Can not deserialize instance of com.entity.StudentDto out of START_ARRAY token

项目背景：jersey框架，fastjson

		
			com.alibaba
			fastjson
			1.1.37
		

1：对于json为String用{}包裹 中存在单个[{}]对象的，单独定义class用List定义接收

2: 存在数组的，定义字段为String[ ]接收；private String[] probeTemperatures;

 3：类定义

 * @note 	接收的json的参数类

@Data
public class VehInfoDto {
	
	private String id;
	private String reportDataId;
	private String vin;
	private String eventId;
	private String messageType;
	private int sequence;
	private String eventDateTimeUTC;
	private String createdDate;
	private String lastUpdatedDate;
	private CompleteVehicle completeVehicle;
	private Engine engine;
	private FuelCell fuelCell;
	private Gps gps;
	private LimitValue limitValue;
	private Warnings warnings;
	private List electricalMachine;//此class必须List
}

ps：今天天气不错，就开心把出问题并解决的json贴出来
