反射:通过反射加载的类中的常量变量 [英] Reflection: Constant variables within a class loaded via reflection

问题描述

我有一个包含一堆常量字符串的类.

I have a class which has a bunch of Constant Strings.

我需要通过反射加载此类并检索那些常量.我可以起床:

I need to load this class via reflection and retrieve those constants. I can get up to:

controllerClass = Class.forName(constantsClassName);
Object someclass = controllerClass.newInstance();

但是我对如何检索此类中的字段感到困惑.

but I am confused on how to retrieve the fields in this class.

推荐答案

访问字段的快速示例-

Field[] fields = controllerClass.getDeclaredFields();

for ( Field field : fields ) {
   field.setAccessible(true);
  System.out.println(field.get(someClass));

}
