Why Jackson ObjectMapper give me this error converting JSON field into a Date object? Can not deserialize value of type java.util.Date from String

Tags: , , , ,



I have this JSON object:

{
    "dateTime": "2020-06-13 20:00:15",
    "timeStampMs": "130",
    "sensor001DV": "37.2",
    "sensor002DV": "40.5"
    .................................
    .................................
    .................................
}

that have to be mappend on this DTO class:

public class Trend002DTO {

    private Date dateTime;
    private int timeStampMs;
    private Timestamp timeStamp;

    private Double sensor001DV;
    private Double sensor001DV;
    ....................................
    ....................................
    ....................................
}

To do this mapping I am using Jackson ObjectMapper, in this way:

@Override
public int insertTrend(String trendTableName, Map<String, Object> jsonTrendInfo) {  
    Trend002DTO trend002DTO = mapper.convertValue(jsonTrendInfo, Trend002DTO.class);
    System.out.println("trend002DTO: " + trend002DTO.toString());

    return 0;
}

When I try to map the JSON dateTime field with the Date dateTime in my DTO class I am obtaining the following exception message:

As you can see the value of the dateTime field into my JSON document is 2020-06-13 20:00:15 (it have to contains the date and the time). I suspect that this is not in the correct format.

How can I solve the issue? Have I to change the format into my JSON object or have I to set some Jackson configuration?

Answer

Use @JsonFormat to deserialize for your format.

@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd HH:mm:ss")
private Date dateTime;

You can specify timezone also like timezone = "IST" in the annotation or as default timezone like timezone = JsonFormat.DEFAULT_TIMEZONE

As your JSON string format is different than the default format you have to specify the format.

I recommend you don’t use Date. This class is poorly designed and long outdated. Use LocalDateTime from java.time API
