java读取resource目录下的properties或txt文档笔记

假设Resource文件夹下有两文件：

1. demo1.properties

   demo1内容：
   name= chenhao
   age= 23

2. demo2.txt

public class ReadFromResourceFolder{
	
	// 读取properties文件
    public static void readProperties() throws IOException {
      //读取properties类型文件
        ResourceBundle bundle = ResourceBundle.getBundle("demo1");
        System.out.println(bundle.getString("name"));
        Demo1 demo = new Demo1();
        demo.readResources();
    }

    // 读取txt文件
    public void readResources() throws IOException{
            InputStream inputStream = this.getClass().getResourceAsStream("/demo2.txt");
            BufferedReader reader = null;
            List list = new ArrayList<>();
            try{
                reader = new BufferedReader(new InputStreamReader(inputStream));
                String str = null;
                while((str = reader.readLine()) != null){  //按行读取文件内容
                    list.add(str);
                }
                System.out.println(list));
            }catch ( Exception e){
                e.printStackTrace();
            }
        }
}

需要注意的是：txt文件需要直接在resource文件夹下才能被读取到。
