如果是excel，需要将数据读入数据库的话，后台如下
public String upload(DrlsRequest request, MultipartFile file, ModelMap map) throws IOException {
InputStream in=file.getInputStream();
// // 得到工作表
Workbook book = WorkbookFactory.create(in);
// // 得到第一页
Sheet sheet = book.getSheetAt(0);
// // 得到第一面的所有行
Iterator<Row> row = sheet.rowIterator();
// 得到第一行，也就是标题行
Row title = row.next();
// 得到第一行的所有列
Iterator<Cell> cellTitle = title.cellIterator();
// 将标题的文字内容放入到一个map中。
Map<Integer, String> titlemap = new HashMap<Integer, String>();
List<String> cellNameList = new ArrayList<>();
// 从标题第一列开始
int i = 0;
// 循环标题所有的列
while (cellTitle.hasNext()) {
Cell cell = cellTitle.next();
String value = (cell.getStringCellValue() == null ? cell.getStringCellValue()
: cell.getStringCellValue().trim());
titlemap.put(i, value);
cellNameList.add(value);
i = i + 1;
}
while (row.hasNext()) {
// 标题下的第一行
Row rown = row.next();
// 行的所有列
Iterator<Cell> cellbody = rown.cellIterator();
// 得到传入类的实例
T tObject = pojoClass.newInstance();
int k = 0;
// 遍历一行的列
while (cellbody.hasNext()) {
Cell cell = cellbody.next();
// 这里得到此列的对应的标题
String titleString = (String) titlemap.get(k);
// 如果这一列的标题和类中的某一列的Annotation相同，那么则调用此类的的set方法，进行设值
if (fieldSetMap.containsKey(titleString)) {
Method setMethod = (Method) fieldSetMap.get(titleString);
// 得到setter方法的参数
Type[] ts = setMethod.getGenericParameterTypes();
// 只要一个参数
String xclass = ts[0].toString();
if (fieldSetConvertMap.containsKey(titleString)) {
fieldSetConvertMap.get(titleString).invoke(tObject, cell.getStringCellValue());
} else {
invokeByType(tObject, cell, setMethod, xclass);
}
}
// 下一列
k = k + 1;
}
dist.add(tObject);
}
}
