Java用itextpdf導(dǎo)出PDF方法(通俗易懂)
更新時(shí)間：2023年07月19日 14:49:30 作者：就一個(gè)碼農(nóng)zZ
因?yàn)轫?xiàng)目需要導(dǎo)出PDF文件,所以去找了一下能夠生成PDF的java工具,這篇文章主要給大家介紹了關(guān)于Java用itextpdf導(dǎo)出PDF的相關(guān)資料,文中介紹的方法通俗易懂,需要的朋友可以參考下
前言
在java開發(fā)的過程中會(huì)遇到太多太多文檔pdf導(dǎo)出，excle導(dǎo)出等業(yè)務(wù)場(chǎng)景，時(shí)隔三個(gè)月或半年來一次每一次遇到這樣的業(yè)務(wù)場(chǎng)景對(duì)我都是非常痛苦的過程，本文旨在記錄工具類使用方法和技術(shù)分享。
一、itextpdf是什么？
itextpdf是一個(gè)開源的Java庫(kù)，用于創(chuàng)建和操作PDF文檔。使用itextpdf，您可以創(chuàng)建新的PDF文檔或修改現(xiàn)有文檔，添加文本和圖像，創(chuàng)建表單等等。該庫(kù)提供了廣泛的功能，并經(jīng)常用于企業(yè)級(jí)應(yīng)用程序中根據(jù)用戶輸入動(dòng)態(tài)生成復(fù)雜的PDF文檔。它具有各種許可證選項(xiàng)，具體取決于您的用例，范圍從AGPL到商業(yè)許可證。
itextpdf庫(kù)提供了大量的方法和功能，以下是一些常用的方法：
- 創(chuàng)建PDF文檔和頁(yè)面：使用PdfWriter和Document對(duì)象可以創(chuàng)建一個(gè)新的PDF文檔并添加頁(yè)面。
- 添加內(nèi)容到PDF文檔：使用Paragraph、Phrase和Chunk對(duì)象可以向PDF文檔中添加文本內(nèi)容。同時(shí)，也可以添加圖片、表格等其它類型的內(nèi)容。
- 創(chuàng)建表格：使用PdfPTable對(duì)象可以創(chuàng)建表格，并向其中添加行和單元格。
- 設(shè)置頁(yè)眉頁(yè)腳：使用HeaderFooter對(duì)象可以設(shè)置PDF文檔的頁(yè)眉和頁(yè)腳，以及頁(yè)碼等信息。
- 創(chuàng)建書簽：使用PdfOutline對(duì)象可以創(chuàng)建PDF文檔的書簽，方便用戶在瀏覽器中導(dǎo)航。
- 導(dǎo)出PDF文檔：使用PdfWriter對(duì)象可以將PDF文檔導(dǎo)出為文件或流。
二、快速開始
1.廢話不多說，效果先上一波
下列數(shù)據(jù)均為測(cè)試虛擬數(shù)據(jù)，不具有任何真實(shí)性
2.依賴引入
