AspectJ:向类添加静态初始化器 [英] AspectJ: add static initializer to class

问题描述

我的某些Java类的静态方法带有特殊注释@Assert，其中包含健全性检查.

Some of my Java classes have static methods marked with a special annotation, @Assert, containing sanity checks.

我想在实际执行任何代码之前执行这些检查.最好是从<clinit>调用这些方法.如何在不修改初始代码的情况下使用AspectJ获得类似的行为?

I'd like to perform these checks before any code gets actually executed. The best would be to call these methods from <clinit>. How to get similar behavior using AspectJ, and without modifying initial code?

推荐答案

AspectJ提供了一个staticinitialization(TypePattern)切入点定义，该定义将选择现有的静态初始值设定项并对其进行拦截.但是，似乎无法向没有静态初始化程序的类中添加静态初始化程序.

AspectJ provides a staticinitialization(TypePattern) pointcut definition that will select existing static initializers and intercept them. Doesn't appear to be able to add static initializers to classes that don't have them, however.
