在cache2k中使用@CacheResult注释的正确方式是什么

import org.cache2k.Cache;
import org.cache2k.Cache2kBuilder;
import org.cache2k.annotation.CacheResult;

public class CacheExample {

    private static Cache<String, String> cache;

    public static void main(String[] args) {
        cache = Cache2kBuilder.of(String.class, String.class)
                .eternal(true)
                .build();

        String result = getResultFromCache("key");
        System.out.println(result);
    }

    @CacheResult
    public static String getResultFromCache(String key) {
        // 从缓存中获取结果
        String cachedResult = cache.get(key);
        if (cachedResult != null) {
            return cachedResult;
        }

        // 如果缓存中不存在结果，则进行计算
        String result = computeResult(key);

        // 将计算结果放入缓存
        cache.put(key, result);

        return result;
    }

    public static String computeResult(String key) {
        // 计算逻辑
        return "Result for " + key;
    }
}
