加载多个属性文件 [英] Loading multiple properties files

问题描述

是否可以在 Java 中堆叠加载的属性?例如我可以做:

Is it possible to stack loaded properties in Java? For instance can I do:

Properties properties = new Properties();

properties.load(new FileInputStream("file1.properties"));
properties.load(new FileInputStream("file2.properties"));

并从两者访问属性?

推荐答案

您可以这样做:

Properties properties = new Properties();

properties.load(new FileInputStream("file1.properties"));

Properties properties2 = new Properties();
properties2.load(new FileInputStream("file2.properties"));

properties.putAll(properties2);

注意:维护的所有密钥都是唯一的.因此，稍后加载相同键的属性将被覆盖.只是为了你的参考:)

NOTE : All the keys maintained are unique. So, the later properties loaded with same key will be overridden. Just to keep for your ref :)
