I am getting this error when using spring data jpa

My Repository is defined as

public interface AuditTrailRepository extends CrudRepository<AuditTrail, Long>, JpaSpecificationExecutor<AuditTrail> {
	
	
	public List<AuditTrail> findByKey(String key);
	
	 @Query("select u from AuditTrail u where u.createdDate between :startDate and :endDate ")
	 List<AuditTrail> findByDateRange(@Param("startDate") Date startDate, @Param("endDate") Date endDate);
	 
	 @Query("select u from AuditTrail u where u.createdDate between :startDate and :endDate and key = :clientId ")
	 List<AuditTrail> findByDateRangeForClient(@Param("startDate") Date startDate, 
			 @Param("endDate") Date endDate,
			 @Param("ClientId") String clientId);
	 

}

My entity is

@Entity
@Table(name = "AUDIT_TRAIL")
public class AuditTrail extends BaseEntity {

	/**
	 * 
	 */
	private static final long serialVersionUID = -1647646453787027659L;
	private Long id;
	// ClientID from  
	private String key;
	private TaskType taskType;
	// Inbound / Outbound
	private FileActionType action;
	private String userName;
	private String message;
	private Date startTime;
    private Date endTime;

Any help appreciated.

The only thing that worked for me is to specify each class in the persistence.xml

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
             version="2.0">
   <persistence-unit name="spring-jpa" >
        <class>com.multiplan.edi.common.domain.AuditTrail</class>

   </persistence-unit>

</persistence>
