2.キャッシュツール類CacheUtil

package cn.flyinke.sb;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cache.Cache;
import org.springframework.cache.CacheManager;
import org.springframework.stereotype.Component;
import javax.annotation.PostConstruct;
import static javafx.scene.input.KeyCode.T;

@Component
public class CacheUitl {

    @Autowired
    private CacheManager cacheManager;

    private static CacheManager cm;

    @PostConstruct
    public void init(){
        cm = cacheManager;
    }

    public static void put(String cacheName,String key,Object value){
        Cache cache = cm.getCache(cacheName);
        cache.put(key,value);
    }

    public static Object get(String cacheName,String key){
        Cache cache = cm.getCache(cacheName);
        if(cache == null){
            return null;
        }
        return cache.get(key).get();
    }

    public static  T get(String cacheName,String key,Class clazz) {
        Cache cache = cm.getCache(cacheName);
        return cache.get(key, clazz);
    }

    public static void evict(String cacheName,String key){
        Cache cache = cm.getCache(cacheName);
        cache.evict(key);
    }
}

import org.springframework.stereotype.Service;

@Service
public class IndexService {

    @Cacheable(cacheNames = "captchaCache",key = "#p")
    public double random(String p){
        return Math.random();
    }
}
