SpringCache: Understanding the Usage of @CacheEvict Annotation in Java

The @CacheEvict annotation in Java's SpringCache framework serves the purpose of clearing cached information. Let's delve into its key parameters and functionalities. The 'value' parameter designates the specific cache information keys to be deleted, similar to the 'key' parameter in @Cacheable. It combines with 'value' to generate the cache. The 'allEntries' parameter signifies whether to remove the entire cache specified in 'value.' Its default value is false. When set to true, all caches corresponding to 'value' will be cleared. When set to false, only the cache for the specified key will be deleted. The 'beforeInvocation' parameter determines whether to perform cache clearance before the annotated method is executed. If set to true, the cache will be cleared regardless of the method's success, ensuring effective cache clearance. The default value is false, meaning the cache clearance won't be executed unless set to true. This concludes our brief exploration of @CacheEvict in Java's SpringCache.
