spring-cache

问题 We're using Spring Boot 2 and Spring Actuator. When creating a cache like the following: @Bean public CaffeineCache someCache() { return new CaffeineCache("my-cache", Caffeine.newBuilder() .maximumSize(1000) .expireAfterWrite(10, TimeUnit.SECONDS) .build()); } it is registered into Spring Actuator and can be accessed and handle via endpoints: ❯ http GET localhost:8080/actuator/caches { "cacheManagers": { "cacheManager": { "caches": { "my-cache": { "target": "com.github.benmanes.caffeine.cache

问题 My question relates to Spring's AspectJ mode and especially how to enable it for: Transaction management Caching 1) I noticed that in order to enable the AspectJ mode for transaction management, I only had to do the following: @Configuration @EnableTransactionManagement(mode = AdviceMode.ASPECTJ) 2) Whereas in order to use AspectJ mode for caching it seems one has to: -Put the following jar into Tomcat's lib directory: org.springframework:spring-instrument-tomcat -Add the following line in

问题 I'm using Caffeine Cache library for Spring Cache. Is there a way to get all the cached keys? My current application works on a near-realtime data, with the flow as : In the Cache Updater Thread (which runs at a fixed interval, irrespective of the user request), I need to get all the keys currently in the Cache, fetch their latest data from Db & then use @CachePut to update the cache. 回答1: Yo can inject CacheManager and obtain native cache from it. @AllArgsConstructor class Test { private

问题 I'm working on a Spring Boot application where I have a scenario to put @CachePut and @CacheEvict on the same method. I tried the scenario with this code given below : @CachePut(value="myValue",key="#entity.getId(),#entity.getOrgId()", cacheManager="no-expire-caching") @CacheEvict(value="myValue", key="#entity.getId(),#entity.getOrgId()", cacheManager="no-expire-caching", condition="#entity.isDeleted() == true") public MyEntity save(boolean flag, MyEntity entity){ if (flag==true){ entity
