本文整理了Java中org.apache.commons.io.IOUtils.readLines()方法的一些代码示例，展示了IOUtils.readLines()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。IOUtils.readLines()方法的具体详情如下：
包路径：org.apache.commons.io.IOUtils
类名称：IOUtils
方法名：readLines
[英]Get the contents of an InputStream as a list of Strings, one entry per line, using the default character encoding of the platform.
This method buffers the input internally, so there is no need to use a BufferedInputStream.
[中]使用平台的默认字符编码，以字符串列表的形式获取InputStream的内容，每行一个条目。
此方法在内部缓冲输入，因此无需使用BufferedInputStream。
