Hibernate Infinispan 2LC：同一缓存区域中的查询缓存和实体缓存
Hibernate Infinispan 2LC : query cache and entity cache in same cache region
使用JBoss 缓存，可以毫无问题地将entity 缓存和query 缓存存储在同一缓存区域中。但是一旦迁移到wildfly 10（infinispan为2LC），似乎有问题。
我已经为下面的实体提供了缓存区域。
@Entity
@Cacheable
@Cache(usage=CacheConcurrencyStrategy.READ_ONLY,
region="regionA")
public class EntityXYZ{
查询缓存为
entManager.createQuery(
"....")
.setHint("org.hibernate.cacheable", true)
.setHint("org.hibernate.cacheRegion", "regionA").getResultList();
重要的是要注意上面的 query 还包含本身声明为 cacheable 的 entities 并且具有与 regionA 相同的缓存区域。
现在执行，出现这个错误。我怀疑这是由于冲突，因为它们存储在同一区域并且它试图获取 returns 另一个对象的对象 ID。但是有人可以投光吗？真的是这样吗？并详细解释错误？
但在 JBoss 5 中的 JBoss 缓存中同样有效。 infinispan 处理方式不同吗？或者这是 Hibernate 问题？

更新：
entitymanager 尝试加载 2 的不同调用，例如 classes（在同一共享缓存 2LC 区域中）具有 @id 和 int。正如 Flavius 指出的那样，id=4 似乎在 2 classes 之间很常见。
将以下配置添加到 persistence.xml 时，出现启动错误。
persistence.xml
<property name="hibernate.cache.keys_factory" value="default" />

查询缓存是字符串索引的，实体缓存是使用原始 ID 索引的（与 EntityXYZ 中标有 @Id 的 field/method 相同的对象）所以我想知道冲突是如何发生的发生在 id=4.
无论如何，为实体和查询使用相同的区域（缓存）不是一个好主意——实体有时需要更复杂的处理来实现数据库式隔离。对于 Hibernate 6，这样的组合可能根本不可能。在您 运行 在许多线程中进行压力测试之前，您可能不会遇到问题，顺序调用通常可以正常工作。
如果你坚持要将它们存储在同一个缓存中，你可以尝试设置hibernate.cache.keys_factory=default（我希望你的WF版本已经包含这个设置，新版本应该已经默认了）
