org.apache.xalan.processor.TransformerFactoryImpl 上的 AbstractMethodError

Question

使用以下代码：

private Document transformDoc(Source source) throws TransformerException, IOException {
    TransformerFactory factory = TransformerFactory.newInstance();
    factory.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false);
    factory.setFeature("http://xml.org/sax/features/validation", false);

    Transformer xslTransformer =
            factory.newTransformer(new StreamSource(pdfTransformXslt.getInputStream()));
    JDOMResult result = new JDOMResult();
    xslTransformer.transform(source, result);
    return result.getDocument();
}

我收到以下错误：

java.lang.AbstractMethodError: org.apache.xalan.processor.TransformerFactoryImpl.setFeature(Ljava/lang/String;Z)V

这是为什么？

这是我的 Maven 依赖关系树：

谁能告诉我如何清除 intellij 的类路径？

这是类路径（来自 intellij 内部）

Answer 1

java.lang.AbstractMethodError< /p>

这意味着当前类路径中的 API 中声明的抽象方法在当前类路径中缺少具体实现。

org.apache.xalan.processor.TransformerFactoryImpl.setFeature(Ljava/lang/String;Z)V

这是自 Java SE 5.0。因此，此异常表明当前类路径中的 API 至少是 Java SE 5.0，并且具体实现与其不兼容。

Xalan 2.7.0 是第一个实现它的版本。因此，您在类路径中的某个位置有一个旧版本的 Xalan 版本。

如果您似乎无法在称为类路径的森林中找到它，我建议使用可以在 ZIP (JAR) 文件内部搜索的搜索工具扫描类路径覆盖的磁盘文件系统位置。我自己使用 WinRAR 来实现此目的。只需将该工具与 JAR 文件相关联，并搜索与文件名 TransformerFactoryImpl.class 匹配的文件（如有必要，包括表示包的路径）。结果应包含有关其所在 JAR 文件的信息。

Answer 2

最近遇到类似的问题，并通过从类路径中删除不必要的 xalan jar 来解决。由于所需的解析器实现存在于 rt.jar 中，但由于 xalan jar 存在，因此它引用了该实现并给了我这个问题。因此可以尝试的一种解决方案是删除 xalan 或 Xerces Jar 并进行检查。
