Java使⽤itext5实现PDF表格⽂档导出最近拿到⼀个需求，需要导出PDF⽂档，市⾯上可以实现的⽅法有很多，经过测试和调研决定使⽤itext5来实现，话不多说，说⼲就⼲。

1.依赖导⼊<!-- https:///artifact/com.itextpdf/itextpdf --><dependency><groupId>com.itextpdf</groupId><artifactId>itextpdf</artifactId><version>5.5.13.1</version></dependency><!-- https:///artifact/com.itextpdf/itext-asian --><dependency><groupId>com.itextpdf</groupId><artifactId>itext-asian</artifactId><version>5.2.0</version></dependency>这⾥说明下：上⾯的依赖就是主要实现PDF⽣成的，下⾯的依赖是中⽂字体相关依赖；2.PDF表格导出实现1.导出PDF// 1.打开⽂档并设置基本属性Document document = new Document();// 2.设置请求头，encode⽂件名response.setContentType("application/pdf;charset=UTF-8");response.setHeader("Content-Disposition","attachment; filename=" + .URLEncoder.encode("" +recordDto.getTitle() + ".pdf", "UTF-8"));// 3.通过流将pdf实例写出到浏览器PdfWriter writer = PdfWriter.getInstance(document, response.getOutputStream());⾄此导出PDF已经实现了，只是这个PDF中什么内容都没有，明⽩这⼀点，接下来做的就是给这个⽂档“加料”咯(这⾥的response就是HttpServletResponse)。

基于iTextSharp的PDF操作（PDF打印，PDF下载）准备1. iTextSharp的简介iTextSharp是一个移植于java平台的iText项目，被封装成c#的组件来用于C#生成PDF 文档，目前，也有不少操作PDF的类库，（国产的有福盺的，免费试用，用于商业用途收费）但是功能普遍没有iText强大，而且使用没有iText广泛。

还有他就是开源的。

目前比较新的是5.5版本的。

2. 使用工具硬件：PC机：一台软件：Windows操作系统Isual studio 2013 (可以是任意版本).Net frameWork 4.5 (可以是任意版本)iTextSharp 5.5 可以到官网下载（iTextSharp）/projects/itextsharp/下载后，解压得到iTextSharp.dll文件基本知识1. 主要对象1）.Document 对象：Document 对象主要用于操作页面的大小，就是页面的尺寸。

页面的尺寸一般有以下几种：A0-A10, LEGAL, LETTER, HALFLETTER, _11x17, LEDGER, NOTE, B0-B5, ARCH_A-ARCH_E, FLSA 和 FLSE，例如，需要创建一个A4纸张大小的PDF文档：Document document = new Document(PageSize.A4);这个文档漠然是纵向的，如果满足不了你横向文档的需要，可以加上rotate属性。

有的时候，我们需要生成特定颜色的，特定大小的PDF文档，可以使用下面的方法Rectangle pageSize = new Rectangle(120, 520); //120*520规格pageSize.BackgroundColor = new Color(0xFF, 0xFF, 0xDE); //背景色Document document = new Document(pageSize); //新建Documen对象页边距：Document document = new Document(PageSize.A5, 36, 72, 108, 180);//默认单位为磅。

三、要实现打印的Jsp文件编写，Jsp文件中打印按钮或者打印连接应该提交给一个javascript，具体代码如：<a href="javascript: print(${exammanage.oid })"><fontcolor="blue">打印</font></a>javascript代码如下function print(oid){if(!confirm("确定要打印该资格证吗？"))return ;window.showModalDialog('${ctx}/exam/exammanage/examprint_cert.jsp?oid='+oid,'','dialogWidth:50px;dialogHeight:150px;dialogTop:1000px;dialogLef t:1000px');document.forms[0].flg.value = "０";document.forms[0].action="${ctx}/ExamPermitPrint.html";document.forms[0].submit();}代码解释：1、window.showModalDialog('${ctx}/exam/exammanage/examprint_cert.jsp?oid='+oid,'','dialogWidth:50px;dialogHeight:150px;dialogTop:1000px;dialogLef t:1000px');此段的功能是显示打印提示窗口，我的文件是WebRoot路径下/exam/exammanage/路径下的examprint_cert.jsp文件，而且需要传一个你所要打印的记录的唯一字段（数据库中唯一代表一条记录的字段），我这里用OID。

1概述面对管理系统中复杂的数据,报表作为数据管理工具,帮助用户快速掌握原始数据中的基本关系,直观的让用户感受到数据的变化,使用户对事务最新的形势状况能够在第一时间掌握并做出正确的决策判断。

传统处理报表的方式是使用Excel,Word等编辑软件进行人为的数据统计。

这种人工统计数据、填写报表的方式不仅效率低下,还容易出错。

为了提高单位工作人员协同办公效率,减少传统报表在生成和使用时所带来的不足之处。

越来越多的单位选择使用信息化办公,即只向系统数据库录入一次数据,再根据数据库中已有数据集进行数据处理、报表打印。

2浏览器直接生成报表利用浏览器自带的打印功能实现报表打印,无疑是所有实现打印报表功能方式中最直接的。

客户端不用下载其他额外的插件,不需要多余的环境配置,便可以很方便的通过浏览器直接实现报表功能打印。

利用浏览器直接生成报表主要有以下4个步骤:步骤一:建立数据库连接。

DBUil db=new DBUtil();步骤二:用JavaBean定义相应的数据操作语言,获取数据集。

public List getAlInfomationO{List infomations=null://初始化报表数据集合infomationsSuing sql="select*from infomations"; //生成数据库查询语句infomations=db.getList(sql,null);//将数据集放入//集合infomations中retum infomations;}步骤三:根据制作报表页面需要的样式。

<IDOCTYPE htm><html>//报表页面设计<head><meta http equiv="Content-Iype"><title></tite><head>//设置网页标题<body><body>//设计网页内容,例如:表格,div流//对象</html>步骤四:通过Jsp获取数据库中报表参数集并向前端传递。

java利⽤itext导出pdf项⽬中有⼀功能是导出历史记录，可以导出pdf和excel，这⾥先说导出pdf。

在⽹上查可以⽤那些⽅式导出pdf，⽤itext⽐较多⼴泛。

导出pdf可以使⽤两种⽅式，⼀是可以根据已有的pdf模板，进⾏⽣成⽂档。

⼆是直接⽤代码⽣成pdf⼀、使⽤模板⽣成pdf1、添加依赖<dependency><groupId>com.itextpdf</groupId><artifactId>itextpdf</artifactId><version>5.5.10</version></dependency><dependency><groupId>com.itextpdf</groupId><artifactId>itext-asian</artifactId><version>5.2.0</version></dependency>2、创建word，创建需要的样式，例如，保存为pdf格式，3、使⽤Adobe Acrobat 打开，打开内容编辑，选择编辑域，编辑域的名称与代码的数据属性名对应。

4、java代码import java.io.ByteArrayOutputStream;import java.io.FileOutputStream;import java.util.Iterator;import com.itextpdf.text.Document;import com.itextpdf.text.pdf.AcroFields;import com.itextpdf.text.pdf.PdfCopy;import com.itextpdf.text.pdf.PdfImportedPage;import com.itextpdf.text.pdf.PdfReader;import com.itextpdf.text.pdf.PdfStamper;/*** @Title: CreatePdf.java* @Description: TODO* @author zhangjunhong* @date 2018年10⽉22⽇*/public class CreatePdf {public static void fillTemplate() throws Exception {//读取的模板String templatePath = "D:/mypdf1.pdf";//⽣成的pdf存储的路径String targetPath = "D:/test1.pdf";PdfReader reader;FileOutputStream outputStream;ByteArrayOutputStream bos;PdfStamper stamper;reader = new PdfReader(templatePath);outputStream = new FileOutputStream(targetPath);bos = new ByteArrayOutputStream();stamper = new PdfStamper(reader, bos);//取得模板表单对应的域AcroFields from = stamper.getAcroFields();String[] strings = { "12222", "zahang", "男", "1992-09-12" };int i = 0;Iterator<String> iterator = from.getFields().keySet().iterator();while (iterator.hasNext()) {String name = iterator.next().toString();System.err.println(name);from.setField(name, strings[i++]);}stamper.setFormFlattening(true);stamper.close();Document document = new Document();PdfCopy copy = new PdfCopy(document, outputStream);document.open();PdfImportedPage importedPage = copy.getImportedPage(new PdfReader(bos.toByteArray()), 1);copy.addPage(importedPage);document.close();}public static void main(String[] args) throws Exception{fillTemplate();}}5、结果⼆、根据数据⽣成pdf并导出,这个好像挺简单的，直接代码⼀波，看注释，也可以⽣成表格之类的@RequestMapping("/export/pdf")public void exPdf(HttpServletResponse response){OutputStream os=null;try {// 指定解析器System.setProperty("javax.xml.parsers.DocumentBuilderFactory",".apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl");String filename = "⼤⾯积延误历史记录详情.pdf";response.setContentType("application/pdf");response.setHeader("Content-Disposition","attachment;fileName=" + URLEncoder.encode(filename, "UTF-8"));os = new BufferedOutputStream(response.getOutputStream());//⽣成pdfDocument document=new Document();PdfWriter writer=PdfWriter.getInstance(document, os);// 页⾯⼤⼩Rectangle rectangle = new Rectangle(PageSize.A4);// 页⾯背景颜⾊rectangle.setBackgroundColor(BaseColor.WHITE);document.setPageSize(rectangle);// 页边距左，右，上，下document.setMargins(20, 20, 20, 20);document.open();//中⽂字体 ----不然中⽂会乱码BaseFont bf = BaseFont.createFont("STSong-Light", "UniGB-UCS2-H",BaseFont.NOT_EMBEDDED);//设置字体Font font = new Font(bf, 14, Font.BOLD, BaseColor.BLACK);Paragraph p=new Paragraph("设置了字体样式的标题哈哈哈哈哈今天⽐较闲嘤嘤嘤", font);document.add(p);document.close();} catch (Exception e) {e.printStackTrace();} finally {try {os.close();} catch (IOException e) {e.printStackTrace();}}还有很多对pdf的操作，如添加page，表格等，可查看itext的官⽅⽂档，最后是不是贴上我花了⼏天写的pdf导出，这个技术是简单了，尼玛项⽬业务逻辑贼复杂。

c#itextsharp根据模板导出pdf报表⼀、前⾔ PDF⽂件在⽬前来说是⽐较流⾏的电⼦⽂档格式，在.Net framework 中⾝并不包含可以和pdf打交道的⽅法，也没有很好操作PDF的类库，所以我们需要对pdf进⾏编辑，加密，模板打印等操作不得不去找可⽤的第三⽅组件，这⾥就可以选择使⽤ITextSharp来实现，这个程序是JAVA⼯具IText的.Net版本。

准备： 1、 2、简单的操作直接查看帮助⽂件，此处先省略后续考虑补充⼆、itextsharp 使⽤　2.1 pdf模板 本次讲的是根据pdf模板导出数据，⾸先创建模板，我这⾥使⽤的⼯具是Adobe Acrobat 视图——⼯具——准备表单，可以在需要赋值的地⽅放上⼀个⽂本框，把名字改成要⽤的名字。

这是编辑好后的效果　2.2 新建项⽬添加引⽤新建了⼀个导出数据测试窗体 load事件以及测试数据，///<summary>///模拟数据///</summary>DataTable dt;private void frmDemo1_Load(object sender, EventArgs e){#region模拟数据dt = new DataTable();dt.Columns.Add("number", typeof(string));dt.Columns.Add("name", typeof(string));dt.Columns.Add("yw", typeof(string));dt.Columns.Add("sx", typeof(string));dt.Columns.Add("yy", typeof(string));dt.Columns.Add("pd", typeof(string));dt.Columns.Add("pe", typeof(string));dt.Columns.Add("remark", typeof(string));DataRow dr = dt.NewRow();dr["number"] = "1";dr["name"] = "⼩明";dr["yw"] = "95";dr["sx"] = "90";dr["yy"] = "75";dr["pd"] = "80";dr["pe"] = "90";dt.Rows.Add(dr);dr = dt.NewRow();dr["number"] = "2";dr["name"] = "⼩红";dr["yw"] = "100";dr["sx"] = "90";dr["yy"] = "85";dr["pd"] = "100";dr["pe"] = "90";dt.Rows.Add(dr);dr = dt.NewRow();dr["number"] = "3";dr["name"] = "⼩芳";dr["yw"] = "95";dr["sx"] = "95";dr["yy"] = "90";dr["pd"] = "90";dr["pe"] = "90";dt.Rows.Add(dr);dataGridView1.DataSource = dt;#endregion}View Code封装了⼀个导出Pdf帮助类using iTextSharp.text.pdf;using System;using System.Collections.Generic;using System.IO;using System.Linq;using System.Text;namespace itextsharpDemo{///<summary>/// PDF导出类///</summary>public class PdfLeadingHelper{///<summary>///根据路径获取模板///</summary>///<param name="pdfTemplate"></param>///<returns></returns>public static Dictionary<string, string> ReadForm(string pdfTemplate){Dictionary<string, string> dic = new Dictionary<string, string>();PdfReader pdfReader = null;try{pdfReader = new PdfReader(pdfTemplate);AcroFields pdfFormFields = pdfReader.AcroFields;foreach (var de in pdfFormFields.Fields){dic.Add(de.Key, "");}}catch (Exception ex){dic = null;//记录⽇志注释// LogHelper.Logger(LogLevel.Error, "pdf导出类发⽣异常：根据路径获取模板时异常" + ex.ToString(), ex);}finally{if (pdfReader != null){pdfReader.Close();}}return dic;}//////向pdf模版填充内容，并⽣成新的⽂件//////模版路径///⽣成⽂件保存路径///标签字典(即模版中需要填充的控件列表)public static bool FillForm(string pdfTemplate, string newFile, Dictionary<string, string> dic){bool rsBool = true;PdfReader pdfReader = null;PdfStamper pdfStamper = null;try{pdfReader = new PdfReader(pdfTemplate);pdfStamper = new PdfStamper(pdfReader, new FileStream(newFile, FileMode.Create));AcroFields pdfFormFields = pdfStamper.AcroFields;//设置⽀持中⽂字体BaseFont baseFont = BaseFont.CreateFont("C:\\WINDOWS\\FONTS\\STSONG.TTF", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED); pdfFormFields.AddSubstitutionFont(baseFont);foreach (var de in dic){pdfFormFields.SetField(de.Key, de.Value + "");}pdfStamper.FormFlattening = true;}catch (Exception ex){//记录⽇志注释// LogHelper.Logger(LogLevel.Error, "pdf导出类发⽣异常：向pdf模版填充内容，并⽣成新的⽂件时异常"+ex.ToString(), ex); rsBool = false;}finally{if (pdfStamper != null){pdfStamper.Close();}if (pdfReader != null){pdfReader.Close();}}return rsBool;}}}导出按钮事件private void button1_Click(object sender, EventArgs e){//dic 获取学⽣成绩表 Pdf导出模板string templetPath = System.Environment.CurrentDirectory + @"\学⽣成绩表.pdf";Dictionary<string, string> dic = PdfLeadingHelper.ReadForm(templetPath);#region赋值 dicdic["className"] = textBox1.Text;for (int i = 1; i <= dt.Rows.Count; i++){if (dic.ContainsKey("number_" + i)){dic["number_" + i] = dt.Rows[i-1]["number"] +"";dic["name_" + i] = dt.Rows[i-1]["name"] + "";dic["yw_" + i] = dt.Rows[i-1]["yw"] + "";dic["sx_" + i] = dt.Rows[i-1]["sx"] + "";dic["yy_" + i] = dt.Rows[i-1]["yy"] + "";dic["pd_" + i] = dt.Rows[i-1]["pd"] + "";dic["pe_" + i] = dt.Rows[i-1]["pe"] + "";dic["remark_" + i] = dt.Rows[i-1]["remark"] + "";}}#endregion//保存SaveFileDialog dlg = new SaveFileDialog();dlg.FileName = "成绩单";dlg.DefaultExt = ".pdf";dlg.Filter = "Text documents (.pdf)|*.pdf";if (dlg.ShowDialog() == DialogResult.OK){bool rsBool = PdfLeadingHelper.FillForm(templetPath, dlg.FileName, dic);if (rsBool){MessageBox.Show("导出成功！！");}}}先获取pdf模板变量，Dictionary<string, string> dic 键值对类型赋值对应dic保存成新pdf这样⼀个⼩案例就完成了。

如何利用iText在java程序中生成PDF报表以下是上述教程中一个最简单的例子，这个例子刻画了通过iText生成PDF 文件的一般程序框架。

读者只需要在document.open();和document.close();两条语句中间加入自己希望放在PDF文件中的内容即可。

该例子只在PDF文件中加了“Hello World“一行文字。

Document document = new Document();try{PdfWriter.getInstance(document, new FileOutputStream("Chap0101.pdf"));document.open();document.add(new Paragraph("Hello World"));}catch(DocumentException de){System.err.println(de.getMessage());}catch(IOException ioe){System.err.println(ioe.getMessage());}document.close();由以上的例子可见，程序的框架十分清楚明了。

然而在PDF中指定文字、图画、表格的位置是一件非常麻烦的事情。

除了不断地在程序中修改位置、然后运行程序、生成PDF文件、观察元素在PDF中的位置是否合理这样的过程以外，似乎还没有其它更好的方法。

如何通过JSP生成PDF报表1）直接在服务器上生成PDF文件。

＜%@ page import ="com.lowagie.text.*,com.lowagie.text.pdf.*,java.io.*"%＞＜%String filename = "PDF"+(new Random()).nextInt()+".pdf" ; Document document = new Document(PageSize.A4); ServletOutputStream out1 = response.getOutputStream();try{PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(filename) );document.open();document.add(new Paragraph("Hello World"));document.close();}catch(Exception e){}%＞上面的程序在服务器上生成了一个静态的PDF文件。

JavaiText+FreeMarker⽣成PDF（HTML转PDF）1.背景在某些业务场景中，需要提供相关的电⼦凭证，⽐如⽹银/⽀付宝中转账的电⼦回单，签约的电⼦合同等。

⽅便⽤户查看，下载，打印。

⽬前常⽤的解决⽅案是，把相关数据信息，⽣成对应的pdf⽂件返回给⽤户。

本⽂源码：2.iTextiText是著名的开放源码的站点sourceforge⼀个项⽬，是⽤于⽣成PDF⽂档的⼀个java类库。

通过iText不仅可以⽣成PDF或rtf的⽂档，⽽且可以将XML、Html⽂件转化为PDF⽂件。

iText 官⽹：iText 开发⽂档：iText⽬前有两套版本iText5和iText7。

iText5应该是⽹上⽤的⽐较多的⼀个版本。

iText5因为是很多开发者参与贡献代码，因此在⼀些规范和设计上存在不合理的地⽅。

iText7是后来官⽅针对iText5的重构，两个版本差别还是挺⼤的。

不过在实际使⽤中，⼀般⽤到的都⽐较简单，所以不⽤特别拘泥于使⽤哪个版本。

⽐如我们在中搜索iText，出来的都是iText5的依赖。

itextpdfJAVA输出PDF⽂档使⽤JAVA⽣成PDF的时候，还是有些注意事项需要处理的。

第⼀、中⽂问题，默认的itext是不⽀持中⽂的，想要⽀持，需要做些处理。

1、直接引⽤操作系统的中⽂字体库⽀持，由于此⽅案限制性强，⼜绑定了操作系统，所以此处不做实现，有兴趣可在⽹上搜索看看。

2、引⽤itext-asian.jar包的字体⽀持，代码稍后上。

itext pdf引⼊中⽂常见异常： com.itextpdf.text.DocumentException: Font 'STSongStd-Light' with 'UniGB-UCS2-H' is not recognized. 解决⽅案：a、引⼊操作系统字体；2、将字体维护进jar包中，如果没有，直接找到字体放⼊对应jar包中，如果是路径错误，则更改包路径；3、通过itext-asian.jar来加载中⽂包。

第⼆、表格中的设置，特别是上中下，左中右，不同的对象有不同的枚举实现，刚⼊⼿很容易混淆。

其外是前景⾊，背景⾊，表格颜⾊等等。

第三、输出图⽚，很容易报错。

itext pdf常见输出图⽚异常： An error exists on this page. Acrobat may not display the page correctly. Please contact the person who created the PDF document to correct the problem. 原因：PdfContentByte在addImage的时候需要在beginText()和endText()范围以外调⽤，否则⽣成的PDF就会报上述错误。
