测试类：

public class CacheUtil {
    private Log log = LogFactory.getLog(CacheUtil.class);
    private MemCachedClient cachedClient = null;

    @Before
    public void init() {
        ApplicationContext context = new ClassPathXmlApplicationContext(
            "application_memcached.xml");
        cachedClient = (MemCachedClient) context.getBean("memcachedClient");
    }

    @Test
    public void testCache() {
        cachedClient.add("hello", "world");
        String s = (String) cachedClient.get("hello");
        log.info(s);
        Assert.assertEquals("world", s);
    }
}
