Spring AOP:获取切入点注解的参数 [英] Spring AOP: Getting parameters of the pointcut annotation

问题描述

考虑我已经定义了以下方面:

Consider I have defined the following aspect:

@Aspect
public class SampleAspect {

    @Around(value="@annotation(sample.SampleAnnotation)")
    public Object display(ProceedingJoinPoint joinPoint) throws Throwable {
        // ...
    }
}

和注释

public @interface SampleAnnotation {
    String value() default "defaultValue";
}

如果是我的aspect，有没有办法读取display方法中注解SampleAnnotation的value参数?

Is there a way to read the value parameter of the annotation SampleAnnotation in the display method if my aspect?

感谢您的帮助，埃里克

推荐答案

将通知签名更改为

@Around(value="@annotation(sampleAnnotation)")
public Object display(ProceedingJoinPoint joinPoint, SampleAnnotation sampleAnnotation ) throws Throwable {
    // ...
}

您将可以访问注释中的值.

and you will have access to the value in the annotation.
