I am trying to map my native SQL result to my POJO, but it's returning an error. Here is the full stack trace:
Hibernate: SELECT * FROM members_tb where memberName like ?

//return membersDao.findByMemberName(memberName);
List<Members> members = null;
try {
session = HibernateUtil.getSessionFactory().openSession();
transaction = session.beginTransaction();
// Native query selecting all columns
Query query = session.createNativeQuery("SELECT * FROM members_tb where memberName like :memberName","MemberMapping")
.setParameter("memberName","%"+memberName+"%"); //named parameter binding
members = query.getResultList();
transaction.commit();
} catch (Exception e) {
e.printStackTrace();
} finally {
if (session != null) {
session.close();
}
}
// HibernateUtil.shutdown();
return members;
}
Please how do i do away with the error and design an appropriate constructor ??? Possibly if i don't have to load every column into the constructor although i want all columns mapped in the result.
回答1:
You will have to create a constructor for this.
Create a constructor in the class in which you have used SqlResultsetMapping and keep the variables in the constructor in the same sequence as you have kept them in the SqlResultsetMapping
回答2:
The listed columns are not in the same order as the constructor parameters.
Parameters Columns
========================= ==================
Long memberId memberId
Long dcaRegno dcaRegno
String memberName address
Long memberMobileNum age
Long memberHomePhoneNum areaId
String memberEmail birthday
String gender cellId
String department dca
String address department
Long cellId editor
Long areaId firstTime
String maritalStatus gender
String age maritalStatus
String birthday memberEmail
String firstTime memberHomePhoneNum
String secondTime memberMobileNum
String dca memberName
String note note
String editor secondTime
回答3:
please create this constructor in pojo class.As i can see mismatch between constructor
Members(Long memberId,Long dcaRegno,String address,String age,Long areaId,String birthday,Long cellId,String dca,String department,String editor,String firstTime,String gender,String maritalStatus,String memberEmail,Long memberHomePhoneNum,Long memberMobileNum,String memberName,String note,String secondTime)
hope this will work for you
