Expiry time @cacheable spring boot

I use life hacking like this

    @Configuration
    @EnableCaching
    @EnableScheduling
    public class CachingConfig {
        public static final String GAMES = "GAMES";
        @Bean
        public CacheManager cacheManager() {
            ConcurrentMapCacheManager cacheManager = new ConcurrentMapCacheManager(GAMES);

            return cacheManager;
        }

        @CacheEvict(allEntries = true, value = {GAMES})
        @Scheduled(fixedDelay = 10 * 60 * 1000 ,  initialDelay = 500)
        public void reportCacheEvict() {
            System.out.println("Flush Cache " + dateFormat.format(new Date()));
        }
    }

Note that this answer uses ehcache, which is one of supported Spring Boot cache managers, and arguably one of the most popular.

First you need to add to pom.xml:

<!-- Spring Framework Caching Support -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-cache</artifactId>
</dependency>
<dependency>
    <groupId>net.sf.ehcache</groupId>
    <artifactId>ehcache</artifactId>
</dependency>

In src/main/resources/ehcache.xml:

<?xml version="1.0" encoding="UTF-8"?>
<ehcache>
    <defaultCache eternal="true" maxElementsInMemory="100" overflowToDisk="false" />
    <cache name="forecast" 
           maxElementsInMemory="1000" 
           timeToIdleSeconds="120"
           timeToLiveSeconds="120"
           overflowToDisk="false"
           memoryStoreEvictionPolicy="LRU" />
</ehcache>

From the reference documentation

Directly through your cache provider. The cache abstraction is… well, an abstraction not a cache implementation. The solution you are using might support various data policies and different topologies which other solutions do not (take for example the JDK ConcurrentHashMap) - exposing that in the cache abstraction would be useless simply because there would no backing support. Such functionality should be controlled directly through the backing cache, when configuring it or through its native API.

You cannot specify expiry time with @cacheable notation, since @cacheable does not provide any such configurable option.

However different caching vendors providing spring caching have provided this feature through their own configurations. For example NCache / TayzGrid allows you to create different cache regions with configurable expiration time.

If you have implemented your own cache, you will need to define a way to specify expiration in you cache provider and will also need to incorporate expiration logic in your solution.
