EhCache 未找到序列化程序

Question

我正在通过以下方式初始化我的缓存：

CacheManager cacheManager;

cacheManager = CacheManagerBuilder.newCacheManagerBuilder().build();
cacheManager.init();

Cache<String, SmsMessageDto> myCache = cacheManager.createCache("myCache", CacheConfigurationBuilder.newCacheConfigurationBuilder(String.class, SmsMessageDto.class)
    .withExpiry(Expirations.timeToLiveExpiration(new Duration(cacheDuration, TimeUnit.MINUTES)))
    .build());
    

这给了我以下警告：

org.ehcache.core.EhcacheManager - Could not create serializers for myCache

如何说服 EhCache 使用我toString的com.example.dto.SmsMessageDto对象方法？

Answer 1

鉴于您没有使用堆外层或磁盘层，因此不需要序列化器。

现在我看到你正在使用版本3.0.0.rc1。我强烈建议此时不要使用 RC，而是使用最新的（此时）3.1.2。

我相信您遇到的是一个错误，此后很可能已经修复。
