使用docx4j从.dotx模板生成.docx文档（在XPages应用程序中）

Question

有人能告诉我如何使用docx4j将.dotx文件转换为.docx文件吗？

我当前使用的代码是：

Answer 1

一般而言，模板（.dotx）和文档（.docx）之间有几个区别。这意味着您需要做一些事情--无论您是将文档保存为模板，还是试图从模板创建文档，这都不是仅仅更改文件扩展名那么简单。

希望本大纲将有助于：

1. 首先执行您已经执行的操作：您的新文档应该是模板的文件副本
2. 根据需要更改新的WordProcessingMLPackage的文档类型（请参阅ContentTypes类中的WordProcessingML_Template
3. 创建附加模板并将其附加到文档：有关此方面的详细信息，请参阅Github上的示例代码(TemplateAttach.java示例）。
