Java -将html转换为pdf

Question

我希望将一个HTMLdocument转换成一个PDF文件。为此，我没有问题地将我的文档从HTML转换为.docx。要将它从.docx转换为PDF，我遵循以下链接：Converting docx into pdf in java

但我有个错误：

线程“org.apache.poi.POIXMLDocumentPart.getPackageRelationship()Lorg/apache/poi/openxml4j/opc/PackageRelationship；应用程序线程”中的异常java.lang.NoSuchMethodError: java.lang.NoSuchMethodError

我使用的是POI版本3.17的库。

Answer 1

当使用ApachePOIVersion3.10-Final设计/构建转换库时，会引发异常。
