Answer 1

defaultCache 这个属性有没有setter方法啊 
即 需要定义public void setDefaultCache(Type defaultCache){
   this.defaultCache  = defaultCache ;
}

Answer 2

Caused by: java.lang.NoClassDefFoundError: com/danga/MemCached/MemCachedClient很明显了，你的classes/com/danga/MemCached/目录下有没有MemCachedClient.class

Answer 3

Answer 4

完整的配置文件呢。org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'cacheFactory' defined in file [E:\tomcat-6.0.18\Tomcat 6.0\webapps\wulindemo\WEB-INF\classes\spring\cache.xml]: Cannot resolve reference to bean 'memcache' while setting bean property 'defaultCache'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'memcache' defined in URL [file:/E:/tomcat-6.0.18/Tomcat%206.0/webapps/wulindemo/WEB-INF/classes/memcaches.xml]: Instantiation of bean failed; nested exception is 
配置的bean名字和你实例化的不同。或者就没有实例化。还有你配置的property是否全部对应

Answer 5

少了某个jar：
nested exception is java.lang.NoClassDefFoundError: com/danga/MemCached/MemCachedClient
