如何使用javafx從文本字段存儲和生成pdf
[英]How to store and generate a pdf from text fields using javafx
問題描述
我創建了一個表單，用戶在其中填寫字段（姓名，名字，數字，date1，date2，然后在3個命題之間進行選擇：男人，女人，孩子）。 我希望我可以存儲用戶答案（將它們放入數據庫中）並將其合並到pdf文件中。
但是我無法為pdf執行任何功能，該怎么做？ 您有什么建議或例子嗎？ 我是否應該生成一個pdf模板，然后才能由用戶回答？ 我試圖用'itextpdf'做點什么，但沒有成功，是另一種策略嗎？
幫我！
這是我的代碼：
資料檔案
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;
}
}
dataManager文件
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.ArrayList;
import main;
import models.data;
public class DataManager {
private Main main;
public DataManager(Main main) {
super();
this.main = main;
}
public void addData(data p) {
String query = "INSERT INTO Data(name, surname, numb, date1, date2) VALUES ("
+ "\"" + p.getName() + "\", "
+ "\"" + p.getSurname() + "\", "
+ "\"" + p.getNumb() + "\", "
+ "\"" + p.getDate1() + "\", "
+ "\"" + p.getDate2() + "\");";
try {
this.main.getDatabase().connect();
this.main.getDatabase().updateValue(query);
}
catch (Exception e) {
e.printStackTrace();
}
finally {
this.main.getDatabase().disconnect();
}
}
public ArrayList<Data> getData() {
ArrayList<Data> data = new ArrayList<Data>();
String query = "SELECT name, surname, numb, Date1, Date2 FROM Data ORDER BY name";
try {
this.main.getDatabase().connect();
ResultSet rslt = this.main.getDatabase().getResultOf(query.toString());
while (rslt.next()) {
data.add(new Data(rslt.getString("name"), rslt.getString("surname"), rslt.getInt("numb"),rslt.getString("Date1"),rslt.getString("Date2")));
}
rslt.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
finally {
this.main.getDatabase().disconnect();
}
return data;
}

您可以使用itext工具生成pdf。 您應該對此充滿信心。 有很多關於在Java編程中使用itext pdf工具的示例。
您已經有要以pdf格式顯示的數據，只需創建一個名為GeneratePdf的類並使用它即可。 您只需要將數據提供給itext段落，表，單元格即可。
這里的例子。
