我正在尝试使用Java将一个名为source.fo的文件转换为result.pdf文件。
我希望达到与调用Apache Fop命令相同的结果：
fop -fo source.fo -pdf result.pdf
也许这不是问题的重点，但我已经成功使用Freemarker模板创建了这些.fo文件。在我在Google上找到的所有使用Java FOP库的示例中，它们使用XML和XSL-FO文件创建PDF，但这不适用于我的情况。
我的备选方案（我正在尝试避免）是调用系统命令。
非常感谢您的帮助。

1你读过FOP: Embedding吗？还有什么问题吗？（我只在命令行上调用它，但我无法想象他们不会合理地记录您的用例） - undefined
我猜不是，但这就是我所需要的，谢谢！ - undefined
