Cant get a field of PDF with PDFBox

Question

我有一个带有单个字段“pls”的 pdf，当我调用 AcroForm getFields 的方法时，输出是这样的：“COSString{pls}”，但是当我调用方法 getField("pls") 时，它返回 null 并且我不能在场上做任何事情。

I had a project where I was looking for a field through his name CustomerSignature . Maybe this example can help you.

PDField myField;
for(PDField f : ((List<PDField>) pdfAccroForm.getFields())) {
    if(f.getPartialName()!= null && f.getPartialName().startsWith("CustomerSignature")) {
        myField= f;
    }
}
