在糖尿病患者信息管理系统中，导入病人信息功能！form表单提交数据（Excel文件），在后台得不到file文件，解决方法：
private File filePath; //文件
private String fileName; //文件名
private String fileType; //文件类型
注：上面filePath必须有，否则下面得到filePath为空！
/**
* 导入病人信息,并且插入用户信息
*/
public String importPatient() throws Exception {
if (filePath != null) {
FileInputStream fis = new FileInputStream(filePath);
Workbook readWb = Workbook.getWorkbook(fis);
// 得到sheet
Sheet readSheet = readWb.getSheet(0);
// 得到多少列
int rsColumns = readSheet.getColumns();
// 得到多少行
int rsRows = readSheet.getRows();
// 单元格
Cell cell;
// 实例化病人对象
Patient patient = new Patient();
SysUser sysUser = new SysUser();
Map<Integer, String> map = new HashMap<Integer, String>();
for (int i = 1; i < rsRows; i++) {
for (int j = 0; j < rsColumns; j++) {
cell = readSheet.getCell(j, i);
map.put(j, cell.getContents());
}
UUID uuid = UUID.randomUUID();
String patientId = uuid.toString();
patient.setId(patientId);
//用户信息
sysUser.setId(uuid.toString());
sysUser.setUserName(map.get(5));
sysUser.setPassword(md5keyBean.getkeyBeanofStr("123456"));
sysUser.setNickName(map.get(1));
sysUser.setPhone(map.get(5));
//1：默认不锁定；0：锁定
sysUser.setStatus("1");
//角色id
List<SysRole> sysRoles = sysRoleService.findAllSysRoles();
if(sysRoles.size()>0) {
for (int j = 0; j < sysRoles.size(); j++) {
if("病人".equals(sysRoles.get(j).getName())) {
sysUser.setSysRole(sysRoles.get(j));
}
}
}
//病人id
sysUser.setFlagId(patientId);
sysUser.setCreateTime(new Date());
sysUserService.saveSysUser(sysUser);
patient.setNumber(map.get(0));
patient.setRealName(map.get(1));

jsp代码：

FileInputStream是InputStream的子类，不能直接转换，不过FileInputStream可当做InputStream来使用。
该批量导入和幼儿园管理系统导入不太一样！
