java - ClassNotFoundException : org. springframework.cache.Cache$ValueRetrievalException 异常

Question

我正在使用 ehcache.xml 在 spring 中学习缓存，并在运行我的代码时遇到了这个异常。

    org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.cache.interceptor.CacheInterceptor#0': Cannot resolve reference to bean 'cacheManager' while setting bean property 'cacheManager'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'cacheManager' defined in ServletContext resource [/WEB-INF/springworld-servlet.xml]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: org/springframework/cache/Cache$ValueRetrievalException

下面是我的缓存机制的springworld-servlet.xml

    <cache:annotation-driven />

     <bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager" p:cache-manager-ref="ehcache"/>
<bean id="ehcache" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"
  p:config-location="/WEB-INF/ehcache.xml"/>

下面是我的ehcache.xml配置

    <?xml version="1.0" encoding="UTF-8"?>
    <ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="ehcache.xsd" 
updateCheck="true"
monitoring="autodetect" 
dynamicConfig="true">

    <diskStore path="java.io.tmpdir"/>
    <cache name="addresses"
   maxElementsInMemory="100"
   eternal="false"
   timeToIdleSeconds="120"
   timeToLiveSeconds="120"
   overflowToDisk="true"
   maxElementsOnDisk="10000000"
   diskPersistent="false"
   diskExpiryThreadIntervalSeconds="120"
   memoryStoreEvictionPolicy="LRU"/>

    </ehcache>

我在谷歌上搜索了它，但没有找到任何关于我从哪里得到包含这个类的 jar 的解决方案。 这个类到底有什么用，谁需要它。

这个类是在 Spring 4.3 中引入的。参见 https://github.com/spring-projects/spring-framework/blob/master/spring-context/src/main/java/org/springframework/cache/Cache.java#L164
