"No property [repositoryMethod] found for type [entity]!"

[netmikey]

I'm trying to integrate your extension into my project but I'm having some trouble: whenever I add a method with a signature containing EntityGraph to my repository, I'm getting the error mentioned in the title.

For example, I have an interface CrudRepository I created. It is similar to Spring Data JPA's CrudRepository with the exception that it returns Optional<T> for single element find methods. I added the following declaration:

Optional<T> findOne(ID id, EntityGraph graph);

And I'm getting the following error at application startup (MyEntityRepository interface extends CrudRepository):

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'myEntityRepository': Invocation of init method failed; nested exception is org.springframework.data.mapping.PropertyReferenceException: No property findOne found for type MyEntity!

Your extension just has to be on the classpath for it to work, right? What could I be doing wrong?

Hello @netmikey ,

It looks like you didn't follow the full Quick start section of the documentation. As stated in this section, point 2, you must tell Spring Data to use this library repository factory bean.

[netmikey]

OMG, my bad, I totally missed the documentation links in the version table, so I though your library would be auto-discovered by spring (boot) magic, sorry!

[reda-alaoui]

It's ok ;)
