本文整理了Java中org.apache.commons.io.FileUtils.toFile()方法的一些代码示例，展示了FileUtils.toFile()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。FileUtils.toFile()方法的具体详情如下：
包路径：org.apache.commons.io.FileUtils
类名称：FileUtils
方法名：toFile

FileUtils.toFile介绍

[英]Convert from a URL to a File.

From version 1.1 this method will decode the URL. Syntax such as file:///my%20docs/file.txt will be correctly decoded to /my docs/file.txt. Starting with version 1.5, this method uses UTF-8 to decode percent-encoded octets to characters. Additionally, malformed percent-encoded octets are handled leniently by passing them through literally.
[中]从URL转换为File。
从版本1.1开始，此方法将解码URL。file:///my%20docs/file.txt等语法将正确解码为/my docs/file.txt。从版本1.5开始，此方法使用UTF-8将百分比编码的八位字节解码为字符。此外，格式错误的百分比编码八位字节可以通过字面上的传递来轻松处理。
