java - 使用 ehcache 时出错

Question

我刚开始使用 ehcache，我使用下面的设置。当我设置 ehcache 3 时，我的项目编译良好，但是当我在端点上发送查询时，出现错误:

           maxEntriesLocalHeap="5000" eternal="true">
        <persistence strategy="localTempSwap" />
    </cache>
</ehcache> 

在主要的 spring boot 应用程序中，我使用 @EnableCaching。和我在实体上使用的注释:

@SuppressWarnings("serial")
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE, region="billCache")
@Cacheable

您收到一个抽象方法异常，因为您需要在 hibernate 和 ehcache 之间连接提供程序。

执行此操作的方法在 documentation here 中.

简而言之，您的 hibernate 属性配置部分还需要包括:

         setProperty("hibernate.cache.provider_class", "org.hibernate.cache.EhCacheProvider");
