文章标签 java设置pdf文件不分页 java pdf 开发语言 System 文章分类 Java 后端开发

一、概述

以下代码可以在指定文件夹内创建一个简历pdf。

以下代码生成pdf，主要是设置cell所占的行、列、内容。

二、代码

1.需要的jar包

itext-asian-5.2.0.jar
itextpdf-5.5.5.jar

2.个人信息类MsgUtil.java

这个类里面放了个人信息；也可以放多个人的、生成多个pdf；代码如下：

import java.util.ArrayList;
import java.util.HashMap;

/**
 * 个人信息类
 */

public class MsgUtil {


    public static final ArrayList<HashMap<String,String>> baseMsgList = new ArrayList<>();
    public static final ArrayList<ArrayList<HashMap<String,String>>> experienceList = new ArrayList<>();



    static{
        //装入第一个人的信息
        addMsg1();

    }

    /**
     * 装入1个人的信息，还有就复制下这个方法，再加，然后static里调用下装进去
     */
    private static void addMsg1(){
        //第一个人的信息

        //这个只有1行数据，是1个map
        HashMap<String, String> baseMsgListMy = new HashMap<>();
        baseMsgList.add(baseMsgListMy);



        baseMsgListMy.put("FullName","小明");
        baseMsgListMy.put("Gender","男");
        baseMsgListMy.put("Birthdate","2002-01-10");
        baseMsgListMy.put("Card","1001112002011VWXYZ");

        baseMsgListMy.put("HomeAddress","北京");
        baseMsgListMy.put("detailAdress","海淀区");
        baseMsgListMy.put("Tel","142xxxxzzzz");
        baseMsgListMy.put("E_mail","test@qq.com");
        baseMsgListMy.put("Wechat","testqq");
        baseMsgListMy.put("Linkman","大明");
        baseMsgListMy.put("Relationship","朋友");
        baseMsgListMy.put("LinkmanTel","123ddddpppp");


        //工作经历list
        ArrayList<HashMap<String, String>> experienceListMy = new ArrayList<>();
        experienceList.add(experienceListMy);

        //工作经历，第一个map（第一行数据，还有就再加）
        HashMap<String, String> experienceMap1 = new HashMap<>();
        experienceListMy.add(experienceMap1);
        experienceMap1.put("Type","2");
        experienceMap1.put("TimeFrom","2022.01.01");
        experienceMap1.put("Time","2022.02.02");
        experienceMap1.put("School","公司");
        experienceMap1.put("Degree","员工");

        //工作经历，第二个map（第二行数据，还有就再加）
        HashMap<String, String> experienceMap2 = new HashMap<>();
        experienceListMy.add(experienceMap2);
        experienceMap2.put("Type","2");
        experienceMap2.put("TimeFrom","2022.01.01");
        experienceMap2.put("Time","2023.01.01");
        experienceMap2.put("School","国企");
        experienceMap2.put("Degree","员工");

        HashMap<String, String> experienceMap3 = new HashMap<>();
        experienceListMy.add(experienceMap3);
        experienceMap3.put("Type","1");
        experienceMap3.put("TimeFrom","2122.01.01");
        experienceMap3.put("Time","2123.01.01");
        experienceMap3.put("School","大学");
        experienceMap3.put("Degree","学士");

        HashMap<String, String> experienceMap4 = new HashMap<>();
        experienceListMy.add(experienceMap4);
        experienceMap4.put("Type","1");
        experienceMap4.put("TimeFrom","2122.01.01");
        experienceMap4.put("Time","2123.01.01");
        experienceMap4.put("School","高中");
        experienceMap4.put("Degree","毕业");


    }


}

3.生成pdf工具类CreatePdfUtil.java

这个类有生成pdf的方法，如果调整pdf格式就需要修改这个类，代码如下：

import com.itextpdf.text.*;
import com.itextpdf.text.pdf.BaseFont;
import com.itextpdf.text.pdf.PdfPCell;
import com.itextpdf.text.pdf.PdfPTable;
import com.itextpdf.text.pdf.PdfWriter;



import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;

import java.util.ArrayList;

import java.util.HashMap;
import java.util.List;

/**
 * 生成PDF简历工具类
 */
public class CreatePdfUtil {


	public static void createPdf(Integer total, String filePath){



		try{

            System.out.println("生成所有开始时间："+System.currentTimeMillis());

			if(total!=null && total>0){
				int count=0;
				
                ArrayList<HashMap<String,String>> baseMsgList = MsgUtil.baseMsgList;
                
				for(int i=0;i<total;i++){
	    		    
	    			if(baseMsgList!=null && baseMsgList.size()>0){
                        HashMap<String,String> baseMsgBean = baseMsgList.get(i);
	    				if(baseMsgBean!=null && baseMsgBean.get("Card") != null){

                            ArrayList<HashMap<String,String>> experienceListBean = MsgUtil.experienceList.get(i);
	    					List<HashMap<String,String>> educationList = new ArrayList<HashMap<String,String>>();//教育经历
	    					List<HashMap<String,String>> workList = new ArrayList<HashMap<String,String>>();//工作经历
	    					if( experienceListBean!= null && experienceListBean.size()>0){
	    						for(int j=0;j<experienceListBean.size();j++){
                                    HashMap<String,String> Bean = experienceListBean.get(j);
	    							if("1".equals(Bean.get("Type"))){//教育
	    								educationList.add(Bean);
	    							}else if("2".equals(Bean.get("Type"))){//工作
	    								workList.add(Bean);
	    							}
	    						}
	    					}

	    					try{
	    						Document document = new Document(PageSize.A4);
	    						PdfWriter.getInstance(document,new FileOutputStream(filePath+baseMsgBean.get("Card")+".pdf"));
	    						document.open();
	    						PdfPTable table = createTable(baseMsgBean,workList,educationList);
	    						document.add(table);
	    						document.close();
	    					}catch(Exception e){
                                System.out.println("生成简历异常！");
	    						e.printStackTrace();
	    						//生产简历异常后删除创建的文件
	    						String filepath = filePath+baseMsgBean.get("Card")+".pdf";
	    						File file = new File(filepath);
	    						if (file.exists()) {
	    							file.delete();
	    						}
	    					}
	    					count = count+1;
	    				}
	    			}
	    		}

                System.out.println("生成所有结束时间："+System.currentTimeMillis());


	    	}
		}catch(Exception e){
			System.out.println("生成简历失败！");
			System.out.println(e);
		}
    }

                table.addCell(cell);
        	}
        }



        return table;
	}
}

4.入口方法Main.java

这个类就是程序的入口，代码如下：

public class Main {

    public static void main(String[] args) throws Exception {

        //生成pdf的个数，生成pdf存放的文件夹
        CreatePdfUtil.createPdf(1,"f:/jl/");
    }

}
