java - simple-spring-memcached升级到4.1.1导致WrappedCacheException

我最近将simple-spring-memcached从3.6.1版本升级到了4.1.1。但是，在此版本升级之后，每当我的代码尝试从缓存中获取值时，我都会收到WrappedCacheException。我在下面共享我的代码段：

@Transactional
@Cacheable(value = CACHE_NAME, key = "#id")
@Override
public TicketModel validate(final String id) {
    TicketEntity ticketEntity = ticketEntityRepository.findOne(id);
    if (ticketEntity == null) {
        System.out.println("Ticket not found")
    }
    return something;
}

我的cacheManager bean看起来像：

@Bean
public CacheManager cacheManager() throws Exception {
    List<SSMCache> cacheList = new ArrayList<>();

    CacheFactory cacheFactory;
    if (ELASTIC_CACHE_FACTORY.equals(cacheBean)) {
        cacheFactory = elastiCacheFactory();
    } else {
        cacheFactory = memCacheFactory();
    }

    Cache cache = cacheFactory.getObject();

    SSMCache aamCache = new SSMCache(cache, cacheTimeout, true);
    cacheList.add(aamCache);

    SSMCacheManager cacheManager = new SSMCacheManager();
    cacheManager.setCaches(cacheList);
    cacheManager.afterPropertiesSet();
    return cacheManager;
}

我得到的确切异常如下所示：

每当调用findOne（id）方法时，我都会收到WrappedCacheException，并且代码将失败。请帮忙。

最佳答案

在4.0.0之前，从底层缓存/客户端层抛出的异常（例如IOException等）被SsmCache对象吞噬。在4.0.0之后，默认情况下，这些将被抛出给调用者。通过将SsmCache bean上的“ muteExceptions”标志设置为true，可以恢复到先前的行为。
