方面没有被执行

Question

我们在函数上有一个注释如下

public class AnInterfaceImpl implements AnInterface {
    @FairThreadUsageByEntity(entityName = "XYXYXYX",
    numberOfThreads = 1)
    public Report getReport(final String One, final String Two) {
        //implementation.
    }
}

public interface AnInterface {
    String BEAN_NAME = "AnInterface";   //used for injection in spring.
    Report getReport(final String One, final String two);
}

弹簧配置:

<aop:aspectj-autoproxy />
<bean class="com.amazon.utils.fairthreadusage.aspect.FairThreadUsageByEntityAdvice" />

注释作为一个方面实现.基本功能是限制特定类型功能使用的线程数,让我们说下载.以下是注释的代码FairThreadUsageByEntity:

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface FairThreadUsageByEntity {
    public String entityName();
    public int numberOfThreads();
}

@Aspect
public class FairThreadUsageByEntityAdvice extends FairThreadUsageBase {

    @Around("@annotation(fairUsage)")
    public Object fairThreadUsageByEntity(final ProceedingJoinPoint pjp, final FairThreadUsageByEntity fairUsage)
            throws Throwable {  
        //Implementation
    }
}

注释无论如何都不起作用.我正在使用AspectJWeaver 1.7和java 1.7.如果还有其他需要,请告诉我.任何帮助赞赏.

编辑:添加控制器,调用getReport函数

public class ReportDownloadRootController extends BaseRootController {
    public static final String REQUEST_MAPPING_REPORT_DOWNLOAD = "/hz/inventory/addproducts/status/report";
    public static final String PARAM_REFERENCE_ID = "reference_id";
    private AnInterface anInterface;

    @RequestMapping(REQUEST_MAPPING_REPORT_DOWNLOAD)
    public void execute(@RequestParam(value = PARAM_REFERENCE_ID, required = true) final String referenceId,
        final HttpServletRequest request, final HttpServletResponse response) {
        try {

            Report report = AnInterface.getReport(referenceId, getContext().getMerchantId());    //breakpoint here
        } catch {
            //something
        }
    }
    @Resource(name = AnInterface.BEAN_NAME)
    public void setAnInterface(final AnInterface anInterface) {
        this.anInterface = anInterface;
    }
}

编辑2:Spring bean for AnInterface

<bean id="AnInterface" class="com.facade.feed.AnInterfaceImpl" />

我创建了简单的项目，其中包含您提供的所有信息，并且无法在简单的设置中重现您的问题，因此您可以正确实现您的 bean/方面。

一个可能且常见的错误是在一个上下文中定义方面，而在另一个上下文中定义 bean，例如，方面是在 中定义的applicationContext，而 bean 是在 中定义的dispatcherServletContext。在这种配置方面，不适用于 child 中定义的 bean dispatcherServletContext，仅适用于parentapplicationContext
