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 {
String action = xAudit.action(); //Accessing Action for logic decision making
Object result = joinPoint.proceed();
//audit processing logic
return result;
}
The @Around advice works well with only ProceedingJoinPoint argument. If passing XAudit as 2nd argument, it throws following error,
Error creating bean with name 'metaDataSourceAdvisor': Cannot resolve reference to bean 'methodSecurityMetadataSource' while setting constructor argument; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.security.config.annotation.method.configuration.GlobalMethodSecurityConfiguration': Unsatisfied dependency expressed through method 'setObjectPostProcessor' parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.config.annotation.configuration.ObjectPostProcessorConfiguration': Initialization of bean failed; nested exception is java.lang.IllegalArgumentException:

I need to use xAudit inside aspect in order to access action of XAudit. Kindly share some pointers on how can I access the value of @XAudit inside @Around Aspect.
回答1:
There is a typo in the @Around(value = "@annotation(XAudit)")
, it should be xAudit
( x is lower case)
Try : @Around(value = "@annotation(xAudit)")
Also , to get the action value from annotation you need to use xAudit.action()
and not xAudit.getAction()
.
Complete code would be as follows
@Component
@Aspect
public class XAuditAspect {
@Around(value = "@annotation(xAudit)")
public Object postAuditEvent(ProceedingJoinPoint joinPoint, XAudit xAudit) throws Throwable {
String action = xAudit.action(); //Accessing Action for logic decision making
Object result = joinPoint.proceed();
//audit processing logic
System.out.println(xAudit.action());
return result;
}
}
