Spring不将JSON数组转换为用户定义对象的列表

Question

所以我有一个输入Json数据 -

[
  {
    "Id": "30B05CEC6808F81C7A8B",
    "eventType" :"TestEventType"
  }
]

包装类 -

public class CancelSeatEventDtoWrapper {

    List<CancelSeatEventDto> cancelSeatDtoList;

    public List<CancelSeatEventDto> getCancelSeatDtoList() {
        return cancelSeatDtoList;
    }

    public void setCancelSeatDtoList(List<CancelSeatEventDto> cancelSeatDtoList) {
        this.cancelSeatDtoList = cancelSeatDtoList;
    }
}

和POJO

public class CancelSeatEventDto {

    private String eventType, Id;

    public String getEventType() {
        return eventType;
    }

    public void setEventType(String eventType) {
        this.eventType = eventType;
    }

    public String getId() {
        return Id;
    }

    public void setId(String Id) {
        this.Id = Id;
    }
}

在Spring控制器中，其中一个方法有 -

@RequestMapping(value = "/teams/id.do", method = RequestMethod.DELETE)
@ResponseBody
public String deleteId(@RequestBody CancelSeatEventDtoWrapper jsonValue)

运行后，我收到400 Bad Request错误。 任何想法都错了吗？
