Java對(duì)Excel表格的上傳和下載處理方法

更新時(shí)間：2017年08月06日 10:37:45 作者：blue_wz

這篇文章主要介紹了Java對(duì)Excel表格的上傳和下載處理方法,需要的朋友可以參考下

Excel表格文件的上傳和下載，java中涉及到文件肯定會(huì)有io流的知識(shí)。

而excel文件就要涉及到poi技術(shù)，而excel的版本包括：2003-2007和2010兩個(gè)版本，即excel的后綴名為：xls和xlsx。

這里我是按照正規(guī)的項(xiàng)目流程做的案例，所以可能會(huì)比網(wǎng)上的一些Demo復(fù)雜一些。不過(guò)文件的上傳和下載基本都是一套固定的流程，只是每個(gè)人的實(shí)現(xiàn)方式不太相同。

數(shù)據(jù)庫(kù)我用的是MySql。

下面是我的項(xiàng)目目錄：

按照正常的項(xiàng)目做了分層處理，文件上傳的業(yè)務(wù)我放到了service處理，而文件下載業(yè)務(wù)還在controller層。

對(duì)前端請(qǐng)求處理，我分成了兩個(gè)方法都放在HandleExcelController里面，這個(gè)類繼承了BaseExcelController,基本的文件操作處理在BaseExcelController里面。

BaseExcelController繼承了BaseController，BaseController類是所有controller的父類，這里用到的不太多，這個(gè)類封裝了response返回值等的處理等一些方法。

項(xiàng)目中除了springMVC和mybatis的jar包之外還引入了：

上傳和下載excel文件：

1、創(chuàng)建需要上傳的excel文件，為了簡(jiǎn)化，我這里只寫(xiě)了四列，即四個(gè)字段

2、創(chuàng)建jsp頁(yè)面

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
 <head>
 <title>Excel文件處理</title> 
 <script type="text/javascript" src="<c:url value='/res/js/jquery.js'/>"></script>
 <script>
  $(function(){
   var $wrap = $(".wrap");
   var find = function(str){
    return $wrap.find(str);
   }
   var getJname = function(name){
    return find("input[name='"+name+"']");
   }
   getJname("Upload").click(function(){
     var form = new FormData(document.getElementById("tf"));
     $.ajax({
     url:"<c:url value='/File/UploadExcel'/>",
     type:"post",
     data:form,
     dataType:"json",
     processData:false,
     contentType:false,
     success:function(data){
      //window.clearInterval(timer);     
       if(data.success == "success"){
        alert("提交文件成功,已將數(shù)據(jù)存入數(shù)據(jù)庫(kù)");
       }
     },
     error:function(e){
      alert("錯(cuò)誤！");
      //window.clearInterval(timer);
     }
    });
    })
   getJname("Download").click(function(){
    $.post("<c:url value='/File/DownLoadExcel'/>",{"id":"3"},function(data){
     //alert("下載文件成功");
    },"json")
   })
  })
 </script>
 </head>
 <body>
  <div class="wrap">
   <form id="tf">
    <p>
     <input type="file" name="file" value="選擇文件"/>
    Excel文件上傳：<input type="button" name="Upload" value="upload"/>
   </p>
   <p>
    Excel文件下載：<input type="button" name="Download" value="updown"/>
   </p>    
   </form>
  </div>
 </body>
</html>

3、依次創(chuàng)建controller、service、domain、mapper層，注意它們的依賴關(guān)系

1）、controller層的處理，在HandleExcelController里面注入BaseExcelService。因?yàn)橹皇亲鰝€(gè)示范，所欲我這里將泛型固定為Students類

BaseExcelController代碼：

  return filename;
 }
}

HandleExcelController用來(lái)處理前端請(qǐng)求，代碼如下：

package cn.wangze.controller;
import java.io.File;
import java.util.List;
import javax.servlet.ServletOutputStream;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import org.apache.commons.io.FileUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.multipart.MultipartFile;
import cn.wangze.domain.Students;
import cn.wangze.service.BaseExcelService;
@Controller
@RequestMapping("/File")
public class HandleExcelController extends BaseExcelController{
 @Autowired
 private BaseExcelService baseExcelService;
 @RequestMapping("/UploadExcel")
 public void UploadExcel(MultipartFile file,HttpSession session,HttpServletResponse response) throws Exception{
  //如果上傳的文件不存在，拋出異常
  if(file == null){
   throw new Exception("文件不存在");
  }
  //獲取文件名
  String fileName = file.getOriginalFilename();
  //選擇上傳的文件存放到項(xiàng)目的路徑
  String path = session.getServletContext().getRealPath(separator+"res"+separator+"upload");
  if(!checkPathName(fileName,response)) return ;
  String msg = baseExcelService.loadExcel(getSheet(file, path, fileName));
  sendMsg(true,msg,response);  
 }
 @RequestMapping("/DownLoadExcel")
 public void UpdownExcel(Students student,HttpServletResponse res,HttpSession session,HttpServletResponse response)
  throws Exception{
  List<Students> stus = baseExcelService.queryList(student);
  if(stus.size()==0){
   res.sendRedirect("/index.jsp");
   return;
  }
  //下載的excel文件存放的本地路徑
  String path = session.getServletContext().getRealPath(separator+"res"+separator+"exportExcel"+separator);
  ServletOutputStream os = res.getOutputStream();
  Students t = baseExcelService.queryTotal(student);
  //標(biāo)題文字，數(shù)值中的第一個(gè)值+當(dāng)前日期為文件名稱，以后的每個(gè)元素為每列的標(biāo)題
  String[] title={"studets04","id","名字","年齡","性別"};//標(biāo)題文字
  //對(duì)應(yīng)實(shí)體類的屬性值
  String[] parameters ={"id","name","age","sex"};
  String[] endContent = {"","","",""};
  //調(diào)用父類的處理方法，生成excel文件
  String filename = getOutputName(stus,path,title,parameters,t,endContent);
  try { 
    res.reset();
   res.setCharacterEncoding("utf8");
   res.setContentType("application/vnd.ms-excel;charset=utf8");
   res.setHeader("Content-Disposition", "attachment;fileName="
      +new String(filename.getBytes("utf-8"),"iso-8859-1")); 
   os.write(FileUtils.readFileToByteArray(new File(path+separator+filename))); 
   sendResult(true,response);
   os.flush(); 
  } finally { 
   if (os != null) { 
    os.close(); 
   } 
  }
 }
}

2）、service層的處理，把StudentsMapper注入到BaseExcelService

BaseExcelService代碼：

package cn.wangze.service;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import javax.servlet.ServletOutputStream;
import javax.servlet.http.HttpSession;
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.ss.usermodel.Sheet;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import cn.wangze.domain.Students;
import cn.wangze.mapper.StudentsMapper;
@Service
public class BaseExcelService {
 @Autowired
 private StudentsMapper<Students> studentsMapper;
 //判斷字符串是否為空
 public boolean isEmpty(String str) {
  return str == null || str.length() == 0;
 }
 //獲取單個(gè)表格(字段)存放的信息
 private String getValue(Cell cell,String cellLable,Map<String,String> errMap){
  cell.setCellType(Cell.CELL_TYPE_STRING);
  String value = cell.getStringCellValue().trim();
  return value;
 }
 //通過(guò)這個(gè)方法將excel表的每行的數(shù)據(jù)放到info對(duì)象里面
 private String addInfo(Row row,Students info){
  Map<String,String> errMap = new HashMap<String,String>();
  String id = getValue(row.getCell(0),"ID",errMap);
  String username = getValue(row.getCell(1),"姓名",errMap);
  String age = getValue(row.getCell(2),"年齡",errMap);
  String sex = getValue(row.getCell(3),"性別",errMap);
  String errMsg = errMap.get("errMsg");
  if(!isEmpty(errMsg)){
   return errMsg;
  }
  info.setId(id);
  info.setName(username);
  info.setAge(age);
  info.setSex(sex);
  return null;
 }
 public String loadExcel(Sheet sheet) throws Exception{
  //新建一個(gè)List集合，用來(lái)存放所有行信息，即每行為單條實(shí)體信息
  List<Students> infos = new ArrayList<Students>();
  //獲取到數(shù)據(jù)行數(shù)，第一行是title，不需要存入數(shù)據(jù)庫(kù)，所以rowNum從1開(kāi)始
  for (int rowNum = 1; rowNum <= sheet.getLastRowNum(); rowNum++) {
   Students info = new Students();
   String errMsg2 = addInfo(sheet.getRow(rowNum),info);
   if(errMsg2 != null) return errMsg2;
   infos.add(info);
  } 
  if(infos.isEmpty()){
   return "沒(méi)有解析到學(xué)生數(shù)據(jù)，請(qǐng)查驗(yàn)EXCEL文件";
  }
  //通過(guò)studentsMapper的insertSheetData方法，將實(shí)體類存放的數(shù)據(jù)插入到數(shù)據(jù)庫(kù)
  int result = studentsMapper.insertSheetData(infos);
  //若插入成功會(huì)返回大于1的整數(shù)，返回success
  if(result >= 1){
   return "success";
  }
  return "error";
 }
 //查詢所有數(shù)據(jù)庫(kù)存放的學(xué)生信息
 public List<Students> queryList(Students students){
  return studentsMapper.queryList(students);
 }
 //獲取到的學(xué)生實(shí)體信息
 public Students queryTotal(Students students){
  return studentsMapper.queryTotal(students);
 }
 public void downExcel(HttpSession session,String separator){
 }
}

3）、實(shí)體層的處理，字段要對(duì)應(yīng)excel表的字段

package cn.wangze.domain;
public class Students {
 String id;
 String name;
 String age;
 String sex;
 public String getId() {
  return id;
 }
 public void setId(String id) {
  this.id = id;
 }
 public String getName() {
  return name;
 }
 public void setName(String name) {
  this.name = name;
 }
 public String getAge() {
  return age;
 }
 public void setAge(String age) {
  this.age = age;
 }
 public String getSex() {
  return sex;
 }
 public void setSex(String sex) {
  this.sex = sex;
 }
}

4）、dao層處理：StudentsMapper.java是一個(gè)接口，業(yè)務(wù)到數(shù)據(jù)庫(kù)需要執(zhí)行的方法在這里聲明，StudentsMapper.xml相當(dāng)于接口的實(shí)現(xiàn)類，用來(lái)連接java和數(shù)據(jù)庫(kù)的操作。

StudentsMapper.java代碼：

package cn.wangze.mapper;
import java.util.List;
public interface StudentsMapper<T> {
 public int insertSheetData(List<T> list);
 public List<T> queryList(T t);
 public T queryTotal(T t);
}

StudentsMapper.xml代碼：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="cn.wangze.mapper.StudentsMapper">
 <sql id="ColumnList">
  id,name,age,sex
 </sql>
 <sql id="ColumnList_t" >
  t.id,t.name,t.age,t.sex
 </sql>
 <sql id="ValueList">
  #{id},#{name},#{age},#{sex}
 </sql>
 <sql id="WhereClause">
  where 1=1 
  <if test="id!=null and id!=''">and id=#{id}</if>
  <if test="name!=null and name!=''">and name=#{name}</if>
  <if test="age!=null and age!=''">and age=#{age}</if>
  <if test="sex!=null and sex!=''">and sex=#{sex}</if>
 </sql>
 <sql id="WhereClause_pager" >
  where 1=1 
  <if test="t.id!=null and t.id!=''">and id=#{t.id}</if>
  <if test="t.name!=null and t.name!=''">and name=#{t.name}</if>
  <if test="t.age!=null">and age=#{t.age}</if>
  <if test="t.sex!=null and t.sex!=''">and sex=#{t.sex}</if>
 </sql>
 <sql id="SetClause" >
  set 
  <trim suffixOverrides="," >
   <if test="id!=null">id=#{id},</if>
   <if test="name!=null">name=#{name},</if>
   <if test="pid!=null">age=#{age},</if>
   <if test="url!=null">sex=#{sex},</if>
  </trim>
 </sql> 
 <select id="queryList" resultType="Students">
  select <include refid="ColumnList"/> from students
 </select>
 <select id="queryTotal" parameterType="Students" resultType="Students">
  select <include refid="ColumnList" /> from students <include refid="WhereClause"/>
  <!-- (select <include refid="ColumnList"/> from t_account_cash t
    <include refid="WhereClauseQuery"/> group by to_char(t.add_time,'yyyy-mm-dd'),t.account_id) a --> 
 </select>
 <insert id="insertSheetData" useGeneratedKeys="true" parameterType="java.util.List"> 
  <!-- <selectKey resultType="long" keyProperty="id" order="AFTER"> 
   SELECT 
   LAST_INSERT_ID() 
  </selectKey> --> 
  insert into students (id,name,age,sex) 
  values 
  <foreach collection="list" item="item" index="index" separator="," > 
   (#{item.id},#{item.name},#{item.age},#{item.sex}) 
  </foreach> 
 </insert>
</mapper>

所有的代碼就是這些了，操作的時(shí)候需要注意的多是路徑的問(wèn)題。最復(fù)雜的就是BaseExcelController的操作，它做的事情就是解析上傳和創(chuàng)建下載excel文件。

執(zhí)行完之后的結(jié)果圖是這樣：

在數(shù)據(jù)庫(kù)查看上傳的excel表：

下載到D:\tomcat\tomcat6.0.32\webapps\ExcelHandleDemo\res\exportExcel文件夾下的excel表：

這里有一點(diǎn)不足的地方，我相信你已經(jīng)發(fā)現(xiàn)了，就是下載完excel表格之后，前端還沒(méi)有和業(yè)務(wù)對(duì)接上，沒(méi)有相應(yīng)的提示來(lái)告訴操作人執(zhí)行結(jié)果，只能通過(guò)代碼設(shè)置好的路徑去查看文件夾下是否有下載的excel文件，

不過(guò)這都是細(xì)節(jié)問(wèn)題，相信難不倒聰明的各位。

總結(jié)

以上所述是小編給大家介紹的Java對(duì)Excel表格的上傳和下載處理方法，希望對(duì)大家有所幫助，如果大家有任何疑問(wèn)歡迎給我留言，小編會(huì)及時(shí)回復(fù)大家的！
