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
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;
}
}
3、导入表格信息
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();
}
}
}
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
<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(); });
