有没有一种干净利落的方法来改变Nimbus Jose JWT中的默认JWKSetCache TTL？

import com.nimbusds.jose.jwk.JWKSetCache;
import com.nimbusds.jose.jwk.source.RemoteJWKSet;

public class CustomJWKSetCache extends DefaultJWKSetCache {

    private static final long TTL = 3600 * 1000; // 设置缓存的生存时间为1小时

    @Override
    public RemoteJWKSet get(String uri) {
        CacheEntry entry = cache.get(uri);
        if (entry != null && !isExpired(entry)) {
            return entry.getJWKSet();
        } else {
            // 缓存过期或不存在，重新获取JWKSet并缓存
            RemoteJWKSet jwkSet = super.get(uri);
            cache.put(uri, new CacheEntry(jwkSet));
            return jwkSet;
        }
    }

    @Override
    public void put(String uri, RemoteJWKSet jwkSet) {
        cache.put(uri, new CacheEntry(jwkSet));
    }

    private boolean isExpired(CacheEntry entry) {
        long currentTime = System.currentTimeMillis();
        return (currentTime - entry.getCreationTime()) > TTL;
    }

    private static class CacheEntry {
        private final RemoteJWKSet jwkSet;
        private final long creationTime;

        public CacheEntry(RemoteJWKSet jwkSet) {
            this.jwkSet = jwkSet;
            this.creationTime = System.currentTimeMillis();
        }

        public RemoteJWKSet getJWKSet() {
            return jwkSet;
        }

        public long getCreationTime() {
            return creationTime;
        }
    }
}

import com.nimbusds.jose.jwk.source.JWKSource;
import com.nimbusds.jose.jwk.source.RemoteJWKSet;

JWKSource<RemoteJWKSet> jwkSource = new RemoteJWKSet<>(jwksURI, new CustomJWKSetCache());
