Java 为什么在尝试读取.DOCX文件时出现异常？

尝试使用以下代码段读取

.docx

文件时：

public void parseDocxFile(String textEntered) {
    try {
        XWPFDocument doc = new XWPFDocument(new FileInputStream(new File(SContainer.getFilePath())));
        XWPFWordExtractor extractor = new XWPFWordExtractor(doc);
        System.out.println("DOCX File : " + extractor.getText());
    }catch(Exception exc) {exc.printStackTrace();}
}

我得到一个例外，它说：

这是什么意思？为什么会发生这种情况？

您的类路径缺少一个库。检查POI的页面

重新分配：

你需要

poi ooxml

取决于（请参见

依赖项

标记）

poi ooxml模式取决于

因此，您必须在类路径上添加。

add

说明：

如果Java虚拟机或ClassLoader实例尝试加载类的定义（作为普通方法调用的一部分或使用新表达式创建新实例的一部分），但找不到该类的定义，则引发

---

编译当前执行的类时，已存在搜索的类定义，但无法再找到该定义。

读取和写入

docx

文件需要哪些

jar

？这很令人困惑。我在它的术语中没有添加链接。POI的所有内容都非常复杂，我建议您使用Maven来处理依赖项。
