nutz的版本1.r.62
```java
@IocBean
public class RemoteCacheService extends RedisService {
}

测试代码
public class RemoteCacheServiceTest {
private Ioc ioc;
@Before
public void before() throws ClassNotFoundException {
JsonLoader jsonLoader = new JsonLoader("/config");
AnnotationIocLoader annoLoader = new AnnotationIocLoader("/com/weirhp");
IocLoader iocLoader = new ComboIocLoader("*jedis");
IocLoader iocLoader2 = new ComboIocLoader(jsonLoader, annoLoader, iocLoader);
ioc = new NutIoc(iocLoader2);
}

    // 有问题
@Test
public void testSet() throws InterruptedException {
       RemoteCacheService cacheService = ioc.get(RemoteCacheService.class);
       cacheService.set("test", "111");
}

   // 没问题
   @Test
public void testSet2() throws InterruptedException {
    RedisService cacheService = ioc.get(RedisService.class);
    cacheService.set("test", "111");
}

}

```

@IocBean(fields="jedisAgent")

要在启动的@IocBy中申明引入"*jedis"

还是不行,异常信息如下:
