类名称：StringUtils
方法名：compareIgnoreCase

StringUtils.compareIgnoreCase介绍

[英]Compare two Strings lexicographically, ignoring case differences, as per String#compareToIgnoreCase(String), returning :

• int = 0, if str1 is equal to str2 (or both null)
• int < 0, if str1 is less than str2
• int > 0, if str1 is greater than str2

This is a null safe version of :

str1.compareToIgnoreCase(str2)

null value is considered less than non- null value. Two null references are considered equal. Comparison is case insensitive.

StringUtils.compareIgnoreCase(null, null)   = 0 
StringUtils.compareIgnoreCase(null , "a")   < 0 
StringUtils.compareIgnoreCase("a", null)    > 0 
StringUtils.compareIgnoreCase("abc", "abc") = 0 
StringUtils.compareIgnoreCase("abc", "ABC") = 0 
StringUtils.compareIgnoreCase("a", "b")     < 0 
StringUtils.compareIgnoreCase("b", "a")     > 0 
StringUtils.compareIgnoreCase("a", "B")     < 0 
StringUtils.compareIgnoreCase("A", "b")     < 0 
StringUtils.compareIgnoreCase("ab", "ABC")  < 0

[中]根据字符串#CompareTionIgnoreCase（字符串），忽略大小写差异，按字典顺序比较两个字符串，返回：
*int=0，如果str1等于str2（或两者都为null）
*int<0，如果str1小于str2
*int>0，如果str1大于str2
这是以下内容的空安全版本：

str1.compareToIgnoreCase(str2)

空值被认为小于非空值。两个空引用被视为相等。比较不区分大小写。

StringUtils.compareIgnoreCase(null, null)   = 0 
StringUtils.compareIgnoreCase(null , "a")   < 0 
StringUtils.compareIgnoreCase("a", null)    > 0 
StringUtils.compareIgnoreCase("abc", "abc") = 0 
StringUtils.compareIgnoreCase("abc", "ABC") = 0 
StringUtils.compareIgnoreCase("a", "b")     < 0 
StringUtils.compareIgnoreCase("b", "a")     > 0 
StringUtils.compareIgnoreCase("a", "B")     < 0 
StringUtils.compareIgnoreCase("A", "b")     < 0 
StringUtils.compareIgnoreCase("ab", "ABC")  < 0
