Spring Boot Redis Cache @CachePut is not updating the cache

Question

    @Cacheable(cacheNames = "BooksCache", key = "#id")
    public Book findById(long id) {
        LOGGER.info("Fetching Book From DB For BookId: {}", id);
        return bookRepository.findById(id).orElse(null);
    }

Cacheable is working fine but when we add a new book or update the existing book cache is not updating

Here is the code for saveOrUpdate() and I have used @CachePut to update the cache but that was not working, Database is getting updated but cache is not updating

    @Transactional
    @CachePut(cacheNames = "BooksCache", key = "#book.id")
    public Book saveOrUpdateBook(Book book) {
        return bookRepository.save(book);
    }

I have tried @EnableTransactionManagement along with @Transactional Annotation. I have also tried spring boot starter cache instead of redis cache, But that was not working

Answer 1

You must call @Cachable- methods from another class. Otherwise the cache proxy will not work and the cache doesn't change/trigger.
