Grails3上的ehcache插件可能存在问题

配置为：

编译“org.grails.plugins:cache-ehcache:2.0.0.BUILD-SNAPSHOT”

在使用grails run app或grails prod run app测试应用程序时，此问题似乎并不明显

当我发起一场战争并将其移植到tomcat时，在启动应用程序时出现了这个错误，应用程序无法启动。我删除了大量与缓存相关的引用，但仍然存在相同的问题。我发现在禁用上面的插件后，它启动了

这是堆栈跟踪（可能与多个dsn有关），我尝试跟踪问题链接，但jira链接已关闭：

我也遇到了同样的问题，通过在build.gradle中进行以下更改，我成功地解决了这个问题：

compile ("org.grails.plugins:cache-ehcache:3.0.0.BUILD-SNAPSHOT") {
  exclude group:'net.sf.ehcache'
}

compile "net.sf.ehcache:ehcache:2.4.3"

看来缓存ehcache:3.0.0.BUILD-SNAPSHOT使用的ehcache（2.10.2）比grails提供的hibernate缓存（2.4.3内核）使用的更新。当两者都包含在war中时，ehcache在tomcat中启动失败

---

使用Grails3.0.17进行测试。

这似乎也适用于Grails3.2.3。但是，Grails3.2.3中的hibernate缓存的Grails附带的ehcache版本是ehcache 2.10.1。因此，将ehcache降级到2.4.3并不安全。
