本文整理了Java中org.apache.commons.lang3.StringUtils.indexOfIgnoreCase()方法的一些代码示例，展示了StringUtils.indexOfIgnoreCase()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。StringUtils.indexOfIgnoreCase()方法的具体详情如下：
包路径：org.apache.commons.lang3.StringUtils
类名称：StringUtils
方法名：indexOfIgnoreCase

StringUtils.indexOfIgnoreCase介绍

[英]Case in-sensitive find of the first index within a CharSequence.

A null CharSequence will return -1. A negative start position is treated as zero. An empty ("") search CharSequence always matches. A start position greater than the string length only matches an empty search CharSequence.

StringUtils.indexOfIgnoreCase(null, *)          = -1 
StringUtils.indexOfIgnoreCase(*, null)          = -1 
StringUtils.indexOfIgnoreCase("", "")           = 0 
StringUtils.indexOfIgnoreCase("aabaabaa", "a")  = 0 
StringUtils.indexOfIgnoreCase("aabaabaa", "b")  = 2 
StringUtils.indexOfIgnoreCase("aabaabaa", "ab") = 1

[中]字符序列中第一个索引的区分大小写的查找。
空字符序列将返回-1。负起始位置被视为零。空（“”）搜索字符序列始终匹配。大于字符串长度的起始位置仅与空搜索字符序列匹配。

StringUtils.indexOfIgnoreCase(null, *)          = -1 
StringUtils.indexOfIgnoreCase(*, null)          = -1 
StringUtils.indexOfIgnoreCase("", "")           = 0 
StringUtils.indexOfIgnoreCase("aabaabaa", "a")  = 0 
StringUtils.indexOfIgnoreCase("aabaabaa", "b")  = 2 
StringUtils.indexOfIgnoreCase("aabaabaa", "ab") = 1
