All Implemented Interfaces:

Serializable

public class NonUniqueResultException
extends DataException

This exception is raised when execution of a repository method with a singular return type finds multiple results.

This error can be circumvented by applying the @First annotation to a repository Find or Query method to explicitly request that at most one result be returned. Alternatively, if using the Query by Method Name pattern, the findFirst... method name pattern can be used to explicitly request that at most one result be returned.
