Spring AOP表达式抛出java.lang.IllegalArgumentException:警告此类型名称不匹配[...]

我是Spring AOP的新手,我非常不安......

我运行JBoss 7.2,Mojara 2.2.2和Spring 3.1.2.RELEASE。

我有以下dispatcher-servlet.xml

<mvc:annotation-driven />
<context:annotation-config />
<aop:aspectj-autoproxy  proxy-target-class="true" />
<context:component-scan base-package="com.project.scheduler" />
<task:annotation-driven scheduler="taskScheduler" />
<task:scheduler id="taskScheduler" pool-size="2" />

这是我的方面:

@Aspect
@Component
public class BatchHistorizerAspect implements Serializable {

    private static final long  serialVersionUID = 2620746940572873202L;
    public static final Logger LOGGER           = LogManager.getLogger(BatchHistorizerAspect.class);

    @Around("execution(* com.project.scheduler.StatusCleanScheduler.schedule(..))")
    public void aroundSchedule(ProceedingJoinPoint jp) {
        LOGGER.debug("aroundSchedule start");
        try {
            jp.proceed();
        } catch (Throwable e) {
            LOGGER.debug("aroundSchedule exception:", e);
        }
        LOGGER.debug("aroundSchedule end");
    }
}

最后我想要建议的课程:

@Component
public class StatusCleanScheduler implements Serializable {

    private static final long       serialVersionUID = -8061115218184844863L;
    private final static Logger     LOGGER           = LogManager.getLogger(StatusCleanScheduler.class);

    @Autowired
    private StatusService statusService;

    @Override
    @Scheduled(cron = "0 * * * * *")
    public void schedule() {
        LOGGER.info("Start Status orphans cleaning");
        statusService.cleanOrphans();
        LOGGER.info("End Status orphans cleaning");
    }
}

当我启动服务器时,会抛出以下内容:

ERROR [ServerService Thread Pool -- 54] org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/agathe]: JBWEB000289: Servlet dispatcher threw load() exception: java.lang.IllegalArgumentException: warning no match for this type name: com.project.scheduler.StatusCleanScheduler [Xlint:invalidAbsoluteTypeName]
    at org.aspectj.weaver.tools.PointcutParser.parsePointcutExpression(PointcutParser.java:301) [aspectjweaver-1.6.12.jar:1.6.12]
    at org.springframework.aop.aspectj.AspectJExpressionPointcut.buildPointcutExpression(AspectJExpressionPointcut.java:207) [spring-aop-3.1.2.RELEASE.jar:3.1.2.RELEASE]
    at org.springframework.aop.aspectj.AspectJExpressionPointcut.getFallbackPointcutExpression(AspectJExpressionPointcut.java:358) [spring-aop-3.1.2.RELEASE.jar:3.1.2.RELEASE]
    at org.springframework.aop.aspectj.AspectJExpressionPointcut.getShadowMatch(AspectJExpressionPointcut.java:409) [spring-aop-3.1.2.RELEASE.jar:3.1.2.RELEASE]
...

但当我将@Around更改为@Around("execution(* com.project.scheduler.*.schedule(..))")时,一切正常,我的方面被正确调用。

我做错了什么?

更新:

我做了一些解决方法,但我觉得很脏......

@Around("execution(* com.project.scheduler.*.schedule(..))")
public void aroundSchedule(ProceedingJoinPoint jp) {
    Object obj = jp.getThis();
    if (!(obj instanceof StatusCleanScheduler)) {
        jp.proceed();
        return;
    }
    StatusCleanScheduler batch = (StatusCleanScheduler) obj;
    LOGGER.debug("aroundSchedule start");
    try {
        jp.proceed();
    } catch (Throwable e) {
        LOGGER.debug("aroundSchedule exception:", e);
    }
    LOGGER.debug("aroundSchedule end");
}

如果您有更好的解决方案,请告诉我。

答案 0 :(得分:0)

正如我在评论中所说,[Xlint:invalidAbsoluteTypeName]告诉您,您真实的,完全合格的班级名称与您在切入点中使用的名称不同。比较两者,你会发现一个容易修复的不匹配。也许这只是一个错字。

如果你想要更加防御性地编码,可以使用这样的通配符,这样你就可以在你的班级中移动到子包中,如果你愿意的话:

StatusCleanScheduler的任何子包中查找类com.project.scheduler(这可能是您想要的):

execution(* com.project.scheduler..StatusCleanScheduler.schedule(..))

仅供参考,您也可以这样做:

StatusCleanScheduler的任何子包中找到课程com.project

execution(* com.project..StatusCleanScheduler.schedule(..))

Scheduler的任何子包中找到以com.project结尾的类:

execution(* com.project..*Scheduler.schedule(..))

在项目中查找任何schedule方法:

execution(* com.project..schedule(..))
