我试图按照解释的here和here来实现Spring 3.1缓存,但它似乎并不奏效: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?Spring 3.1 @Cacheable - 仍然执行的方法
我已经将它与自己的配置文件一起移动到junit测试用例中,以将它与其他应用程序隔离开,但问题仍然存在。以下是相关文件:
弹簧试验servlet.xml中

MyTest.java
@RunWith(SpringJUnit4ClassRunner.class)

@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;
}
}

当我运行测试,春天推出,看起来像我的缓存是没有错误

初始化,但调试输出显示没有缓存检查之间的方法调用的someMethod和print语句一些调试消息每次在someMethod中打印。
有什么我失踪了吗?
除了这个方法的问题,您需要提取到一个接口,所以Spring可以动态地为你的类写封装。 – RockMeetHardplace 2012-05-10 01:01:00
