Caused by: java.lang.IllegalArgumentException: Not a managed type: class com.deck.microFin.entity.UserMstr
    at org.hibernate.jpa.internal.metamodel.MetamodelImpl.managedType(MetamodelImpl.java:210)

@org.springframework.stereotype.Repository
public interface Repository extends JpaRepository<CompanyMstr, Long> {

我的实体类是这样的：

@MappedSuperclass
@Table(name = "user_mstr", schema = "admin")

public class UserMstr implements Serializable {

我错过了什么？
