Java 如何为JPA L2缓存配置WIldfly infinispan子系统？

我正在尝试在Wildfly 14上启用JPA二级缓存。即使我已经添加了配置缓存，也没有发生。日志显示实体正在被缓存，但在检索实体时似乎没有使用缓存

我使用Hibernate作为JPA提供程序，这些是我的配置

• wildfly中的standalon-ha.xml

  <cache-container name="hibernate">
      <transport lock-timeout="60000"/>
      <local-cache name="local-query">
          <object-memory size="10000"/>
          <expiration max-idle="100000"/>
      </local-cache>
      <invalidation-cache name="entity">
          <transaction mode="NON_XA"/>
          <object-memory size="10000"/>
          <expiration max-idle="100000"/>
      </invalidation-cache>
      <replicated-cache name="timestamps"/>
  </cache-container>
  

这是执行数据库查询时从Hibernate获得的输出。每次我看到数据库查询都在进行

我们为WildFly提供了Infinispan Hibernate缓存教程。我强烈建议你遵循这一点。它目前使用的是WildFly 15，但应该可以与WildFly 14配合使用

要知道的最重要的一点是，您不需要在persistence.xml中定义一半的属性。看

这本书和许多其他Infinispan简单教程都可以找到。特别是，我们有一些简单的教程，展示如何在独立或Spring应用程序中使用Infinispan Hibernate缓存。这些用例的配置可能略有不同

@Entity
@Cacheable
@Table(name = "table_name")
public class EntityName implements Serializable { // }
