我正在開發一個大型應用程序，我們在代理中使用了Mavem bundle插件，以使它變得更小！導入一些需要的庫來處理PDFbox所需的某些圖像（jpeg2000和jbig2）時遇到問題。帶有Maven bundle插件的OSGi不加載庫
這裏是我的聚甲醛（一部分）

我固定的導入包和我沒有這些警告了！

這是我的方法，其中pdfBox使用這些庫我在try/catch塊中得到一個異常！
private static boolean checkPDFImagesSize(PDDocument document) {
PDPageTree list = document.getPages();
PDXObject o;
for (PDPage page : list) {
PDResources pdResources = page.getResources();
for (COSName cosName : pdResources.getXObjectNames()) {
try {
o = pdResources.getXObject(cosName);
} catch (IOException e) {
throw ProxyRuntimeException.of(ExceptionCodes.ERROR_GENERATING_PDF_IMAGES);
}
if (o instanceof org.apache.pdfbox.pdmodel.graphics.image.PDImageXObject) {
if (((PDImageXObject) o).getHeight() * ((PDImageXObject) o).getWidth() * ((PDImageXObject) o)
.getBitsPerComponent() * 3.0 > ALERT_IMAGE_SIZE_INSIDE_PDF) {
return false;
}
}
}
}
return true;
}
當的IntelliJ調試運行我得到這個！
org.apache.pdfbox.filter.MissingImageReaderException：無法讀取JPEG2000圖像：Java高級圖像（JAI）圖像I/O工具未安裝
在Apache Felix Console（'/ system/console/bundles'）中是否有任何導入錯誤？您在清單中定義的進口是否滿意？ – Jens
我在哪裏可以檢查！？但是我不會在編譯時遇到任何錯誤，但是在運行時，我得到了這個異常！ :( – PcS
你可以在http：//：/system/console/bundles找到的Apache Felix控制檯中檢查，你可以點擊這個包來查看是否可以導入所有需要的類。不是它會顯示給你，看看這個問題中的圖像，它應該看起來很像這樣：http://stackoverflow.com/q/43242977/190823你可能有一個非常類似的問題 –
