前言：
maven中需要添加依赖：
<dependency>
<groupId>jexcelapi</groupId>
<artifactId>jxl</artifactId>
<version>2.4.2</version>
</dependency>
public static void excleExport(OutputStream ouputStream, List<List<Object>> dataList) { try { WritableWorkbook book = Workbook.createWorkbook(ouputStream); WritableSheet sheet = null; // 列 Integer column = 0; // 行 Integer row = 0; // sheet Integer sheetIndex = 0; sheet = book.createSheet("sheet" + (sheetIndex + 1), sheetIndex); for (Integer index = 0; index < dataList.size(); index++) { row = index; for (Integer titleIndex = 0; titleIndex < dataList.get(index) .size(); titleIndex++) { String content = String.valueOf(dataList.get(index).get(titleIndex)); Label label = new Label(column, row, content); sheet.addCell(label); column++; } // 回归到第一列 column = 0; } book.write(); book.close(); ouputStream.flush(); ouputStream.close(); } catch (IOException e) { e.printStackTrace(); } catch (WriteException e) { e.printStackTrace(); } }
使用：
controller层：
@RequestMapping(value = "api/upload/excel/{type}", method = RequestMethod.GET)
@ResponseBody
public R LoadExcel(@PathVariable(value = "type") String type, HttpServletResponse response) {
try {
OutputStream outputStream = response.getOutputStream();
//设置响应类型
response.setContentType("application/vnd.ms-excel");
SimpleDateFormat sf = new SimpleDateFormat("yyyyMMddkkmmssSSS");
String filename = "Report" + sf.format(new Date());
//设置响应头
response.setHeader("Content-disposition", "attachment;filename=" + filename + ".xls");
byte[] bytes = tanantEMMService.exportExcel(type, outputStream);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return R.ok();
}
这一步最重要的就是设置响应类型和响应头，至于为啥。。。 因为我总是忘记咋设置！！！
public static void excleExport(OutputStream ouputStream, List<List<Object>> dataList) { try { WritableWorkbook book = Workbook.createWorkbook(ouputStream); WritableSheet sheet = null; // 列 Integer column = 0; // 行 Integer row = 0;
// sheet Integer sheetIndex = 0; sheet = book.createSheet("sheet" + (sheetIndex + 1), sheetIndex); for (Integer index = 0; index < dataList.size(); index++) {
row = index;
for (Integer titleIndex = 0; titleIndex < dataList.get(index) .size(); titleIndex++) { String content = String.valueOf(dataList.get(index).get(titleIndex)); Label label = new Label(column, row, content);
sheet.addCell(label); column++; } // 回归到第一列 column = 0; } book.write(); book.close(); ouputStream.flush(); ouputStream.close(); } catch (IOException e) {
e.printStackTrace(); } catch (WriteException e) {
e.printStackTrace(); }
}
