In order to make AliasToBeanResultTransformer work properly you need to use proper alias names in yourquery. If the property name in your StudentDto class is name, you should useselect student.name as name; using select student.name as n will again throw exception. The alias names that you are using in the query should be same as the property names in your DTO class.
