jar包引入
poi 3.16
poi-ooxml 3.16
poi-ooxml-schemas 3.16
commons-fileupload 1.3.1
commons-io 2.4
导出：
1前端用get请求，如window.location=""
/**导出*/
@RequestMapping(value ="/daoChu")
@ResponseBody
public void daoChu(HttpServletResponse response,@RequestParam(required =false) String surveyedName, @RequestParam(required =false) String surveyedIdcard, @RequestParam(defaultValue ="0") Integer investigationType, @RequestParam(required =false) String investigationName, @RequestParam(required =false, defaultValue ="1") Integer pageNumber, @RequestParam(required =false, defaultValue ="5") Integer pageSize) {
HSSFWorkbook hwb =new HSSFWorkbook();
SimpleDateFormat sdf =new SimpleDateFormat("yyyyMMddhhmmss");
String pattern = sdf.format(new Date());
HSSFSheet sheet = hwb.createSheet("考察" + pattern);
sheet.setDefaultColumnWidth((short)15);
HSSFCellStyle style = hwb.createCellStyle();
HSSFRow row = sheet.createRow(0);
String str ="被考察人姓名,被考察人身份证,被考察人单位,被考察人地区,考察类型,考察人姓名,考察人职位,考察内容,创建时间";
String[] heads = str.split(",");
if (null != heads && heads.length >0) {
for(int i=0;i
row.createCell(i).setCellValue(heads[i]);
}
}
//添加数据
Grid grid =investigationService.pageListInvestigationBean(surveyedName, surveyedIdcard, investigationType, investigationName, pageNumber, pageSize);
List list = grid.getRows();
for(int i=0;i
row = sheet.createRow(i+1);

row.createCell(6).setCellValue(list.get(i).getInvestigationPosition());
row.createCell(7).setCellValue(list.get(i).getInvestigationContent());
row.createCell(8).setCellValue(list.get(i).getTime());
}
OutputStream output;
try {
output = response.getOutputStream();
response.reset();
response.setHeader("Content-disposition", "attachment; filename=" + java.net.URLEncoder.encode("考察", "UTF-8") +".xls");
response.setContentType("application/msexcel");
hwb.write(output);
output.close();
}catch (IOException e) {
e.printStackTrace();
}
}
导入：前端form加入method="post" enctype="multipart/form-data"
/**导入*/
@RequestMapping(value ="/daoRu")
@ResponseBody
public void daoRu(HttpServletRequest request) {
CommonsMultipartResolver cmr =new CommonsMultipartResolver(request.getSession().getServletContext());

if (cmr.isMultipart(request)){
MultipartHttpServletRequest msr = (MultipartHttpServletRequest) request;
Iterator iter = msr.getFileNames();
if (iter.hasNext()){
file = msr.getFile(iter.next());
}
}
if (file ==null)return;
List> data =new ArrayList>();
FileUtil.ExcelFileToList(file, data);
if (null != data && data.size() >0) {
for (int i=1;i
List obj = data.get(i);
if (null != obj && obj.size() >0) {
for (Object o : obj) {
if (null == o) {
return;
}
}
InvestigationBean investigationBean =new InvestigationBean();
investigationBean.setSurveyedName(obj.get(0).toString());

}
}
}
}
