如果我使用cacheBuilder，如何为具体的缓存定制expireAfterWrite？

import com.google.common.cache.CacheBuilder;
import com.google.common.cache.CacheLoader;
import com.google.common.cache.LoadingCache;
import java.util.concurrent.TimeUnit;

public class ExampleCache {
    private LoadingCache<String, String> cache;

    public ExampleCache() {
        cache = CacheBuilder.newBuilder()
                .expireAfterWrite(10, TimeUnit.MINUTES) // 设置缓存项在写入后的10分钟内过期
                .build(new CacheLoader<String, String>() {
                    @Override
                    public String load(String key) throws Exception {
                        // 缓存未命中时的加载逻辑
                        return loadDataFromSource(key);
                    }
                });
    }

    public String get(String key) {
        return cache.getUnchecked(key);
    }

    private String loadDataFromSource(String key) {
        // 从数据源加载数据的逻辑
        return "Data for key " + key;
    }
}
