@Configuration
@EnableCaching
public class CacheConfig {

    @Bean
    public CacheManager cacheManager() {
        SimpleCacheManager cacheManager = new SimpleCacheManager();
        List<Cache> caches = new ArrayList<>();
        caches.add(ehCacheCache());
        cacheManager.setCaches(caches);
        return cacheManager;
    }

    @Bean
    public Cache ehCacheCache() {
        EhCacheFactoryBean factoryBean = new EhCacheFactoryBean();
        factoryBean.setCacheName("myCache");
        factoryBean.setTimeToLive(60); // 设置TTL超时时间为60秒
        factoryBean.afterPropertiesSet();
        return new EhCacheCache(factoryBean.getObject());
    }
}

@Service
public class MyService {

    @Cacheable(value = "myCache")
    public String getData() {
        // 从数据库或其他外部系统获取数据的逻辑
        return "data";
    }
}
