Regenerate Redis cache's access keys. This operation requires write permission to the cache resource.
- Mar 20, 2018 Spring Cache is nothing but a store of key-value pairs, where values are the ones returned from @Cacheable methods, whereas, for keys there has to be some strategy to generate them. By default Spring uses a simple key generation based on the following algorithm: If @Cacheable method has no arguments then SimpleKey.EMPTY is used as key.
- The Spring Data Redis project applies core Spring concepts to the development of solutions by using a key-value style data store. We provide a “template” as a high-level abstraction for sending and receiving messages.

Sep 15, 2015 We have earlier written few interesting articles on caching in spring and another good article on @Cacheable and @CacheEvict annotations for caching in spring. This is another comprehensive tutorial for spring caching using Spring 4.Spring caching is available since 3.1, but spring 4.1 has added lot of cool features with the existing spring caching framework. Org.springframework.data.redis.cache.RedisCacheConfiguration public class RedisCacheConfiguration extends Object Immutable RedisCacheConfiguration helps customizing RedisCache behaviour such as caching null values, cache key prefixes and binary serialization.

Introduction to spring cache
In spring 3.1, multi cache support is introduced, which is defined in the spring context packageorg.springframework.cache.Cacheandorg.springframework.cache.CacheManagerTwo interfaces to unify different caching technologies. Cache interface contains common operations of cache: add, delete, read, etc. CacheManager is an abstract interface for spring’s various caches.
The common cachemanagers supported by spring are as follows:
| CacheManager | describe |
|---|---|
| SimpleCacheManager | Using a simple collection to store the cache |
| ConcurrentMapCacheManager | Using java.util.concurrenthashmap to implement caching |
| NoOpCacheManager | Test only, no actual storage cache |
| EhCacheCacheManger | Use ehcache as the caching technology. Ehcache is a pure Java in-process cache framework, which is fast and capable. It is the default cache provider in Hibernate and the most widely used cache in Java field |
| JCacheCacheManager | Support the implementation of jcache (jsr-107) standard as caching technology |
| CaffeineCacheManager | Caffeine is used as caching technology. Used to replace guava caching technology. |
| RedisCacheManager | Using redis as caching technology |
| HazelcastCacheManager | Using hazelcast as caching technology |
| CompositeCacheManager | For combining cachemanagers, you can poll multiple cachemanagers to get the corresponding cache |
Spring cache provides @ cacheable, @ cacheput, @ cacheevict, @ caching and other annotations, which are used on methods. Through annotation cache, we can apply the cache logic transparently to our business code like transaction, and only need less code.
Core idea: when we call a method, we will store the parameter and return result of the method as the most key value pair in the cache. When we call the method with the same parameter next time, we will not execute it again, but directly get the result from the cache and return it.
Cache annotation

Enable the cache function, which is usually placed on the startup class.

When we need to cache more and more places, you can use @ cacheconfig (cachenames = {“cachename”}) annotation to uniformly specify the value of value in class. At this time, you can omit value. If you still write value in your method, the value of the method will still prevail.

Cache the returned results according to the method. In the next request, if the cache exists, directly read the cache data and return. If the cache does not exist, execute the method and store the returned results in the cache.Generally used in query methods。
View the source code. The attribute values are as follows:
| Property / method name | explain |
|---|---|
| value | Cache name, required, which specifies the namespace where your cache is stored |
| cacheNames | It’s about the same as value. Just choose one |
| key | Optional attribute. You can use the spiel tag to customize the cached key |
| keyGenerator | Key generator. Use one of the two key / keygenerators |
| cacheManager | Specify cache manager |
| cacheResolver | Specify get parser |
| condition | Cache if conditions are met |
| unless | Do not cache if conditions are met |
| sync | Whether to use asynchronous mode, default to false |

The method using this annotation flag is executed every time and the result is stored in the specified cache. Other methods can read the cached data directly from the response cache without querying the database.Generally used in new methods。

| condition | Cache if conditions are met |
| allEntries | Whether to clear all caches is false by default. If specified as true, all caches will be cleared immediately after the method call |
| beforeInvocation | Whether to clear before method execution. The default value is false. If specified as true, the cache is emptied before method execution |

This annotation can implement multiple annotations on the same method at the same time. You can see from its source code:
Spring cache usage
1. Build project and add dependency
2. Application.properties configuration file
3. entity class
4. Data layer Dao and mapper.xml
5. Business code layer interface service and implementation class serviceimpl
6. Test controller
7. Start the cache function
8. Database and test data
The database and test data are still the same as before.
9. test
Write unit tests, or by accessinghttp://127.0.0.1:8080/user/Add the corresponding path and parameters.
