No property type found - spring

Question

I was working on a project but I got this no property type found error.
Please check my code and try to understand what the problem is.

my pom.xml and application.properties files are working OK so where can the problem be? Thanks...

Answer 1

I think the problem is in your repo:
public interface MesafeRepository extends JpaRepository<Mesafe, Long>{
public List<Mesafe> findByName(String name);
}
According to method findByName, your entity should have a property name, but there is no such property in Mesafe entity
You can just remove this method from repo, or add corresponding property to the entity
