No @Query over some methods in a few repositories

[mepox]

For example in this class: IUsersJpaRepository https://github.com/trebol-ecommerce/spring-boot-backend/blob/main/src/main/java/org/trebol/jpa/repositories/IUsersJpaRepository.java

There is no @query annotation before this method: Optional<User> findByName(String name);

However this method get called for example here in this class: UsersJpaCrudServiceImpl https://github.com/trebol-ecommerce/spring-boot-backend/blob/main/src/main/java/org/trebol/jpa/services/crud/UsersJpaCrudServiceImpl.java

In this method: UsersJpaCrudServiceImpl:

@Override
  public Optional<User> getExisting(UserPojo input) throws BadInputException {
    String name = input.getName();
    if (name == null || name.isBlank()) {
      throw new BadInputException("Invalid user name");
    } else {
      return userRepository.findByName(name);
    }
  }

I don't understand how it works without the @query annotation 😕

• If there is no @query then the method does nothing?
• Then why is it used?
• Or is it unimplemented yet?
• Or just left there by mistake?

I think its handled by the JPA or Spring Data by general..
Check this doc
https://docs.spring.io/spring-data/data-commons/docs/1.6.1.RELEASE/reference/html/repositories.html

Check example 1.4

"The JPA module supports defining a query manually as String or have it being derived from the method name."

I see, I didn't know this. 😄 Thanks!
