Question

我还是刚接触到春天，我正在尝试正确设置ehcache spring注释。我正在使用Spring 3.2.3 ehCache 2.4和ehcache-spring-annotations-1.2。

当我尝试访问对cacheManager的引用时，它始终为null。所有jar都在构建路径上，ehcache.xml在类路径中，没有xml错误。我也试过在组件扫描中包含类并使用@Resource而不是Autowired。我被卡住了！

申请背景：

 <context:component-scan      base-package="org.springframework.cache.ehcache.EhCacheManagerFactoryBean,com    .defaultPackage,net.sf.ehcache.CacheManager" />

<!-- ehCache Annotation settings -->
<ehcache:annotation-driven cache-manager="ehCacheManager" />
<bean id="ehCacheManager"   class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
    <property name="configLocation" value="classpath:ehcache.xml" />
    <property name="shared" value="true"/>
</bean>

包装

@Component
public final class MyCache implements Serializable {

@Autowired
private CacheManager ehCacheManager;

private getCacheManager() {
    return ehCacheManger; // this is always null
}...}

您似乎正在尝试使用EhCacheManagerFactoryBean作为缓存管理器。

查看Spring caching documentation，您需要将另一个bean声明为从工厂创建的CacheManager。

使用ehcache spring注释为cacheManager自动装配spring bean null
