Comment implémenter la mise en cache et la gestion de la couche cache des données de formulaire en Java ?

import com.google.common.cache.Cache; import com.google.common.cache.CacheBuilder; public class FormCache { private static Cache cache = CacheBuilder.newBuilder() .maximumSize(1000) // 设置缓存的最大容量 .build(); public static void put(String key, FormData data) { cache.put(key, data); } public static FormData get(String key) { return cache.getIfPresent(key); } }

public class CacheLayerManager { private static Cache cache = CacheBuilder.newBuilder() .maximumSize(1000) .expireAfterWrite(30, TimeUnit.MINUTES) // 设置缓存的存活时间30分钟 .build(); static { // 定时清理缓存 ScheduledExecutorService executorService = Executors.newSingleThreadScheduledExecutor(); executorService.scheduleAtFixedRate(new Runnable() { @Override public void run() { cache.cleanUp(); } }, 0, 1, TimeUnit.HOURS); // 每小时清理一次缓存 } public static void put(String key, FormData data) { cache.put(key, data); } public static FormData get(String key) { return cache.getIfPresent(key); } }
