Question

我试图在alfresco中使用apache poi变换器将excel文件转换为HTML，但目前尚未成功。

In <Project-home>/src/main/amp/config/alfresco/extension/subsystems/Transformers/default/default/transformers.properties

   content.transformer.Poi.priority=70
   content.transformer.Poi.extensions.xlsx.html.supported=true

然后我设置了 log4j.logger.org.alfresco.repo.content.transform.TransformerDebug=TRACE 和 log4j.logger.org.alfresco.util.exec.RuntimeExec=TRACE ，但我在日志中看到没有调用变压器。关于转化为卓越。

编辑： Mimetypes webscript（GET /alfresco/s/mimetypes?mimetype={mimetype?}）返回

我通过创建路径XLSX =＆gt;的复杂转换管道解决了这个问题。 PDF =＆gt; HTML。我使用coolwanglu's html2pdfEX安装起来有点棘手，所以使用this script在ubuntu上安装，不要在CentOS上安装＆lt; 7因为python存在问题。至于延期：
的src /主/安培/配置/露天/扩展/子系统/变压器/默认/默认/ transformers.properties

#increase the maximum defaults allowed size
content.transformer.OpenOffice.extensions.xlsx.pdf.maxSourceSizeKBytes=5120

#disable ootb pdf->html and xlsx->html transformation path (Apparently has no effect)
content.transformer.OpenOffice.extensions.xlsx.html.supported=false
content.transformer.complex.OpenOffice.PdfBox.extensions.*.html.available=false
content.transformer.complex.OpenOffice.PdfBox.extensions.*.html.supported=false

#PDF to html transformer
content.transformer.pdf2htmlex.available=true
#content.transformer.pdf2htmlex.thresholdCount=5
#content.transformer.default.timeoutMs=180000
content.transformer.pdf2htmlex.priority=50
content.transformer.pdf2htmlex.extensions.pdf.html.supported=true
content.transformer.pdf2htmlex.extensions.pdf.html.priority=50
content.transformer.pdf2htmlex.extensions.pdf.html.maxSourceSizeKBytes=9999


#XLSX to HTML pipeline

content.transformer.complex.Xlsx.Html.available=true
content.transformer.complex.Xlsx.Html.extensions.xlsx.html.priority=30
content.transformer.complex.Xlsx.Html.extensions.xlsx.html.supported=true

    Cannot create dynamic transformer transformer.complex.Xlsx.Html as sub transformers could not be found or
    created ("*|pdf|pdf2htmlex"). Incidentally it had no effect as the transformer properties need to be in the form
    *|pdf|*; but just in case this changes with future release of alfresco we leave this here and we are able to register custom transformers with the contentTransformerRegistry on startup.

是否可以在露天使用apache POI转换？
