通过文件名获得路径和绝度路径
1 public class ClassloderGetpath {
2 public static void main(String[] args) throws IOException {
3 //创建properties
4 Properties pro = new Properties();
5
6 //通过src下的文件名获取绝对路径
7 URL resource = InputStreamDemo.class.getClassLoader().getResource("prop.properties");
8 String path = resource.getPath();
9 System.out.println(path);
10
11 //使用类加载器获得输入流
12 InputStream resourceAsStream = ClassloderGetpath.class.getClassLoader().getResourceAsStream("abcd.properties");
13 //将类加载
14 pro.load(resourceAsStream);
15 //获取键值对
16 String username = pro.getProperty("username");
17
18 System.out.println(username);
19 }
20 }
