Spring mvc 下导出Excel文件

参考了网上资料，实现Spring mvc 下Excel导出 ，如有更好方法请大家拍砖

1.新建类继承AbstractExcelView

import java.io.OutputStream;
import java.util.Map;
import javacommon.util.MyUtils;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
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;
import org.springframework.web.servlet.view.document.AbstractExcelView;
public class ViewExcel extends AbstractExcelView {
	@Override
	protected void buildExcelDocument(Map<String, Object> obj,
			HSSFWorkbook workbook, HttpServletRequest request, HttpServletResponse response)
			throws Exception {
		HSSFSheet sheet = workbook.createSheet("list");  
        sheet.setDefaultColumnWidth((short) 12);  
        HSSFCell cell = getCell(sheet, 0, 0);  
        setText(cell, "Spring Excel test");  
        HSSFCellStyle dateStyle = workbook.createCellStyle();  
        //dateStyle.setDataFormat(HSSFDataFormat.getBuiltinFormat("mm/dd/yyyy"));  
        cell = getCell(sheet, 1, 0);  
        cell.setCellValue("日期：2008-10-23");  
        //cell.setCellStyle(dateStyle);  
        getCell(sheet, 2, 0).setCellValue("测试1");  
        getCell(sheet, 2, 1).setCellValue("测试2");
        HSSFRow sheetRow = sheet.createRow(3);  
        for (short i = 0; i < 10; i++) {  
            sheetRow.createCell(i).setCellValue(i * 10);  
        }  
        String filename = "测试.xls";//设置下载时客户端Excel的名称   
        filename = MyUtils.encodeFilename(filename, request);//处理中文文件名
        response.setContentType("application/vnd.ms-excel");   
        response.setHeader("Content-disposition", "attachment;filename=" + filename);   
        OutputStream ouputStream = response.getOutputStream();   
        workbook.write(ouputStream);   
        ouputStream.flush();   
        ouputStream.close();   
	}
}

 

处理中文文件名的方法：

/** 
     * 设置下载文件中文件的名称 
     *  
     * @param filename 
     * @param request 
     * @return 
     */  
    public static String encodeFilename(String filename, HttpServletRequest request) {  
      /** 
       * 获取客户端浏览器和操作系统信息 
       * 在IE浏览器中得到的是：User-Agent=Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; Maxthon; Alexa Toolbar) 
       * 在Firefox中得到的是：User-Agent=Mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv:1.7.10) Gecko/20050717 Firefox/1.0.6 
       */  
      String agent = request.getHeader("USER-AGENT");  
      try {  
        if ((agent != null) && (-1 != agent.indexOf("MSIE"))) {  
          String newFileName = URLEncoder.encode(filename, "UTF-8");  
          newFileName = StringUtils.replace(newFileName, "+", "%20");  
          if (newFileName.length() > 150) {  
            newFileName = new String(filename.getBytes("GB2312"), "ISO8859-1");  
            newFileName = StringUtils.replace(newFileName, " ", "%20");  
          }  
          return newFileName;  
        }  
        if ((agent != null) && (-1 != agent.indexOf("Mozilla")))  
          return MimeUtility.encodeText(filename, "UTF-8", "B");  
    
        return filename;  
      } catch (Exception ex) {  
        return filename;  
      }  
    } 

 

2接下来在你的下载 Controller里面返回ModelAndView 即可

/**
    * 导出Excel
    * @param model
    * @param projectId
    * @param request
    * @return
    */
   @RequestMapping(value="/dcExcel",method=RequestMethod.GET)
	public ModelAndView toDcExcel(ModelMap model, HttpServletRequest request){
	   List list = new ArrayList();  //测试数据没有用到
       Map map = new HashMap();  
       list.add("test1");  
       list.add("test2");  
       map.put("list", list);  
       ViewExcel viewExcel = new ViewExcel();  
       return new ModelAndView(viewExcel, model); 
   }

 

代码很简单，只实现下载，关于Excel 格式数据方面请参考 poi 框架
