Jetcache获取cache对象

Jetcache获取cache对象

@Component
public class JetcacheUtil implements ApplicationContextAware {

    private ApplicationContext applicationContext;

    private SpringConfigProvider springConfigProvider;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        this.applicationContext = applicationContext;
        this.springConfigProvider = applicationContext.getBean("springConfigProvider", SpringConfigProvider.class);
    }

    public void put(String name, Object key, Object value, int expire, TimeUnit unit) {
        Cache cache = getCache(name);
        cache.put(Lists.newArrayList(key), value, expire, unit);
    }

    private Cache getCache(String name) {
        SimpleCacheManager cacheManager = springConfigProvider.getCacheManager();
        return cacheManager.getCache(name);
    }
}

SpringConfigProvider是通过JetCacheAutoConfiguration获取

• 目的是获取SimpleCacheManager
