angulis.js：
$upload.upload({
url: url,
params: {
//providerid: $scope.institutionDetail.providerCode
},
file: $scope.files
}).success(function (response) {
//todo
})
.error(function (r) {
//todo
})
或者用ajax也行，主要是用于提交一个文件。
controler:
@SecurityAccess(menuNodes = "", open = true)
@RequestMapping(value = "/hcpms/madagascar/uploadSqlParameterExcel.do", method = RequestMethod.POST)
@ResponseBody
public IntegrityResponseBean uploadParameterExcel(
@ModelAttribute InterityBlackAddRequestVO vo,
HttpServletRequest request) {
//获取文件信息：
List<MultipartFile> files = getParameterExcelFileList(request);
//封装为自己的DTO
List<HcpmsBiEtlJobParamsDTO> list = this.findParameterExcelHcpmsBiEtlSqlDTO(files, user);
}
1、findParameterExcelHcpmsBiEtlSqlDTO 方法：
private List<HcpmsBiEtlJobParamsDTO> findParameterExcelHcpmsBiEtlSqlDTO(
List<MultipartFile> files, UserDetails user) {
List<HcpmsBiEtlJobParamsDTO> list = new ArrayList<HcpmsBiEtlJobParamsDTO>();
if (files != null && files.size() > 0) {
for (MultipartFile file : files) {
parseParameterExcelToDTO(file, list, user);
}
}
return list;
}
2、getParameterExcelFileList方法：
private List<MultipartFile> getParameterExcelFileList(
HttpServletRequest request) {
MultipartResolver resolver = new CommonsMultipartResolver(request
.getSession().getServletContext());
MultipartHttpServletRequest multiRequest = resolver
.resolveMultipart(request);
List<MultipartFile> files = multiRequest.getFiles("file");
return files;
}
3、parseParameterExcelToDTO方法：
private void parseParameterExcelToDTO(MultipartFile file,
List<HcpmsBiEtlJobParamsDTO> list, UserDetails user) {
String username = user.getUsername();
InputStream is = null;
try {
is = file.getInputStream();
String fileName = file.getOriginalFilename();
String fileType = fileName.substring(fileName.lastIndexOf(".") + 1,
fileName.length());
if ("xlsx".equals(fileType)) {
XSSFWorkbook wb = new XSSFWorkbook(is);
XSSFSheet childSheet = wb.getSheetAt(0);
// readExcel
readParameterExcelToBean(childSheet, username, list);
} else if ("xls".equals(fileType)) {
HSSFWorkbook wb = new HSSFWorkbook(is);
HSSFSheet childSheet = wb.getSheetAt(0);
// readExcel
readParameterExcelToBean(childSheet, username, list);
}
} catch (Exception e) {
HttpProcessUtil.processException(e);
} finally {
try {
if (is != null) {
is.close();
}
} catch (IOException e) {
}
}
}
4、readParameterExcelToBean方法：
private void readParameterExcelToBean(HSSFSheet childSheet,
String username, List<HcpmsBiEtlJobParamsDTO> list) {
int rowNum = childSheet.getLastRowNum();
// j=1 跳过head部分
for (int j = 1; j <= rowNum; j++) {
HSSFRow row = childSheet.getRow(j);
HcpmsBiEtlJobParamsDTO currentBean = this.getParameterDTOFromRow(
row, username);
if (null != currentBean) {
list.add(currentBean);
}
}
}
5、getParameterDTOFromRow方法：
private HcpmsBiEtlJobParamsDTO getParameterDTOFromRow(XSSFRow row,
String opertionUser) {
if (row == null) {
return null;
}
HcpmsBiEtlJobParamsDTO bean = new HcpmsBiEtlJobParamsDTO();
int cellNum = row.getLastCellNum(); // 每行有多少列(格)
for (int k = 0; k < cellNum; k++) {
if (row.getCell(k) == null) {
continue;
}
String value = row.getCell(k).toString();
if (!StringUtils.hasText(value)) {
continue;
}
// setBeanFir
setParameterBeanFir(bean, value, k);
}
return bean;
}
6、setParameterBeanFir方法：
private void setParameterBeanFir(HcpmsBiEtlJobParamsDTO bean, String value,
int k) {
if (k == 0) { //
bean.setParamsType(value);
}
if (k == 1) { //
bean.setJobCode(value);
}
if (k == 2) { //
bean.setParamsName(value);
}
if (k == 3) { //
bean.setParamsValue(value);
}
if (k == 4) { //
bean.setParamsInfo(value);
}
if (k == 5) { //
bean.setIsValid(value);
}
}
7、HcpmsBiEtlJobParamsDTO 实体类：
public class HcpmsBiEtlJobParamsDTO extends BaseDTO {
private static final long serialVersionUID = 1L;
// VARCHAR2(2) idEtlParameter
private String idEtlParameter;
// VARCHAR2(2) 参数类型(0:公有，1:私有)
private String paramsType;
// VARCHAR2(20) JOB编码
private String jobCode;
// VARCHAR2(20) 参数名称
private String paramsName;
// VARCHAR2(1024) 参数值(符合PL/SQL格式)
private String paramsValue;
// VARCHAR2(2) N 是否有效[0-有效，1-无效]
private String isValid;
// VARCHAR2(200) 参数说明
private String paramsInfo;
// VARCHAR2(100) N 创建人
private String createdBy;
// DATE N SYSDATE 创建时间
private Date dateCreated;
// VARCHAR2(100) N 修改人
private String updatedBy;
// DATE N SYSDATE 修改时间
private Date dateUpdated;
}
