问题 I have a custom annotation as, @Target({ElementType.METHOD}) @Retention(RetentionPolicy.RUNTIME) public @interface XAudit { AuditActionType action(); } I am using this annotation on some method as following, @XAudit(action = "REGISTRATION") public RegistrationDTO register(UserDetail detail) { //Logic return dto; } I am capturing event in aspect as following, @Around(value = "@annotation(XAudit)") public Object postAuditEvent(ProceedingJoinPoint joinPoint, XAudit xAudit) throws Throwable {

问题 I have this class in my Spring Web model-view-controller (MVC) framework. I am using aspect-oriented programming (AOP), a programming paradigm that aims to increase modularity by allowing the separation of cross-cutting concerns. Everything is fine with this class @Aspect public class MarketingAspect extends ServiceSupport { @Pointcut("execution(* com.tdk.iot.services.client.LicenseService.*(..))") public void handleServiceMethod() { } @Pointcut("execution(* com.tdk.iot.services.client

问题 Can I apply the @Transactional tag to an aspect advice? I'm trying to wrap all calls to the service layer (com.mycompany.app.myapp.service.*) in a transaction using aspects. My aspect is properly intercepting the calls to the service layer, but I can't figure out how to start a transaction. I thought I could apply the @Transactional tag and because I've got the tag, it'd pick it up and begin the transaction. What am I missing? XML configuration: <bean id="systemArchitectureAspect" class="com

问题 I'm essentially trying to track the number of transfers for an Account class. Reading the docs here: https://www.eclipse.org/aspectj/doc/released/progguide/language-anatomy.html And on slide 48 and 49 here: https://www.eclipse.org/aspectj/doc/released/progguide/language-anatomy.html These tell me I should be able to do something like this: public aspect LoggingAspect { private int Account.transferCount = 0; private int Account.getTransferCount() { return transferCount; } pointcut

问题 I have been going through some Spring / AOP tutorials and have somewhat familiarized myself with the related concepts. Now coming to my requirements, I need to create an Activities Log implementation which will save the activities of a logged-in user in the DB which can range from applying for a service or creating new users in case of Admin users, etc. On invocation of any method having an annotation (say @ActivityLog ), this information is to be persisted in the form of actorId ,

问题 Spring manual says: any join point (method execution only in Spring AOP) where the target object has an @Transactional annotation: @target(org.springframework.transaction.annotation .Transactional) any join point (method execution only in Spring AOP) where the declared type of the target object has an @Transactional annotation: @within(org.springframework.transaction.annotation .Transactional) But I not see any difference between them! I tried to Google it: One difference between the two is
