为什么没有为Jersey控制器检测到我的Aspect(使用自定义注释)？

Question

我想在Jersey控制器上创建一个Aspect来衡量服务执行的时间.我正在反对我的切入点,因为它没有被检测到,我的方面永远不会被启动.

我尝试过使用许多切入点,例如:

execution(@Monitor * *.*(..))
execution(public * *(..))
change the order of @Aspect and @Component

Added a pointcut like this:
@Pointcut("execution(@Monitor * *.*(..))")
public void monitorRequestTargets(){}
@Around("monitorRequestTargets()")

Tried using AOP and CGLIB
<aop:aspectj-autoproxy proxy-target-class="true"/>

Also tried changing the order of configuration in context.xml

Eclipse检测到我的方法正在建议我的方法,但它不会在运行时执行.你能否给我一些提示,说明为什么没有创建方面或切入点没有启动？

我的代码如下.

的context.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/mvc"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:beans="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"

        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">

    <!-- Enables the Spring MVC @Controller -->
    <annotation-driven />

    <!-- Enables AspectJ -->
    <aop:aspectj-autoproxy />

    <!-- .....more definitions -->

    <context:component-scan base-package="com.mypackage" />

</beans:beans>

我的MonitorAspect

@Component
@Aspect
public class MonitorAspect
{
    private static final Logger logger = LoggerFactory.getLogger(MonitorAspect.class);

    @Around("@annotation(com.mypackage.Monitor)")
    public void logTimeUsage(ProceedingJoinPoint joinPoint) throws Throwable 
    {
        // Store executing method
        String method = joinPoint.getSignature().getName();

        // Track time
        long startTime = System.currentTimeMillis();
        joinPoint.proceed();
        long endTime = System.currentTimeMillis();

        long duration = endTime - startTime;

        // Log time consumed by executing method
        logger.info(method + ": " + duration);

    }
}

我的Monitor自定义注释是

@Target(value = {ElementType.METHOD})
@Retention(value = RetentionPolicy.RUNTIME)
public @interface Monitor
{

}

我想要使​​用方面的控制器:

    @Monitor
    @POST
    @Consumes("application/json")
    @Produces("application/json")
    @Path("/{tkn}/test/")
    public Response test(
            @Context HttpServletRequest httpReq,
            @Context UriInfo uri,
                     String enrollReqJson
            ) {
          Thread.sleep(1000); // Implementation is not important
    }

Answer 1

我发现为什么我的方面不能与 Jersey 一起使用，因为我必须在这种特殊情况下使用编织器。

配置aspectj-maven-plugin来编织我的方面后，一切都成功进行。

配置编织器的完整详细信息可以在此答案中找到： Spring + AspectJ weaving for java 8 usingspectj-maven-plugin
