Spring 3.1 @Cacheable - 方法仍然执行

我正在尝试按照解释实现 Spring 3.1 缓存here http://www.javacodegeeks.com/2011/02/spring-31-cache-abstraction-tutorial.html and here http://blog.springsource.org/2011/02/23/spring-3-1-m1-caching/，但它似乎不起作用：我的方法每次都会运行，即使它被标记为@cacheable。我究竟做错了什么？

我已将其移至带有自己的配置文件的 junit 测试用例中，以将其与应用程序的其余部分隔离，但问题仍然发生。以下是相关文件：

Spring-test-servlet.xml

MyTest.java

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"classpath:spring-test-servlet.xml"})
@Component
public class MyTest extends TestCase {

    @Test
    public void testCache1(){
        for(int i = 0; i < 5; i++){
            System.out.println("Calling someMethod...");
            System.out.println(someMethod(0));
        }
    }

    @Cacheable("testmethod")
    private int someMethod(int val){
        System.out.println("Not from cache");
        return 5;
    }
}

相关 Pom 条目：（spring-version = 3.1.1.RELEASE）

当我运行测试时，Spring 会发出一些调试消息，看起来我的缓存已初始化，没有错误

但调试输出显示对 someMethod 的方法调用和每次从 someMethod 内部打印的打印语句之间没有缓存检查。

我有什么遗漏的吗？

在代理模式（默认）下，仅外部方法调用 通过代理传入的内容会被拦截。这意味着 实际上，自我调用，目标对象调用的方法 目标对象的另一个方法, 不会导致实际的 缓存在运行时即使调用的方法被标记为 @Cacheable - 在这种情况下考虑使用aspectj模式。

方法可见性和@Cacheable/@CachePut/@CacheEvict

使用代理时，您应该应用@Cache注释仅用于 方法与公众知名度.

1. 你自己调用someMethod在同一个目标对象中。
2. Your @Cacheable方法不公开。
