Question

执行AspectJ切入点时遇到问题。我的方面是：

@Component
@Aspect
public class UploadToDefaultAspect {
private static Logger logger = Logger.getLogger(UploadToDefaultAspect.class);
private Sardine sardine;
private String webCloudDataDir;

@Autowired private ConfigurationFactory configuration;
@Autowired private GeoProcessorDAO geoService;

@PostConstruct
private void init() {
    webCloudDataDir = configuration.getConfigurationValue(DEFAULT_CLOUD_LOCATION) + DIR_CLOUD_DATA;
}

@AfterReturning(
        pointcut = "execution(* web.service.SystemService.uploadGeoTZCSV(..))", 
        returning = "country")
    public void uploadAfterReturning( Country country ) throws CloudException {
    // upload stuff
    }
}

web.service.SystemService是一个包含uploadGeoTZCSV：

等几种方法的接口

Country uploadGeoTZCSV( MultipartFile geoTZFile ) throws CSVUploadException;

当我调试uploadGeoTZCSV时它可以正常工作但是方法根本不调用（它由Spring管理，我在日志中看到了init（）的调用）。我也在applicationContext.xml中配置了aop：

<aop:aspectj-autoproxy proxy-target-class="true"/>

Spring 4.2.3.RELEASE，AspectJ 1.8.7：

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-aop</artifactId>
        <version>4.2.3.RELEASE</version>
    </dependency>
    <!-- AspectJ -->
    <dependency>
        <groupId>org.aspectj</groupId>
        <artifactId>aspectjrt</artifactId>
        <version>1.8.7</version>
    </dependency>
    <dependency>
        <groupId>org.aspectj</groupId>
        <artifactId>aspectjweaver</artifactId>
        <version>1.8.7</version>
    </dependency>

我哪里错了？

谢谢。

更新1 。当我将AOP配置移动到XML时，它也不起作用：

    <aop:aspectj-autoproxy/>

<!-- AOP beans -->
<bean id="uploadToDefaultAspect" class="web.aop.UploadToDefaultAspect" init-method="init"/>
<aop:config>
    <aop:aspect id="uploadToDefaultAspect" ref="uploadToDefaultAspect">
        <!-- @AfterReturning -->
        <aop:pointcut id="pointCutAfterReturning"
            expression="execution(* web.service.SystemService.uploadGeoTZCSV(..))"/>
         <aop:after-returning method="uploadGeoTZCSVAfterReturning" returning="country" 
            pointcut-ref="pointCutAfterReturning"/>
    </aop:aspect>
</aop:config>

发生了什么事？

最后，我找到了一个解决方案 - 只需将@EnableAspectJAutoProxy添加到web.service.SystemService的实现中：

@Service
@EnableAspectJAutoProxy
public class SystemServiceImpl implements SystemService {

AspectJ：@AfterReturning方法没有调用
