5 mar 2024 · In this tutorial, we’ll explore the fundamentals of query hints in Spring Data JPA. These hints help to optimize database queries and potentially improve application performance by influencing the decision-making process of the optimizer.
To apply JPA query hints to the queries declared in your repository interface, you can use the @QueryHints annotation. It takes an array of JPA @QueryHint annotations plus a boolean flag to potentially disable the hints applied to the additional count query triggered when applying pagination, as shown in the following example:
