动态值不作为注释中的属性支持-AspectJ Android [AOP Android] [英] Dynamic values are not supported as attributes in annotation- AspectJ Android [AOP Android]

问题描述

我正在使用自定义注释来记录用户单击的ID.但是出现错误"属性值必须为常数".我的代码段如下.

I am using custom annotation to log the id which user clicked. But I am getting a error "Attribute value must be a constant". My code snippet is below.

mAssetId= Asset.getContentId();

  @TrackEvent("track_event")
    @ArrayParams({@Params(key = "content_id",value = mAssetId)})
    protected void attributeMethod() {
    }

先谢谢了.有什么方法可以在注释中传递动态值，而不是静态变量或常量.我正在为Android使用 AspectJ 库.

Thanks in advance. Is there any way to pass dynamic values in annotation rather than static variables or constants. I am using AspectJ library for android.

推荐答案

不可能在注释属性中指定运行时值，只能指定常量，甚至可能的类型集也仅限于以下几种类型:

It's not possible to specify runtime values in annotation attributes, only constants, and even the set of possible types is limited to a few types:

上述类型的基元，字符串，类，枚举，注释和数组

primitives, String, Class, enums, annotations, and arrays of the preceding types

根据 Java 5语言指南-注释.
