Java獲取路徑（getResource）

package com.zhi.test;

public class PathTest {
    public static void main(String[] args) {
        System.out.println(PathTest.class.getResource(""));
        System.out.println(PathTest.class.getResource("/"));

        System.out.println(PathTest.class.getClassLoader().getResource(""));
        System.out.println(PathTest.class.getClassLoader().getResource("/"));

        System.out.println(ClassLoader.getSystemResource(""));
        System.out.println(ClassLoader.getSystemResource("/"));

        System.out.println(System.getProperty("user.dir"));
    }
}

對應數據的路徑如下：
