我不确定是什么导致了错误，我得到了一个成功的“maven clean/package/install”。但是，在执行“grails compile”时，我从 cache-ehcache 插件中收到了一个不推荐使用的警告（如下所示），我假设这可能是我收到此错误的原因，但不确定如何解决它。
Note: C:\Users\kgeoffroy\Documents\dev\soc-track-upgrade\SOCScheduleServiceWEB\target\plugins\cache-ehcache-1.0.5\src\java\grails\plugin\cache\ehcache\G
railsEhCacheManagerFactoryBean.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
我会尝试看看是否有该插件的更高版本。到目前为止，我大部分时间都被限制在一个 nexus 镜像存储库中，所以我无法找到更高版本来测试。

根据一个未解决的问题https://github.com/grails-plugins/grails-cache-ehcache/issues/41，这可能是一个错误，但没有提供解决方案或解决方法。
我正在从 Grails 2.2.0 升级到 2.4.5，我更新了 Datasource.groovy 以指出正确的 hibernate4 ehCache 类：
hibernate {
cache.use_second_level_cache = true
cache.use_query_cache = true
// cache.provider_class = 'net.sf.ehcache.hibernate.EhCacheProvider' //Outdated class
// http://grails-plugins.github.io/grails-cache-ehcache/guide/usage.html
cache.region.factory_class = 'grails.plugin.cache.ehcache.hibernate.BeanEhcacheRegionFactory' // For Hibernate before 4.0
cache.region.factory_class = 'grails.plugin.cache.ehcache.hibernate.BeanEhcacheRegionFactory4' // For Hibernate before 4.0 and higher
}
配置.groovy：
/*https://github.com/grails/grails-core/releases/tag/v2.4.5
* ehcache 2.9.0 is more strict about the configuration.
* ehcache is used in the spring-security-core plugin for caching users.
* There is a problem reported as GRAILS-12120.
* As a workaround to the "net.sf.ehcache.CacheException:
* Another unnamed CacheManager already exists in the same VM.
* " error you can add this config to Config.groovy:*/
beans {
cacheManager {
shared = true
}
}
我试图了解这MalformedObjectNameException: Invalid character ':' in value part of property是从哪里来的，因为该项目没有配置任何 ehcache，它只是使用了缓存插件中的一些类。下面是一个示例缓存服务实现：
