我想设置 spring 方法缓存和由 ehcache 备份的休眠 2 级缓存:

在 spring-context.xml 中已经配置了 hibernate 2 级缓存:

<!-- hibernate level 2 cache configuration -->
<bean id="hibernateCacheManager"
    class="net.sf.ehcache.CacheManager" 
    factory-bean="hibernateCacheManagerFactory"
    factory-method="createCacheManager"
    destroy-method="shutdown" />
<bean id="hibernateCacheManagerFactory" 
    class="com.project.CustomEhCacheManagerFactoryBean" />

缓存配置是从自定义 xml 文件中读取的,以便我们可以自定义需求并轻松测试缓存的实体:

public class CustomEhCacheManagerFactoryBean {
    public CacheManager createCacheManager() {
        final Configuration configuration = new Configuration();            
        // read the xml configuration
        //for each node in xml
            final CacheConfiguration cache = new CacheConfiguration();
            // set the properties
            configuration.addCache(cache);
        // end for
        cacheManager = CacheManager.create(configuration);
    }
}

现在我想这次使用注释添加另一个缓存管理器的spring方法缓存。我在 spring-context.xml 中添加了以下内容:

<!-- suport method caching through annotation -->
<cache:annotation-driven />
<!-- spring method cache configuration -->
<bean id="cacheManager" 
    class="org.springframework.cache.ehcache.EhCacheCacheManager">
        <property name="cacheManager" ref="springEhcache"/>
</bean>
<bean id="springEhcache" 
    class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
        <property name="cacheManagerName" value="method-cache" />
</bean>

然后我得到以下异常:

Caused by: 
java.lang.IllegalArgumentException: loadCaches must not return an empty Collection
at org.springframework.util.Assert.notEmpty(Assert.java:268)
at org.springframework.cache.support.AbstractCacheManager.afterPropertiesSet(AbstractCacheManager.java:49)
at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.invokeInitMethods(AbstractAutowireCapableBeanFactory.java:1514)

Q1:不应该通过注释自动配置缓存吗?我错过了什么?

Q2: 是否可以给这个bean idspringCacheManager而不是cacheManager?目前我得到异常:没有找到bean'cacheManager'

谢谢
