Since `LocalDateTime` is Java 8 date/time type, and since Jackson 2.x does not require Java 8 (runs on Java 6, compiles on Java 7), it does not provide support directly. You need to use Java 8 date/time module from: https://github.com/FasterXML/jackson-modules-java8/ and artifact name is `jackson-datatype-jsr310` (for Maven dependency or to get jar). Module is registered with ObjectMapper mapper = ...; mapper.registerModule(new JavaTimeModule()); Without adding this module databind just sees a weird POJO (with getters) and serializes it that way. -+ Tatu +- > > { > "id" : 10, > "name" : "name10", > "description" : "description10", > "updatedAt" : { > "nano" : 148000000, > "year" : 2018, > "month" : "JANUARY", > "dayOfMonth" : 10, > "dayOfWeek" : "WEDNESDAY", > "dayOfYear" : 10, > "hour" : 22, > "minute" : 26, > "second" : 54, > "monthValue" : 1, > "chronology" : { > "id" : "ISO", > "calendarType" : "iso8601" > } > }, > "createdAt" : { > "nano" : 148000000, > "year" : 2018, > "month" : "JANUARY", > "dayOfMonth" : 10, > "dayOfWeek" : "WEDNESDAY", > "dayOfYear" : 10, > "hour" : 22, > "minute" : 26, > "second" : 54, > "monthValue" : 1, > "chronology" : { > "id" : "ISO", > "calendarType" : "iso8601" > } > } > } > > How do I make updatedAt and createdAt as single string entry in resulting > json. > > -- > You received this message because you are subscribed to the Google Groups > "jackson-user" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > To post to this group, send email to [email protected]. > For more options, visit https://groups.google.com/d/optout. -- You received this message because you are subscribed to the Google Groups "jackson-user" group.
