Java – Jackson deserializes JSON with timestamp fields

I have this string:

{
   "debug":"false","switchTime":"2017-04-12 17:04:42.896026"
}

I try to get objects in this way:

new ObjectMapper().readValue(string,MyObject.class);

And MyObject classes:

class MyObject {
    private Boolean debug;
    private Timestamp switchTime;
    //...getters,setters,constructors
}

I have this 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:
Failed to parse Date value '2017-04-12 17:04:42.896026': 
Can not parse date "2017-04-12 17:04:42.896026Z": while it seems 
to fit format 'yyyy-MM-dd'T'HH:mm:ss.SSS'Z'',parsing fails (leniency? null))  at [Source:   
{"debug":"false","switchTime":"2017-04-12 17:04:42.896026"};

I don't understand why... If I use timestamp in debug mode Valueof () and "2017-04-12 17:04:42.896026" – I have succeeded

Solution

I think you need to use the @ jsonformat annotation to set the expected date / time format, as shown below

class MyObject {
  private Boolean debug;
  @JsonFormat(pattern="yyyy-MM-dd HH:mm:ss.SSS")
  private Timestamp switchTime;
  //...getters,constructors
}

You can also set the time zone to @ jsonformat (pattern = "yyyy MM DD HH: mm: SS. SSS", timezone = "PST")
