Service层

@Override
  public void export(Long sblsh, String excelName, OutputStream out) {
    try {
      // 第一步，创建一个webbook，对应一个Excel文件 
      HSSFWorkbook wb = new HSSFWorkbook();
      //生成一个表格 
      HSSFSheet sheet = wb.createSheet(excelName); 
      // 第三步，在sheet中添加表头第0行
      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 = row.createCell(0);
      cell.setCellStyle(style);
      
      Byte kjzz = qyjbxxMapper.getKjzz(sblsh);
      List record = this.selectBySblsh(sblsh);
 this.insertData(wb, sheet, row, record, out);
      }
    } catch (Exception e) {
      logger.info(e.getMessage());
    }
  }
  
  
  private void insertData(HSSFWorkbook wb,HSSFSheet sheet,HSSFRow row,List record,
      OutputStream out){
    try {
      row = sheet.createRow(1);
      for(int i=0;i

Controller



@RequestMapping("/export")
  public void export(Long sblsh, HttpServletRequest request, HttpServletResponse response){
    response.setContentType("octets/stream");
    String excelName = "文件名";
    try {
      response.addHeader("Content-Disposition", "attachment;filename="+new String(excelName.getBytes("gb2312"), "ISO8859-1" )+".xls");
      OutputStream out = response.getOutputStream();
      aService.export(sblsh,excelName ,out);
    } catch (Exception e) {
      e.printStackTrace();
    }
  }
