访问通知中的注释值

问题描述

在我的应用程序中，我有这样注释的方法:

In my application I have methods annotated like this:

@SomeAnnotation(key1="value1", key2 ="value2")
public void myMethod()

我定义了以下 apsect 来执行这些方法的执行操作:

I have defined the following apsect to perform some action on executing of those methods:

@Aspect
public class MyAspect()
{
    @Around("@annotation(my.package.SomeAnnotation)")
    public Object doSomething(final ProceedingJoinPoint pjp) throws Throwable
    {
        ...
    }
}

现在我想在我的建议中使用注释值(上面例子中的value1"和value2").此时访问注解的方式是什么?

Now I would like to use the annotation values ("value1" and "value2" in the above example) inside my advice. What is the way to access the annotation at this point?

推荐答案

@annotation 可以使用绑定形式，如下:

@annotation can be used in binding form, as follows:

@Around(value = "@annotation(a)", argNames = "a")
public Object doSomething(final ProceedingJoinPoint pjp, SomeAnnotation a)
    throws Throwable { ... }
