JavaWeb 中 Service和Controller层返回值需不需要严格的泛型

[qq_41910048]

public ResponseMessage<List<Map<String,String>>> getTodayStudentOff(String username){
List<Map<String,String>> studentOffs = new ArrayList<Map<String,String>>();
try{
SimpleDateFormat sf = new SimpleDateFormat();
String nowTime = sf.format(new Date());
studentOffs = studentDao.getTodayAllStudentoffByStudentid(username,nowTime);
if(studentOffs.isEmpty()){
throw new Exception("今天没有你的假条");
}else{
return new ResponseMessage(true,studentOffs,"OK");
}
}catch (Exception e){
return new ResponseMessage(false,studentOffs,e.getMessage());
}
}
诸如此类一系列的List<Map>等等，我觉得有必要吗，处理不好json无法解析?
我对这个不是很有经验，至少php是不用管的
