1. 自動配置類：CacheAutoConfiguration
2. 快取的配置類：
org.springframework.boot.autoconfigure.cache.GenericCacheConfiguration
org.springframework.boot.autoconfigure.cache.JCacheCacheConfiguration
org.springframework.boot.autoconfigure.cache.EhCacheCacheConfiguration
org.springframework.boot.autoconfigure.cache.HazelcastCacheConfiguration
org.springframework.boot.autoconfigure.cache.InfinispanCacheConfiguration
org.springframework.boot.autoconfigure.cache.CouchbaseCacheConfiguration
org.springframework.boot.autoconfigure.cache.RedisCacheConfiguration
org.springframework.boot.autoconfigure.cache.CaffeineCacheConfiguration
org.springframework.boot.autoconfigure.cache.SimpleCacheConfiguration
org.springframework.boot.autoconfigure.cache.NoOpCacheConfiguration
3. 默認生效的是SimpleCacheConfiguration
@Configuration(proxyBeanMethods = false) @ConditionalOnMissingBean(CacheManager.class) @Conditional(CacheCondition.class) class SimpleCacheConfiguration { @Bean ConcurrentMapCacheManager cacheManager(CacheProperties cacheProperties, CacheManagerCustomizers cacheManagerCustomizers) { ConcurrentMapCacheManager cacheManager = new ConcurrentMapCacheManager(); List<String> cacheNames = cacheProperties.getCacheNames(); if (!cacheNames.isEmpty()) { cacheManager.setCacheNames(cacheNames); } return cacheManagerCustomizers.customize(cacheManager); } }
4. 給容器中注冊了一個CacheManager：ConcurrentMapCacheManager
5. 可以獲取和創建ConcurrentMapCache型別的快取組件：將資料保存在ConcurrentMap中
