如何解决PDFBOX acroForm 已填充，但在 Acrobat 阅读器中打开时，值消失
我有 PDF 表格，我想用 PDFBox 填写它。它有效，表单已填写，我用其他阅读器或浏览器打开，我可以看到值，但是当我尝试在 Adobe Reader 中打开时，值消失了，我尝试了各种可能的方法来找出原因但值不可见。>
我有模板表单，我使用它并填写数据、重命名字段并将其合并到其他文档中，然后重做该过程，直到填写完所有表单。

这是我填充表单的代码。

数据类定义
data class diversionData(
val terminalirsCode: String,val fuelType: String,val supplierTaxPayerNumber: String,val shipperTaxPayerNumber: String,val quantity: Double,val originalDestination: String,val revisedDestination: String,val importNumber: String?,val date: LocalDate,val billOfLading: String,)
测试填写表格
@Test
public void fillFormUsingNewKotlinClass() throws IOException {
List<diversionData> diversionData = new ArrayList<>();
for (int i = 0; i < 20; i++) {
diversionData d = new diversionData(
"terminal_Code" + i,"Regular" + i,"supplier tax" + i,"shipper tax" + i,1000 + i,"TX","LA","0000" + i,LocalDate.Now().plusDays(i),"123456" + i
);
diversionData.add(d);
}
//E:/repo/gasjobber-docker/gasjobber-api/src/main/resources/
String path = "templates/taxFormsPDF/LA/5402(7_06)F.pdf";
diversionDataFormFiller filler = new diversionDataFormFiller();
Map<String,String> param = new HashMap<>();
param.put("Product Type","065");
param.put("Type of Schedule","22");
param.put("LA Revenue Account Number","3264660001");
param.put("Company Name","Test CO.");
param.put("Filling Period","2020-12");
PDDocument document = filler.fillForm(path,diversionData,param);
document.save(new File("C:\\Users\\Documents\\Downloads\\testpdf.pdf"));
document.close();
}
解决方法
页面 /AA/O 条目（“打开页面时应执行的操作”）具有以下内容：
if (!bReset)
{
this.resetForm();
bReset = true;
}
所以表单被重置了。
即使手动填写表单并保存、关闭并重新打开，也会发生这种情况。也许这是“formupack”的演示版本，它是故意这样做的。
您可以通过像这样删除页面 /AA 条目来防止这种情况
document.getPage(0).setActions(null);
或者只是删除 /O 条目
document.getPage(0).getActions().setO(null);
