javax.xml.transform.TransformerException：com.sun.org.apache.xml.internal.utils.WrappedRuntimeException：连接超时：连接

我想使用XSLT转换xml。我的xml在xml doctype中有“https”的dtd文件的url。如果我删除这个文档类型，我可以转换文件，但与文档类型我得到以下错误。javax.xml.transform.TransformerException：com.sun.org.apache.xml.internal.utils.WrappedRuntimeException：连接超时：连接

我无法删除这种在实际场景中的文档类型。请帮忙。

您正在收到错误，因为解析器正在Web上解析DOCTYPE中URL处的DTD。此提取失败。

您需要在本地存储DTD，并使用EntityResolver来使用本地副本。

看到这个问题和顶部的答案，看看如何做到这一点。 Prevent DTD download when using XSLT i.e. XML Transformer

感谢@Alohci，它正在工作，但无论如何，我们可以忽略dtd下载和验证？在我的活动场景中，我可以接收多种XML，并且无法在本地保留并跟踪所有xml的dtd。 – 2013-03-04 14:46:05

如果您在entityResolver与该URL匹配时返回空字符串，那么实际上不会进行验证，您也不必在本地保留DTD的副本。如果在DTD中定义了任何实体，显然你会失去这些信息。 – Alohci 2013-03-04 15:35:18

它的工作原理，感谢@Alohci的帮助 – 2013-03-06 06:22:29
