I have an entity with a relation to another one:
public class MyEntity {
@Id
@GeneratedValue
@Column(name = "id", nullable = false)
private UUID id;
@Column(name = "deleted", nullable = false)
private Boolean deleted = false;
@ManyToMany
@JoinTable(name = "feature_assignment",
joinColumns = @JoinColumn(name = "my_entity_id"),
inverseJoinColumns = @JoinColumn(name = "feature_id"))
private List<MyEntityFeature> myEntityFeatures;
and I have a perfectly working repository:
public interface MyEntityRepository extends JpaRepository<MyEntity, UUID>,
JpaSpecificationExecutor<MyEntity> {
Optional<MyEntity> findByIdAndDeletedIsFalse(UUID id);
}
But when I extend EntityGraphJpaSpecificationExecutor in my repository, it seems like it can't recognize former repository methods without entity graphs, even though the repository is still implementing the findById method. I get the following exception:
Caused by: java.lang.IllegalArgumentException: Failed to create query for method public abstract java.util.Optional com.cosium.spring.data.jpa.entity.graph.repository.EntityGraphJpaSpecificationExecutor.findOne(org.springframework.data.jpa.domain.Specification,com.cosium.spring.data.jpa.entity.graph.domain.EntityGraph)!

My pom.xml contains the following dependencies:
<dependency>
<groupId>com.cosium.spring.data</groupId>
<artifactId>spring-data-jpa-entity-graph</artifactId>
<version>2.5.0</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
Can anyone explain why this is happening? And how can I fix this error? Is it mandatory to override the findOne method after implementing EntityGraphJpaSpecificationExecutor?
