Spring Boot - Caching

Which of the following is the correct syntax to use @CachePut to update a cache named "users" with a key based on the method parameter id?

A@CachePut(cacheName = "users", key = "id")

B@CachePut(value = "users", key = "#id")

C@CachePut(name = "users", key = "id")

D@CachePut(cache = "users", key = "#id")

Step-by-Step Solution

Solution:

Step 1: Recall correct attribute names for @CachePut
The correct attribute for cache name is 'value' or 'cacheNames', and SpEL expressions for keys use '#'.
Step 2: Analyze each option's syntax
@CachePut(value = "users", key = "#id") uses 'value' and '#id' correctly. Others use incorrect attribute names or miss the '#' for SpEL.
Final Answer:
@CachePut(value = "users", key = "#id") -> Option B
Quick Check:
Use 'value' and '#param' for key in @CachePut [OK]

Quick Trick: Use 'value' for cache name and '#' before param in key [OK]
