I have a type

type Dict {
...
updateUser: Int
...
}

public class DictEntity {
@Schema(

        name = "updateUser",
        nullable = true
    )
    private Long updateUser;

}

When the updateUser is null, the returned json is blank string "", how can I return null instead of ""?

{
          "code": " I am code",
          "createTime": "2024-08-07T23:08:07",
          "updateUser": "",
          "orgId": 1
        }

You seem to be using some framework - not sure what annoation @Schema is from? Can you expand more on that

Also your schema type is updateUser: Int yet your Java type is a Long and the Json value is String - that strikes me as weird but since I have no idea what framework the above is using its hard to know if thats expected or not
