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:

我如何说服 EhCache 使用我的 toString com.example.dto.SmsMessageDto的方法目的？

Answer 1

简而言之，这是不可能的。你必须执行 Serializable您类(class)中的界面 SmsMessageDto .它将为您的 Serializable 类和 Exception 创建一个序列化程序。不会再次显示。此答案基于以下链接 http://www.ehcache.org/documentation/3.1/serializers-copiers.html部分捆绑的实现。
从文档:

By default, cache managers are pre-configured with specially optimizedSerializer that can handle the following types, in the followingorder:

java.io.Serializable

java.lang.Long

java.lang.Integer

java.lang.Float

java.lang.Double

java.lang.Character

java.lang.String

byte[]
