Spring Cache注解+Memcached

Spring3.1 Cache注解

依賴jar包：

<!-- simple-spring-memcached -->
    <dependency>
      <groupId>com.google.code.simple-spring-memcached</groupId>
      <artifactId>simple-spring-memcached</artifactId>

<!-- 啟用緩存注解功能，這個是必須的，否則注解不會生效，另外，該注解一定要聲明在spring主配置文件中才會生效 -->
  <cache:annotation-driven cache-manager="cacheManager" />

<!-- spring自己的換管理器，這里定義了兩個緩存位置名稱 ，既注解中的value -->
