私はspringbootアプリケーションにキャッシュを追加しようとしていますが、起動時にorg.ehcache.jsr107.MultiCacheException例外がスローされる問題が発生しています。SpringbootとEhcache - MultiCacheException
私は（すべてはMavenのPOMファイルによってロードされた）次を使用しています：
@SpringBootApplication
@EnableCaching
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
私SpringBootApplicationは、このようになります
@Component
public class CacheConfig implements JCacheManagerCustomizer{
@Override
public void customize(javax.cache.CacheManager cacheManager) {
cacheManager.createCache("item", new MutableConfiguration<>()
.setExpiryPolicyFactory(CreatedExpiryPolicy.factoryOf(new Duration(TimeUnit.MINUTES, 5)))
.setStoreByValue(false)
.setStatisticsEnabled(true));
}
}
そして、私のehcache.xmlファイルが含まれています：
私は、次のものが含まCacheConfigクラスを持っている
<config
xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
xmlns='http://www.ehcache.org/v3'
xmlns:jsr107='http://www.ehcache.org/v3/jsr107'>
<service>
<jsr107:defaults>
<jsr107:cache name="item" template="heap-cache"/>
</jsr107:defaults>
</service>
<cache-template name="heap-cache">
<listeners>
<listener>
<class>org.terracotta.ehcache.EventLogger</class>
<event-firing-mode>ASYNCHRONOUS</event-firing-mode>
<event-ordering-mode>UNORDERED</event-ordering-mode>
<events-to-fire-on>CREATED</events-to-fire-on>
<events-to-fire-on>UPDATED</events-to-fire-on>
<events-to-fire-on>EXPIRED</events-to-fire-on>
<events-to-fire-on>REMOVED</events-to-fire-on>
<events-to-fire-on>EVICTED</events-to-fire-on>
</listener>
</listeners>
<resources>
<heap unit="entries">2000</heap>
<offheap unit="MB">100</offheap>
</resources>
</cache-template>
</config>
テスト項目サービスが含まれています
@Service
public class ItemService {
@CacheResult(cacheName = "item")
public String getItem(int itemNumber) {
switch (itemNumber) {
case 1:
return "Item 1";
case 2:
return "Item 2";
default:
return "No Item";
}
}
}
そして最後に、application.propertiesが含まれています
：私は、アプリケーションを実行するとspring.cache.jcache.config=classpath:ehcache.xml
を、私はで終わる次の例外を取得します

私はこのサイトで見つかったものをかなり複製しました： http://www.ehcache.org/blog/2016/05/18/ehcache3_jsr107_spring.html
洞察力は非常に高く評価されます。
ありがとうございました。
'@ CacheResult'で注釈を付けたサービスはどのように見えますか？質問に追加してください。 –
さて、テストサービスの外観を追加しました。 – Brad
