项目背景：jersey框架，fastjson

<!-- 加入fastjson依赖包 -->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>1.1.37</version>
        </dependency>

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
 * @author alex

@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> 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
