Spring Data JPA - "No Property Found for Type" Exception

No property found for type... custom Spring Data repository

The problem here is that you are creating FilterRepositoryImpl but you are using it in UserRepository. You need to create UserRepositoryImpl to make this work.

Read this doc for more detail

Basically

public interface UserRepositoryCustom {
    List<User> filterBy(String role);
}

public class UserRepositoryImpl implements UserRepositoryCustom {
...
}

public interface UserRepository extends JpaRepository<User, String>, UserRepositoryCustom {
...
}

Spring Data 2.x update
This answer was written for Spring 1.x. As Matt Forsythe pointed out, the naming expectations changed with Spring Data 2.0. The implementation changed from the-final-repository-interface-name-with-an-additional-Impl-suffix to the-custom-interface-name-with-an-additional-Impl-suffix.

So in this case, the name of the implementation would be: UserRepositoryCustomImpl.

Spring Data JPA: No property found for type (Field name contains query method predicate keywords)

Look like In is a keyword used by Spring query derivation. So it expects a stored property which is In value provided in arguments.

https://docs.spring.io/spring-data/jpa/docs/current/reference/html/#appendix.query.method.predicate

You need to use @Query annotation to get what you want.

Spring Data JDBC: No such property found for type

Just remove the method getIngredients() and use findAll() (provided by the super interface) instead.

You should also remove the other methods, because they are already provided by the super interface

• save() <- provided by CrudRepository
• getById() <- CrudRepository provide Optional<T> findById(ID id);
• getIngredients <- CrudRepository provide Iterable<T> findAll();

Spring Boot JPA Query Error - No property '' found for type '' Exception

In BDProject you have property

private BDUser bdUser;

and in the repository you have:

public List<BDProject> findByUserID(String userID);

Error states that in BDProject you don't have property userID which is correct since you have bdUser.

Therefore, please change

findByUserID(String userID) to findByBdUserUserID(String userID)

spring data jpa - UsersRepository No property name found for type Users

Change your repository method name to

Optional<Users> findByUserName(String userName);

as you do not have property called name.

Couple of suggestions:

• Keep your entity class name as User instead of Users. (The entity class represents one record in the table which is basically an User )
• Let the variable userName be username. (if you go with this, then the repository method name would findByUsername.
