Springboot和Ehcache - MultiCacheException

标签： java spring-boot ehcache jsr107

我正在尝试将缓存添加到springboot应用程序中，并且我遇到了在启动期间抛出org.ehcache.jsr107.MultiCacheException异常的问题。

我使用以下内容（全部通过Maven pom文件加载）： Springboot 1.5.5，Ehcache 3.3.1，Javax cache 1.0.0

我的SpringBootApplication看起来像这样：

@SpringBootApplication
@EnableCaching
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

我有一个包含以下内容的CacheConfig类：

@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));
    }
}

我的ehcache.xml文件包含：

<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>

测试项目服务包含：

@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";

        }
    }
}

最后，application.properties包含：

spring.cache.jcache.config=classpath:ehcache.xml

当我运行应用程序时，我得到以下结尾的以下异常：

我不确定该去哪里，因为我几乎复制了在这个网站上发现的东西： http://www.ehcache.org/blog/2016/05/18/ehcache3_jsr107_spring.html

非常感谢任何见解。

感谢。

答案 0 :(得分：5)

事实证明，ehcache.xml文件中定义的org.terracotta.ehcache.EventLogger类只是一个示例记录器，用于上面博客文章中定义的测试程序。软件包名称让我相信它是ehcache发行版的一部分。

当我浏览代码时，我看到正在生成NoClassDefFoundError异常，并导致抛出MultiCacheException。堆栈跟踪中没有任何内容表明NoClassDefFoundError是真正的罪魁祸首。我创建了自己的EventLogger，现在一切正常。

感谢指点！
