03/03/913链接不允许）。所以java bean是一个like for like copy，除了类名和包
