非法状态异常:找不到持久资源的服务:磁盘 [ehCache 3]

Question

我想在应用程序重新启动后使缓存可用，并在配置中添加了以下行：

<disk unit="MB">100</disk>

之后，当我启动应用程序时，我有以下堆栈跟踪：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'cacheManager' defined in class path resource [my/pack/EhcacheConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.cache.CacheManager]: Factory method 'cacheManager' threw exception; nested exception is org.ehcache.StateTransitionException: Cache 'pow_cache' creation in EhcacheManager failed.

弹簧配置：

@Configuration
@EnableCaching
public class EhcacheConfig {
@Bean
public CacheManager cacheManager() throws URISyntaxException {
JCacheCacheManager jCacheCacheManager = new JCacheCacheManager(Caching.getCachingProvider().getCacheManager(
getClass().getResource("/ehcache.xml").toURI(),
getClass().getClassLoader()

javax.cache.CacheManager cacheManager = jCacheCacheManager.getCacheManager();
Cache<Object, Object> powCache = cacheManager.getCache("pow_cache");
return jCacheCacheManager;
}
}

春季启动版本2.1.6.RELEASEEHCACHE 版本3.6.3

我做错了什么？如何纠正？

附言

我想我需要提到磁盘上缓存的文件位置，但我不知道在哪里。

Answer 1

我已经添加了

<persistence directory="spring-boot-ehcache/cache" />

在<cache>标签和堆栈跟踪消失之前
