我正在尝试在java中集成开放式办公室。我正在做的是创建一个文档，并希望以 pdf 格式获取该文档作为 jsp 响应。但我无法做到这一点。我能够创建一个空白的开放式办公文档并在其中填写所需的文本。然后我希望每当这个 jsp 运行时我们都会得到该文档作为 pdf 格式的响应。

转换代码是

if(!dir.exists())
{

如果你能帮助我，因为我是这个主题的新手。
最佳答案
哇!!! jsp 中的 Scriptlet...多么古老的学校!!
通常，您会在 Servlet 中执行此操作，而不是在 jsp 中执行此操作。 Jsp 通常用于响应 html，在本例中您希望将二进制写入响应输出流。
您可以在 jsp 的 scriptlet 中执行此操作
<%
response.getOutputStream().write(...);
%>
但我建议您改用Servlet。
或者更好的是，停止使用 15 年前的技术，选择一个 Web 框架并停止使用 jsp、scriptlet 和 servlet
关于Java、OpenOffice、创建获取文档作为 jsp 响应作为 pdf，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/45836099/
