## 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){

                                ArrayList<HashMap<String,String>> experienceListBean = MsgUtil.experienceList.get(i);
    	    					List<HashMap<String,String>> educationList = new ArrayList<HashMap<String,String>>();//教育经历

    	    							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);

            	}
            }
    
    
    
            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/");
        }
    
    }

## 三、运行结果 ##

上方代码执行后，可以生成一份个人简历pdf，如下：

**如果需要增加内容、调整内容，自行修改代码即可。**
