iText 5 PdfAction.javaScript（）在添加PushButtonField后在Adobe Acrobat中不起作用

Question

• 这里我正在使用iText（v-5.5.13）和Java 8将按钮添加到PDF文件中]。
• 使用此按钮，我将操作设置为一个JavaScript警报的按钮
• 按钮已成功添加，但是当我单击PDF中的按钮时按钮的操作未调用，这表示JavaScript警报不起作用
。
• 如果我将removeXfa()添加到AcroFields，则此工作正常，但是PDF表单字段的[[验证
无法工作，这就是为什么我无法删除XFA的原因看起来像这样[[在Adobe Acrobat中不起作用，但是在
• Foxit Reader中，它可以正常工作
] >>实际上，我希望使用API​​调用而不是警报，但是这里不调用警报
• 这是我的Java代码

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;

import com.itextpdf.text.DocumentException;
import com.itextpdf.text.Rectangle;
import com.itextpdf.text.pdf.GrayColor;
import com.itextpdf.text.pdf.PdfAction;
import com.itextpdf.text.pdf.PdfAnnotation;
import com.itextpdf.text.pdf.PdfFormField;
import com.itextpdf.text.pdf.PdfReader;
import com.itextpdf.text.pdf.PdfStamper;
import com.itextpdf.text.pdf.PushbuttonField;

public class AddField {

    public static final String SRC = "E:/projects/PDF_Manipulation/SRC/abc.pdf";
    public static final String DEST = "E:/projects/PDF_Manipulation/DEST/abc-added-button.pdf";

    public static void main(String[] args) throws DocumentException, IOException {
        File file = new File(DEST);
        file.getParentFile().mkdirs();
        new AddField().manipulatePdf(SRC, DEST);
    }

    public void manipulatePdf(String src, String dest) throws DocumentException, IOException {

        PdfReader reader = new PdfReader(src);
        PdfReader.unethicalreading = true;
        reader.removeUsageRights();

        PdfStamper stamper = new PdfStamper(reader, new FileOutputStream(dest));

        /* If I add removeXfa() to AcroFields then this working but validation of PDF form field is not working thats why i can't remove XFA */
        /* final AcroFields formx = stamper.getAcroFields();
        formx.removeXfa();
        formx.setGenerateAppearances(true); */

        PushbuttonField button = new PushbuttonField(stamper.getWriter(), new Rectangle(36, 700, 72, 730), "SAVE");
        button.setText("SAVE");
        button.setBackgroundColor(new GrayColor(0.75f));
        button.setVisibility(PushbuttonField.VISIBLE_BUT_DOES_NOT_PRINT);

        PdfFormField submit = button.getField();
        Rectangle rect = new Rectangle(550, 5, 580, 20);
        submit.setWidget(rect, PdfAnnotation.HIGHLIGHT_INVERT);

        String exportPdfJavascript = "app.alert('Testing........')";
        submit.setAction(PdfAction.javaScript(exportPdfJavascript, stamper.getWriter()));

        stamper.addAnnotation(submit, 1);

        stamper.close();
    }
}

这是我的build.gradle文件

apply plugin: 'java-library'

repositories {
    jcenter()
}

dependencies {
    // https://mvnrepository.com/artifact/com.itextpdf/itext7-core
    compile group: 'com.itextpdf', name: 'itextpdf', version: '5.5.13'

这里我正在使用iText（v-5.5.13）和Java 8将按钮添加到PDF文件中。使用此按钮，我将操作设置为Button，它是一个JavaScript警报按钮...
