I have such string:
{
"debug":"false",
"switchTime":"2017-04-12 17:04:42.896026"
}
I'm trying to get object in such approach:
new ObjectMapper().readValue(string, MyObject.class);
And MyObject class:
class MyObject {
private Boolean debug;
private Timestamp switchTime;
//...getters, setters, constructors
}
I have such exception:
com.fasterxml.jackson.databind.exc.InvalidFormatException:
Can not deserialize value of type java.sql.Timestamp from String
"2017-04-12 17:04:42.896026": not a valid representation (error:

{"debug":"false", "switchTime":"2017-04-12 17:04:42.896026"};
I don't understand why...If i use in debug mode Timestamp.valueOf() with "2017-04-12 17:04:42.896026" - i have success
I think you need to set the expected date/time format using @JsonFormat annotation as shown below.
class MyObject {
private Boolean debug;
@JsonFormat(pattern="yyyy-MM-dd HH:mm:ss.SSS")
private Timestamp switchTime;
//...getters, setters, constructors
}
You can also set timezone as @JsonFormat(pattern="yyyy-MM-dd HH:mm:ss.SSS",timezone="PST")
I faced the similar problem when I was using lombok in the POJO class which has @Builder and @Value annotations
I have also added the annotation AllArgsConstructor and then it is working fine with my custom deserializer code
The value that you see in debug mode is "toString()" version of actual value of timestamp, so don't rely on what you inspect in debug mode. You can use @JsonFormat annotation that helps you to convert your timestamp with specified format. You need to take care of timezones also while converting!
