我有一个自定义注释,
@Target({ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
public @interface XAudit {
AuditActionType action();
}
我在某些方法上使用此注释,如下所示,
@XAudit(action = "REGISTRATION")
public RegistrationDTO register(UserDetail detail) {
//Logic
return dto;
}
我在方面捕获事件如下,
@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;
}
@Around 建议仅适用于 ProceedingJoinPoint 争论。如果通过 XAudit 作为第二个参数,它抛出以下错误,
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:

我需要使用 xAudit 内部方面以访问 行动的 XAudit .请分享一些有关如何访问@Around Aspect 中@XAudit 值的指针。
最佳答案
@Around(value = "@annotation(XAudit)")
中有错别字,应该是 xAudit
( x 是小写)
试试:@Around(value = "@annotation(xAudit)")
此外,要从注释中获取操作值,您需要使用 xAudit.action()
而不是 xAudit.getAction()
.
完整的代码如下
@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;
}
}
关于Spring AOP @Around 访问@annotation 的值,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/62298498/
