javax.xml.transform.TransformerException：com.sun.org.apache.xml.internal.utils.WrappedRuntimeException：連接超時：連接

我想使用XSLT轉換xml。我的xml在xml doctype中有「https」的dtd文件的url。如果我刪除這個文檔類型，我可以轉換文件，但與文檔類型我得到以下錯誤。javax.xml.transform.TransformerException：com.sun.org.apache.xml.internal.utils.WrappedRuntimeException：連接超時：連接

我無法刪除這種在實際場景中的文檔類型。請幫忙。

您正在收到錯誤，因爲解析器正在Web上解析DOCTYPE中URL處的DTD。此提取失敗。

您需要在本地存儲DTD，並使用EntityResolver來使用本地副本。

看到這個問題和頂部的答案，看看如何做到這一點。 Prevent DTD download when using XSLT i.e. XML Transformer

感謝@Alohci，它正在工作，但無論如何，我們可以忽略dtd下載和驗證？在我的活動場景中，我可以接收多種XML，並且無法在本地保留並跟蹤所有xml的dtd。 – 2013-03-04 14:46:05

如果您在entityResolver與該URL匹配時返回空字符串，那麼實際上不會進行驗證，您也不必在本地保留DTD的副本。如果在DTD中定義了任何實體，顯然你會失去這些信息。 – Alohci 2013-03-04 15:35:18

它的工作原理，感謝@Alohci的幫助 – 2013-03-06 06:22:29
