Question

我的项目有hibernate l2缓存，并使用ehcache来管理这个配置

hibernate.cache.region.factory_class：org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory

迁移到Spring boot 2后，我得到了这个异常

Caused by: java.lang.annotation.IncompleteAnnotationException: org.terracotta.statistics.Statistic missing element type

在问了一些问题后，我发现ehcache都是2x和3x 有我的项目和异常原因是，但当排除2x。看到春天需要启动2 x。如何解决这个问题

Answer 1

通过替换：

解决了这个问题

    <dependency>
        <groupId>org.ehcache</groupId>
        <artifactId>ehcache</artifactId>
    </dependency>

以下内容：

   <dependency>
        <groupId>net.sf.ehcache</groupId>
        <artifactId>ehcache</artifactId>
    </dependency>

AS OF SPRING BOOT 2.0.2

删除：

spring.jpa.properties.hibernate.cache.region.factory_class: org.hibernate.cache.ehcache.EhCacheRegionFactory

删除：

    <dependency>
        <groupId>net.sf.ehcache</groupId>
        <artifactId>ehcache</artifactId>
    </dependency>
