通过memcache集成的spring mvc中的这个错误是什么？

Question

我想使用simple-spring-memcached来缓存数据。所以为了我的目的使用这个https://code.google.com/p/simple-spring-memcached/wiki/Getting_Started。我在dispatcher-servlet.xml中添加了

  <aop:aspectj-autoproxy />
  <import resource="simplesm-context.xml" /> 
  <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="defaultCache"/>
                <!-- 5 minutes -->
                <constructor-arg name="expiration" index="1" value="0"/>
                <!-- @CacheEvict(..., "allEntries" = true) doesn't work -->
                <constructor-arg name="allowClear" index="2" value="false"/>
            </bean>
        </set>
    </property>

</bean>
<bean name="defaultCache" class="com.google.code.ssm.CacheFactory">
    <property name="cacheName" value="defaultCache"/>
    <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>

我还将simple-spring-memcached-3.5.0.jar和spymemcache.jar，spymemcache-provider.jar添加到lib文件夹中。但是当我运行我的项目时，发生了以下异常：

 Cannot find class **[net.nelz.simplesm.config.MemcachedClientFactory]** for bean with name 'memcachedClientFactory' defined in ServletContext resource [/WEB-INF/simplesm-context.xml]; nested exception is java.lang.ClassNotFoundException: net.nelz.simplesm.config.MemcachedClientFactory

Answer 1

你必须为这个类添加lib。

Answer 2

看起来您的类路径上也有一个旧版本的Simple Spring Memcached。net.nelz.simplesm.config.MemcachedClientFactory类在3.x中不再可用。检查类路径并删除早于3.5.0的所有简单Spring Memcached工件。
