PDFBox EOFException：设置文本字段值时为空
PDFBox EOFException: null when setting textfield value
我正在尝试填写一张用 adobe acrobat 创建的 pdf 表单，该表单包含一个名为 'txt_name' 的文本字段。填写表格我使用的是 Apache PDFBox。
填写pdf表格的代码
try {
PDDocument pDDocument =
Loader.loadPDF(ResourceUtils.getFile("classpath:pdf/test.pdf"));
PDAcroForm pDAcroForm = pDDocument.getDocumentCatalog().getAcroForm();
pDAcroForm.getField("txt_name").setValue("test");
pDDocument.save("./src/main/resources/pdf/generated/test.pdf");
pDDocument.close();
} catch (IOException e) {
e.printStackTrace();
}
如您所见，我正在加载名为 'test.pdf' 的 pdf 文件。在此之后，我想用名称 'txt_name' 填写字段并将值设置为 'test'，但是当我尝试填写该字段时，我得到一个 EOFException.我也收到错误 'Could not load font file: C:\WINDOWS\FONTS\mstmc.ttf'。我的计算机上没有此文件，但当我尝试在网上查找有关此文件的任何信息时，我没有得到任何好的结果。
PDFBox 版本：
<dependency>
<groupId>org.apache.pdfbox</groupId>
<artifactId>pdfbox</artifactId>
<version>3.0.0-RC1</version>
</dependency>
我也尝试了不同的版本，但这行不通。

删除 mstmc.ttf 文件对我有用，该文件不是字体。 PDFbox 正在尝试读取此文件，但由于它不是字体，因此无法读取文件，这就是导致错误的原因。
感谢@mkl 和@Tilman hausherr 帮助了我。
