问几个关于spymemcached的问题

[weixin_38050048]

使用net.spy.memcached.spring.MemcachedClientFactoryBean与Spring结合，MemcachedClient是在什么时候shutdown的？ 配置： <bean id="memcachedClient" class="net.spy.memcached.spring.MemcachedClientFactoryBean"> <property name="servers" value="1.2.3.4:11211 1.2.3.5:11211" /> <property name="protocol" value="BINARY" /> <property name="transcoder"> <bean class="net.spy.memcached.transcoders.SerializingTranscoder"> <property name="compressionThreshold" value="1024"/> </bean> </property> <property name="opTimeout" value="1000" /> <property name="timeoutExceptionThreshold" value="1998" /> <property name="hashAlg" value="KETAMA_HASH" /> <property name="locatorType" value="CONSISTENT" /> <property name="failureMode" value="Redistribute" /> <property name="useNagleAlgorithm" value="false" /> <property name="authDescriptor"> <bean class="net.spy.memcached.auth.AuthDescriptor"> <constructor-arg index="0"> <value>PLAIN</value> </constructor-arg> <constructor-arg index="1"> <bean class="net.spy.memcached.auth.PlainCallbackHandler"> <constructor-arg index="0"> <value>bucketName</value> </constructor-arg> <constructor-arg index="1"> <value>bucketNamePwd</value> </constructor-arg> </bean> </constructor-arg> </bean> </property> </bean> Spring中配置的Bean是单例的吧，MemcachedClientFactoryBean每次都重新new一个MemcachedClient返回，但是这个MemcachedClient是啥时候关闭的呢？ 难道是每次自己调用完某个操作后手动去shutdown？ 比如： public void set(String key,Object value){ MemcachedClient mc = (MemcachedClient)memcachedClient.getObject(); OperationFuture<Boolean> future = mc.set("Hello", 0, "OCS"); mc.shutdown(); } 这样会有神马问题吗？
