Springboot-redis Cache

Redis Cache Usage

1. Introduction of dependencies (may have been introduced): Spring-boot-starter-cache

2. Configure the Spring:redis:host/port/password in the Application.yml configuration file to connect to the Redis library

3. Add annotations to the main launcher: @EnableChaching

4. Add annotations to the method that requires caching:@Cacheable (cachename= "". key= "")

5. The outermost object of the return page needs to be serialized: Implement Interface serializable

6. Use the Generateserialversionuid plugin to generate unique IDs for objects that need to be serialized (using shortcut keys)

Redis Cache Update

Method One: Add annotations to the method that needs to update the cache:@CachePut (cachename= "". key= "")

Note: Sometimes the returned data is not in JSON format but in view format, when serialization fails, and this method cannot be used

Method Two: Add a note to the method that needs to delete the cache:@CacheEvict (cachename= "". key= "")
