Convierta un documento de Word a HTML usando Java
1. Introducción
Recientemente, debido a las necesidades del proyecto, necesito analizar y dividir documentos de Word. Siento que analizar Word directamente es un poco problemático, así que pensé que sería más conveniente convertir Word a un documento html primero y luego usar jsoup para analizar. el archivo html. Para el uso de jsoup, puede consultar la API correspondiente. La operación es simple, similar a javascript.
El método para convertir un documento de Word a HTML es el siguiente:
Generalmente, los sufijos de los archivos de Word son doc y docx. Docx es la extensión para documentos de Office Word 2007 y versiones posteriores; doc es la extensión para documentos guardados en Office Word 2003. Se requieren diferentes métodos para convertir Word a HTML en estos dos formatos.
2. Agregar dependencias
