本文整理了Java中org.apache.commons.io.input.XmlStreamReader.<init>()方法的一些代码示例，展示了XmlStreamReader.<init>()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。XmlStreamReader.<init>()方法的具体详情如下：
包路径：org.apache.commons.io.input.XmlStreamReader
类名称：XmlStreamReader
方法名：<init>

XmlStreamReader.<init>介绍

[英]Creates a Reader for a File.

It looks for the UTF-8 BOM first, if none sniffs the XML prolog charset, if this is also missing defaults to UTF-8.

It does a lenient charset encoding detection, check the constructor with the lenient parameter for details.
[中]为文件创建读取器。
它首先查找UTF-8 BOM，如果没有嗅探XML prolog字符集，如果也缺少，则默认为UTF-8。
它执行宽松的字符集编码检测，请使用lenient参数检查构造函数以了解详细信息。
