Java获取路径（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"));
    }
}

对应数据的路径如下：

file:/E:/workspace/javaee/test/target/test-classes/com/zhi/exportword/
file:/E:/workspace/javaee/test/target/test-classes/
file:/E:/workspace/javaee/test/target/test-classes/
null
file:/E:/workspace/javaee/test/target/test-classes/
null
E:\workspace\javaee\test
