HI basant suppose if I want to save the list of product in Redis server for example in this video we are saving only one product can you share me for the list of products public Product save(Product product){ template.opsForHash().put(HASH_KEY,product.getId(),product); return product; }

[@TEAMPOWERHOUSE]

if any one know the answer

[@ramirolopezgomez8119]

​@@TEAMPOWERHOUSE something like that: public void saveAll(List product) { Map toSave = product.stream().collect(Collectors.toMap(Product::getId,Product::identity)); template.opsForHash().putAll(HASH_KEY,toSave); }

Hi, help me fix error. In Product.java, product.getId() has red line. ( in template.opsForHash().put(HASH_KEY,product.getId(),product)). I added all the four annotation you showed(@Data @AllArgsConstructor @NoArgsConstructor @RedisHash("Product")) to Product.jave. My pom.xml has lombok dependency. Can you help what could be the reason of this red line?

What IDE you are using ?

If you are using VSCode try downloading the "Lombok Annotations Support for VS Code" then reload the editor after installing. Lombok's @Data annotation should now be recognized.

Really good video Techie 👍. Can you also show us springboot webflux please?

[@jovangrgur3266]

A very unclear and rough explanation of using Redis with Spring Boot. This important basic things should be explained much better and you should explain all the steps, for example when you created RedisTemplate bean you didn't explain anything about serializers and why we use each of them. In this way you just only typed the code without any explanation which makes this tutorial useless for someone who is beginner or who learns Redis for the first time

[@sabihaakter4580]
