我创建了一个表单，用户填写字段（名称，名字，编号，日期1，日期2，并在3个命题中选择：男人，女人，孩子）。 我希望我可以存储用户答案（将它们放入数据库中）并将它们合并到pdf文件中。
但我不能为我的pdf做任何功能，该怎么做？你有什么建议或例子吗？ 我应该生成一个pdf模板，之前用户会回答吗？我尝试用'itextpdf'做一些事但没有成功 另一种策略？
帮帮我！
这是我的代码：
数据文件
public class Data {
private String name;
private String surname;
private Integer numb;
private String date1;
private String date2;
public Patient(String name, String surname, Integer numb, String date1, String date2) {
super();
this.name = name;
this.surname = surname;
this.numb = numb;
this.date1 = date1;
this.date2 = date2;
}
public String getName() {
return name;
}
public String getSurname() {
return surname;
}
public Integer getNumb() {
return numb;
}
public String getDate1() {
return date1;
}
public String getDate2() {
return date2;
}
}

您可以使用 itext 工具生成pdf文件。你应该对它充满信心。 关于在java编程中使用itext pdf工具有很多例子。
你已经有了用pdf显示的数据，只需创建一个名为GeneratePdf的类并使用它。您只需将数据提供给itext段落，表格，单元格，无论您需要什么。
here中的示例。
