ssm bean 配置

    <import resource="classpath:simplesm-context.xml" />
    <aop:aspectj-autoproxy />

    <bean name="defaultMemcachedClient" class="com.google.code.ssm.CacheFactory">
        <property name="cacheClientFactory">
            <bean name="cacheClientFactory" class="com.google.code.ssm.providers.xmemcached.MemcacheClientFactoryImpl" />
        </property>
        <property name="addressProvider">
            <bean class="com.google.code.ssm.config.DefaultAddressProvider">
                <property name="address" value="127.0.0.1:11211" />
            </bean>
        </property>
        <property name="configuration">
            <bean class="com.google.code.ssm.providers.CacheConfiguration">
                <property name="consistentHashing" value="true" />
            </bean>
        </property>
    </bean>

调用方法配置

@Service
public class TagService {

    @ReadThroughSingleCache(namespace = "test", expiration = 30000)
    public Tag getOrder(@ParameterValueKeyProvider String orderNum) {
        System.out.println("缓存没有命中");
        return new Tag();
    }
}

每次都给这个方法传字符串“1”，但是每次访问在terminal里没有看到新建的key/value，
每次打印缓存没有命中，但是console不报任何错误，也没法debug，求助大神
