Spring 4 ZoneDateTime Restful recursive output

Question

I am new on Java 8 and Spring 4 i have tried to implement spring boot with module (Spring boot web, Spring boot jpa) i have tried to implement JpaAuditing on my entity with the following code:

//AbstractAuditedEntity.class
@MappedSuperclass
public class AbstractAuditedEntity  {

@CreatedBy
@Column(name = "CREATED_BY")
private String createdBy;
//    @Type(type="org.joda.time.contrib.hibernate.PersistentDateTime")

@CreatedDate
@DateTimeFormat(iso = DateTimeFormat.ISO.DATE_TIME)
@Column(name = "CREATED_DATE")
//    @Type(type = "org.jadira.usertype.dateandtime.joda.PersistentDateTime")
private ZonedDateTime createdDate;
@LastModifiedBy
@Column(name = "LAST_MODIFIED_BY")
private String lastModifiedBy;
//    @Type(type="org.joda.time.contrib.hibernate.PersistentDateTime")
@DateTimeFormat(iso = DateTimeFormat.ISO.DATE_TIME)
@LastModifiedDate
@Column(name = "LAST_MODIFIED_DATE")
//    @Type(type = "org.jadira.usertype.dateandtime.joda.PersistentLocalDateTime")
private ZonedDateTime lastModifiedDate;
/*setter getter are omitted*/

} and the User entity with the following code :

@Entity
@Table(name = "common_user")
public class User extends AbstractAuditedEntity {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "ID")
private Long id;
/*other fields are omitted*/
}

and my controller :

@RestController
public class UserCtrl {
@Autowired
UserRepository userRepository;

@RequestMapping(value = "/user", method = RequestMethod.GET)
@ResponseBody
public User index() {
    User one = userRepository.findOne(1L);
    return one;

}
}

the result is of field createdDate and lastModifiedDate are recursive :(

How to format ZoneDateTime in the Restful ?thanks before

That's not actually recursive; you can see for yourself by posting that json string into http://jsonformatter.curiousconcept.com/.

If you want to use ZonedDateTime and you don't want all of its properties converted to JSON, you might add @JsonIgnore to the field and then adding getters for each field that you want. For example:

@JsonIgnore
@CreatedDate
@DateTimeFormat(iso = DateTimeFormat.ISO.DATE_TIME)
@Column(name = "CREATED_DATE")
private ZonedDateTime createdDate;

public Month getMonthCreated(){
    return createdDate.getMonth();
}
