[springboot bug] mac 文件读取灵异事件

一开始是想尝试一下spring在过去的xml文件配置bean 的感觉，但是在测试 FileSystemXmlApplicationContext 的时候，反复确认文件路径没有问题，将 / -> \\ 也不起作用，后决定debug一下，发现根因。记录一下，方便springboot 的新人参考。（声明，开发我不会使用到这个方式创建 bean）

测试代码

package com.example.show_bean;import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;public class ApplicationContextTest {public static void main(String[] args) {testFileSystemXmlApplicationContext();}/*** 基于磁盘路径的 xml 配置文件来创建*/private static void testFileSystemXmlApplicationContext() {FileSystemXmlApplicationContext context = new FileSystemXmlApplicationContext("/Users/xx/project/java/easy_spring_mvc/learn_spring/show_bean/src/test/resources/b01.xml");System.out.println(context.getBean(Bean2.class).getBean1());}/*** java 配置类来创建*/private static void testAnnotationConfigApplicationContext() {}public static class Bean1 {Bean1() {System.out.println(">>>>>>>>>> 1");}}public static class Bean2 {private Bean1 bean1;public Bean2() {System.out.println(">>>>>>>>>>>> 2.");}public void setBean1(Bean1 bean1) {this.bean1 = bean1;}public Bean1 getBean1() {return bean1;}}}
