how to represent a list of entity values in JSON object

Question

I have a list of records in a entity type ,i had a confusion the way how to represent in column wise list or each of record as a json object,that means list of JSON Objects.

::Explanation ::

Here firstName , secondName , thirdName are column names . Need To Represent Like this format

__ {{firstName:Rec1,secondName:Rec1,thirdName:Rec1},{firstName:Rec2,secondName:Rec2,thirdName:Rec2}...n}__

But i approached like

_ _{firstName:[Rec1,Rec2,Rec3...],secondName:[Rec1,Rec2,Rec3...],thirdName:[Rec1,Rec2,Rec3...]},__

When i tried to pass as a entity type means it shows like

 __{"ServiceData":[com.aiway.eea.ejb.to.student.ParentStudentDetailsTO@8b0db2,com.aiway.eea.ejb.to.student.ParentStudentDetailsTO@1304967]}__

Please Help me to solve this...

Answer 1

we not able to pass as a entity type,we need Transfer Object to convert from ENTITY to JSON object,if List entityType means then Use List JSONObject and then put that List of JsonObject to another Json object like <"serviceData":JsonObject> then it will OUTPUT like {"ServiceData":[{"parentId":4009,"parentRelation":"Father","‌​parentNotification":‌​false,"parentOccupat‌​ion":"bussiness","pa‌​rentEducation":"mba"‌​,"parentName":"tharu‌​n"},{"parentId":4010‌​,"parentRelation":"M‌​other","parentNotifi‌​cation":false,"paren‌​tOccupation":"sdfsdf‌​","parentEducation":‌​"sdfsdfs","parentNam‌​e":"rakshitha"}]}
