java使用itext生成pdf

        这里使用自己实践过的java来实现生成pdf，参考了很多资料，文章后面有列出来：

开始之前需要引入包：

 
        
            com.itextpdf
            itextpdf
            5.5.13
        


        
            com.itextpdf
            itext-asian
            5.2.0
        

        
        
            com.itextpdf.tool
            xmlworker
            5.5.13
        

        
        
            org.bouncycastle
            bcprov-jdk15on
            1.60
        

 

 

demo：

package com.jack.studytest.pdf;

import com.itextpdf.text.*;
import com.itextpdf.text.pdf.*;
import com.itextpdf.text.pdf.draw.DottedLineSeparator;
import com.itextpdf.text.pdf.draw.LineSeparator;
import com.itextpdf.text.pdf.draw.VerticalPositionMark;

import java.io.FileOutputStream;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.zip.ZipEntry;
import java.util.zip.ZipOutputStream;
