在使用DOM4j解析XML时遇到错误，问题源于文件路径中包含中文字符，导致解析失败。解决方案是将文件路径修改为非中文，确保DOM4j能正确识别。此问题提醒开发者在处理文件路径时要注意编码兼容性。

出现原因

录入数据的时候部分字段包含中文,调用DOM4j解析xml功能报错如下:

unknown protocol: f Nested exception: unknown protocol: f

bug显示

控制台错误截图

解决办法

经尝试发现文件调用的路径中有中文，导致Dom4j不识别，将文件路径修改为中文即可.

URL报错：unknown protocol，未知协议 问题分析： 在使用new URL(filePath)出现此错误，原因是传入的字符串不是一个URL，所以无法识别。 解决方法： 若是本地文件，检查路径前面是否添加了file:// 示例：String filePath = "D:/Users/Administrator/Desktop/test.txt"; // 添加文件协议 filePath = "file://"+filePath; URL url = new URL(filePath); 2
URL报错: unknown protocol

unknown protocol: d我们需要在一个本地磁盘路径前面加上 file:// 来表示 URL 得到一个 file://d:/abc，不能直接 D:/abc 这种写法。 你的错误就在于直接用 d:/abc 当 URL，所以它报告错误说不认识 d 这种协议。String url = "file://" + filePath;unknown protocol: f解决办法：解析的文件名包括路
RedisConnectionFailureException；（原因就是：redis服务没启动）

开门见山，错误原因是：自己的redis服务器，我们只设置了redis后台运行，而没有把redis服务设置为系统服务，也就是没有设置redis开机自启；所以，自己不注意重启了redis所在的服务器，而忘记了开启redis服务；所以，会出现redis连不上的情况； 为什么写本篇博客？：在写【附加：Mybatis传递多个参数时的处理策略；（包括：是否使用@Param注解，parameterType=“”的使用，使用Map或者List接收；）】的时候，遇到了redis连不上的情况，报了如下的错误： or.

前言 呵呵 之前项目中会存在这样的一个情况 选择多个文件导入 : 假设选择多个文件(一般是十个以上), 偶尔会抛出如下异常, 呵呵 和 redis 相关, 但是看异常信息RejectedExecutionException 抛出的地方 又是在forkjoin 库里面 呵呵 这两者有什么关联呢? 这里就来看看, 呵呵 forkjoin 这部分的类库 有一些博大精深, 多久还得仔细看看, 说实话 看起来 还是很有难度 我这里 只是从解决问题的角度, 看了一些, 但是 但是还有很多不明白的地方...
