JPA Repository: javax.persistence.NonUniqueResultException: result returns more than one elements

Question

Using the below code I am unable to get the results of my query. Whether I use Map or Map I get the same error: javax.p

Answer 1

It appears that the problem was that Map<ContentType, Integer> does not have a promise of a unique index, so JPA doesn't like mapping to it. By using List<Map<ContentType, Integer>> instead, it works great!

Answer 2

Try this it works

keep your model in list

@RequestMapping(value="/deleteDriver/{id}" , method=RequestMethod.POST)
public ResponseEntity<Object> deleteDriver(@PathVariable("id") Integer id)
{
    List<Driver> delete_driver=adminService.getDriverById(id);
    Map<String,Object> response=new HashMap<>();


    if(delete_driver==null)
    {
        response.put("status", "Failure");
        return new ResponseEntity<Object>(response,HttpStatus.NO_CONTENT);
    }
    else
    {
        response.put("status", "Success");
        adminService.delete(delete_driver);
        return new ResponseEntity<Object>(response,HttpStatus.OK);
    }

}

then in your repository

@Override
public void delete(List<Driver> delete_driver) {

    driverRepository.delete(delete_driver);
}
