![]() This method is using the 'EEE MMM dd HH:mm:ss zzz yyyy' format to display the date and simply omits all milliseconds. It can be as simple as: Date d DateFormat.getDateInstance (). I have also tried catching that date string and parsing it using a SimpleDateFormat but failed since the exception occurs way before this logic. You are fooled by the () which uses Dates toString () method. Date-to-String conversion is a relatively complex parsing operation, not something you can do with a simple cast as you are trying. I could have written a JsonDeserializer and annotate the Date object with it, but since it is a Object within a HashMap how should i achieve this. Getting the old apis of conversion can be iso format and arguments. I understand that it had been a Date object. Apply the java can parse the desired format string. The problem is when date is given in the any date format (in my case zulu format) the jacksonjson converter is unable to parse it and throws error stating cannot parse the input string. So far, I am able to succeed in converting strings, numbers but Date is causing trouble. Now, I have to convert the object into their respective run time data types according to the business logic. If your real goal is to serialize a Date object for some kind of custom made persistence or data transfer, a simple solution would be: Date d new Date () long l d.getTime () Date theSameDate new Date (l) FYI: The troublesome Date Class is now legacy, replaced by Instant and the other java.time classes. To generate a String from a java. A date-time object can generate a String to represent its value, but that String is separate and distinct from the date-time object. To convert String objects to LocalDate and LocalDateTime objects, the String must represent a valid date or time according to ISOLOCALDATE or ISOLOCALDATETIME. ![]() This dynamic attributes is defined as HashMap attr = new HashMap() Do not confuse a String of text describing the value of a date-time with the date-time itself. T he Date-Time API provides parse() methods for parsing a String that contains date and time information. I have scenario where i need to store the dynamic attributes into the database in the form of HashMap given by the user using a rest service.
