AspectJ - 无法识别连接点表达式中的注释

问题描述

在我的一个方面，我有以下方法:

In one of my aspects i have the following method:

@Before("execution (* org.xx.xx.xx..*.*(@Standardized (*),..))")
public void standardize(JoinPoint jp) throws Throwable {
}

目标是找到我的应用程序包的所有方法，这些方法至少有一个用@Standardized 注释的参数(不是用@Standardized 注释的类型不同)

The goal is to find all methods of my application packages which have at least one parameter annotated with @Standardized (not with a type annotated with @Standardized which is different)

ps:@Standardized 是自定义注解.

ps: @Standardized is a custom annotation.

从我在文档中读到的内容来看，此配置应该是正确的(如果不是，请告诉我)，但是当我在 JBoss 服务器下部署我的应用程序时，出现以下异常:

From what i've read on the documentation, this configuration should be the correct one (let me know if not), but when i deploy my application under a JBoss server, i have the following exception:

java.lang.IllegalArgumentException:警告不匹配此类型名称:标准化

java.lang.IllegalArgumentException: warning no match for this type name: Standardized

我尝试使用 (@Standardized *,..) 而不是 (@Standardized (*),..) (这不会产生我所知道的相同结果)，但我仍然遇到相同的错误.

I tried with (@Standardized *,..) instead of (@Standardized (*),..) (which would not have the same result i know) but i still have the same error.

有人知道为什么吗?

在此先感谢您的帮助.

问候.

推荐答案

除非 @Standardized 注释在默认包中，否则您需要为注释指定 FQN 名称或使用类似 的模式@*..标准化.

Unless @Standardized annotation is in default package, you need to specify FQN name for your annotation or use a pattern like @*..Standardized.
