我的项目有休眠 l2 缓存并使用 ehcache 通过此配置进行管理

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

问了一些问题后，我发现 ehcache 2x 和 3 x 在我的项目中都有，异常原因是这样，但是当排除 2x 时，请参阅 spring 需要启动 2 x。如何解决这个问题

通过替换解决了这个问题：

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

具有以下内容：

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

从 Spring Boot 2.0.2 开始

消除：

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

消除：

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

通过使用修复了问题，

<dependency>
    <groupId>org.ehcache</groupId>
    <artifactId>ehcache</artifactId>
    <version>3.0.0</version>
</dependency>
