SPRING文本上下文 - AOP注释

Question

我不明白为什么我的2测试相同的AOP结果。 =＆GT;测试1调用AOP（@After和@AfterThrowing），但测试2。 你能帮助我吗 ？我想直接使用spring inject而不用getBeans ...

测试类

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "/applicationcontext.xml" })
@TestExecutionListeners(listeners = {
    DependencyInjectionTestExecutionListener.class,
    DirtiesContextTestExecutionListener.class,
    TransactionalTestExecutionListener.class })
@Component("Testing")
public class Testing {

private final static Logger logger = LoggerFactory
        .getLogger(Testing.class);

@Autowired
ApplicationContext context;

@Test
public void testAOP() {
    logger.info("\n\n ********* test 1    // AOP");

    Testing testing = (Testing) context.getBean("Testing");
    logger.info("Object 1 = " + testing.toString());
    logger.info(testing.findBar());
}

@Test
public void testAOP2() {
    logger.info("\n\n ********* test 2    // AOP");

    logger.info("Object 2 = " + this.toString());
    logger.info(this.findBar());

}


public String findBar() {
    String tst = null;

    //LEVE ERRREUR
    if (tst.length() > 2)
        logger.error("Impossible");

    logger.error("Impossible");
    return "tst";
}

}
