1、导入jar包

<dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>poi</artifactId>
            <version>3.5-FINAL</version>
        </dependency>

2、编写工具类

复制代码
package utils;

import org.apache.poi.hssf.usermodel.HSSFCell;
import org.apache.poi.hssf.usermodel.HSSFCellStyle;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;

public class ExcelUtil {
    
    public static HSSFWorkbook getHSSFWorkbook(String sheetName,String []title,String [][]values, HSSFWorkbook wb){
         // 第一步,创建一个webbook,对应一个Excel文件  
        if(wb == null){
            wb = new HSSFWorkbook();
        }
        // 第二步,在webbook中添加一个sheet,对应Excel文件中的sheet  
        HSSFSheet sheet = wb.createSheet(sheetName);  
        // 第三步,在sheet中添加表头第0行,注意老版本poi对Excel的行数列数有限制short  
        HSSFRow row = sheet.createRow(0);  
        // 第四步,创建单元格,并设置值表头 设置表头居中  
        HSSFCellStyle style = wb.createCellStyle();  
        style.setAlignment(HSSFCellStyle.ALIGN_CENTER); // 创建一个居中格式  
        
        HSSFCell cell = null;  
        //创建标题
        for(int i=0;i<title.length;i++){
            cell = row.createCell(i);  
            cell.setCellValue(title[i]);  
            cell.setCellStyle(style);  
        }
        //创建内容
        for(int i=0;i<values.length;i++){
            row = sheet.createRow(i + 1); 
            for(int j=0;j<values[i].length;j++){
                 row.createCell(j).setCellValue(values[i][j]);
            }
        }
        
       return wb;
    }
    
    
}
复制代码

3、导入表格信息

复制代码
package mvc.controller;

import java.io.OutputStream;
import java.io.UnsupportedEncodingException;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.List;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletResponse;

import mvc.model.Feedback;
import mvc.model.JResponse;
import mvc.model.apis.DownloadExcel;
import mvc.service.IAppInfoService;
import mvc.service.IBusinessService;

import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;

import com.prize.utils.StringUtil;

import utils.ExcelUtil;

@Controller
@RequestMapping(value="/excel/*")
public class ExcelController {
    
    @Resource
    private IAppInfoService appinfoService;
    
    @Resource
    private IBusinessService businessService;

    @RequestMapping(value = "exportfeedback")
    @ResponseBody
    public JResponse exportFeedBack(HttpServletResponse response,
            @RequestParam(value="query", required=false) String searchText,
            @RequestParam(value="type", required=false) String strType,
            @RequestParam(value="startDate", required=false) String startDate,
            @RequestParam(value="endDate", required=false) String endDate){
        
        String fileName = "反馈明细"+System.currentTimeMillis()+".xls"; //文件名 
        String sheetName = "反馈明细";//sheet名
        
        String []title = new String[]{"Id","导航图标","反馈类型","内容","联系方式","应用Id","应用版本","反馈时间"};//标题
        
        List<Feedback> list = appinfoService.getAllFeedbackForExcel(searchText, strType, startDate, endDate);//内容list
        
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        
        String [][]values = new String[list.size()][];
        for(int i=0;i<list.size();i++){
            values[i] = new String[title.length];
            //将对象内容转换成string
            Feedback obj = list.get(i);
            values[i][0] = obj.getId()+"";
            values[i][1] = obj.getFiles();
            values[i][2] = obj.getFbType();
            values[i][3] = obj.getContent();
            values[i][4] = obj.getContactInfo();
            values[i][5] = obj.getAppId();
            values[i][6] = obj.getVersionName();
            values[i][7] = sdf.format(obj.getCreateTime());
            
        }
        
        HSSFWorkbook wb = ExcelUtil.getHSSFWorkbook(sheetName, title, values, null);
        
        //将文件存到指定位置  
        try {  
             this.setResponseHeader(response, fileName);  
             OutputStream os = response.getOutputStream();  
             wb.write(os);  
             os.flush();  
             os.close();  
        } catch (Exception e) {  
             e.printStackTrace();  
        }  
        return JResponse.success("ok");
    }
    
     public void setResponseHeader(HttpServletResponse response, String fileName) {  
         try {  
              try {  
                   fileName = new String(fileName.getBytes(),"ISO8859-1");  
              } catch (UnsupportedEncodingException e) {  
                   // TODO Auto-generated catch block  
                   e.printStackTrace();  
              }  
              response.setContentType("application/octet-stream;charset=ISO8859-1");  
              response.setHeader("Content-Disposition", "attachment;filename="+ fileName);  
              response.addHeader("Pargam", "no-cache");  
              response.addHeader("Cache-Control", "no-cache");  
         } catch (Exception ex) {  
              ex.printStackTrace();  
         }  
    } 
}
复制代码
注意这里将 List<Feedback> list = appinfoService.getAllFeedbackForExcel(searchText, strType, startDate, endDate);//内容list 换成你自己的获取数据方法,将values二维数组导入util工具类方法中即可。

整体思路:将二维数组导入excel。


4、访问link即可,如:XXX/excel/exportfeedback

复制代码
<button id="js-export" type="button" class="btn btn-primary">导出Excel</button>


$('#js-export').click(function(){ window.location.href="/xxx/excel/exportfeedback?type="+$('#type').val()+"&startDate="+$('#table_start_date').val()+"&endDate="+$('#table_end_date').val(); });
