我想将docx转换为html。我开始编写与github中给出的示例相同的代码。这只是加载部分。但在那里,我遇到了问题。
import org.docx4j.Docx4J;
import org.docx4j.openpackaging.exceptions.Docx4JException;
import org.docx4j.openpackaging.packages.WordprocessingMLPackage;
public class Main {
public static void main(String[] args) throws Docx4JException,
String inputfilepath = "myfilepathhere";
OutputStream os = new FileOutputStream(inputfilepath + ".html");
WordprocessingMLPackage wordMLPackage = Docx4J
.load(new FileInputStream(inputfilepath));
}
}
我遇到了NullPointerException。查看异常追踪并在Github中导航源代码后,我怀疑它与这个类相关的JAXB有关,该类是https://github.com/plutext/docx4j/blob/master/src/main/java/org/docx4j/jaxb/Context.java。
Docx4j源代码可在https://github.com/plutext/docx4j上找到。
异常追踪:

这个docx文档很好(由Word 2010创建)。我甚至解压它,看看Content_Types.xml是否存在。它在那里。
我正在使用Eclipse和Java SE 7。我已经在项目属性中的Java构建路径中添加了所有必需的jar文件。
请帮助我。
更新:
实际上,当我将Context.java中的这行代码添加到我的类中以查看是否是问题所在时。
JAXBContext.newInstance("org.docx4j.openpackaging.contenttype");
我在控制台中看到以下异常:
Exception in thread "main" javax.xml.bind.JAXBException: Provider org.eclipse.persistence.jaxb.JAXBContextFactory not found
