请问一下,我这样写有什么问题嘛?为什么通过方法注入找不到beanId?

@Configuration
@ComponentScan("com.qin5")
public class TestConfiguration5 {

}


@Component(value = "testBean15")
@Scope("singleton")
public abstract class TestBean5 {
    @Lookup
    public abstract AnotherBean5 createAnotherBean5();

    public void printBean() {
        System.out.println(createAnotherBean5());
    }
}

@Component
@Scope("prototype")
public class AnotherBean5 {
}
@Test
public void test5() {
    AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(TestConfiguration5.class);
    TestBean5 testBean1 = context.getBean("testBean15", TestBean5.class);
    testBean1.printBean();
    testBean1.printBean();
    testBean1.printBean();
    testBean1.printBean();
    testBean1.printBean();
    testBean1.printBean();

}
