Learn about restricting the scope of Spring Data repositories.
- [Instructor] Something not well documented … in the Spring Data website … but well followed in the community … is the read-only repository pattern. … It is a conceivable scenario where you want to … restrict the repository from invoking … certain default Crud repository methods. … We can accomplish this by creating … a no-repository bean interface. … So how do we do that? … First, we create a new interface and name it appropriately … read-only repository or write-only repository for example … and extend it from repository, not Crud repository. … Next we annotate the interface with @NoRepositoryBean. … This tells the Spring repository scanner … not to instantiate a class for this interface. … It's purely an interface and will remain so. … Lastly we add the signatures of the allowed methods. … The signature must exactly match the signature … of the permitted Crud repository method. … Now we are ready to extend from this repository. … In this example, we are restricting repository methods …
