杰克逊无法解析List <long> </long>

Question

杰克逊将List<Long>解析为List<Integer>，因此我得到ClassCastException。其中一个解决方案是将参数作为List<String>，但我不想这样做。有人可以建议我另类吗？

@RequestMapping(value = "/device/deleteNote", produces = "application/json", method = RequestMethod.POST)
@ResponseBody
public ResponseEntity<?> deleteNotification(@RequestBody ArrayList<Long> notificationIdListParam) {
    ....
}

Answer 1

试试这个

final static ObjectMapper mapper = new ObjectMapper();

final List<Obj> instance = mapper.readValue(json, new TypeReference<List<Obj>>(){});
