"client not initialized" error when using SSMCache with AWS elasticache autodiscovery

Question

I am using Spring cache with AWS elasticache provider. I get this warning:

WARN c.g.code.ssm.spring.SSMCache - An error has occurred for cache defaultCache and key 

java.lang.IllegalStateException: Client is not initialized

I am using the same memcache without spring cache and it works fine. I get this error only when I use spring cache.

I have verified that the security groups has the Inbound port specified and I am running my code on EC2.

UPDATE 1:

adding my config -

<bean name="cacheManager" class="com.google.code.ssm.spring.SSMCacheManager">
    <property name="caches">
            <set>
                    <bean class="com.google.code.ssm.spring.SSMCache">
                            <constructor-arg name="cache" index="0" ref="defaultMemcachedClient" />
                            <!-- 5 minutes -->
                            <constructor-arg name="expiration" index="1" value="3600" />
                            <!-- @CacheEvict(..., "allEntries" = true) won't work because allowClear is false, 
                            so we won't flush accidentally all entries from memcached instance -->
                            <constructor-arg name="allowClear" index="2" value="false" />

    </bean>

Answer 1

Show your configuration and usage.

It seams that you haven't defined defaultCache or used Cacheable without 'value' param set.
