java - Spring MVC how to handle Joda Data Types as JSON -

i'm starting new spring mvc project. i'm using jpa entities mapping. had entity name account datetime field annotated followed:

@entity public class account implements serializable{     @id     @generatedvalue     private long id;     @temporal(temporaltype.timestamp)     private date openintime;     .......... } 

and entity client date field followed

@entity public class client {     @id     @generatedvalue     private long id;     private string firstname;     private string lastname;     @temporal(temporaltype.date)     private date birthdate; 

}

in spring-mvc controller, find account id , return followed

@requestmapping(value = "/find", method = requestmethod.get, produces = "application/json") public responseentity<?> findaccountbyid(@requestparam("accountid") long accountid) {     account accountfound = accountservice.findbyid(accountid);     responseentity<account> responseentity = new responseentity<account>(accountfound, httpstatus.ok);     return responseentity; } 

but, when saved account object date "2016-12-07 12:00:00", , then, try retrieve it, date i'm getting on client side "1481108400000"

so decide use jodatime instead of java.util.date (hoping solve problem)

i have configure in spring-mvc xml dispatcher file dateformatter. xml file:

but i'm still getting , error : prefix "p" attribute "p:indentoutput" associated element type "bean" not bound

you must declare p xml namespace xmlns:p="http://www.springframework.org/schema/p" in <beans> element:

<beans xmlns="http://www.springframework.org/schema/beans"     xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"     xmlns:p="http://www.springframework.org/schema/p"     ... <other namespaces> ... > 

after that, jodamodule jackson should automatically format jodatime types.
