包路径：org.apache.commons.lang3.StringUtils
类名称：StringUtils
方法名：replaceFirst

StringUtils.replaceFirst介绍

[英]Replaces the first substring of the text string that matches the given regular expression with the given replacement.
This method is a null safe equivalent to:

• text.replaceFirst(regex, replacement)
• Pattern.compile(regex).matcher(text).replaceFirst(replacement)

A null reference passed to this method is a no-op.

The Pattern#DOTALL option is NOT automatically added. To use the DOTALL option prepend "(?s)" to the regex. DOTALL is also known as single-line mode in Perl.

StringUtils.replaceFirst(null, *, *)       = null 
StringUtils.replaceFirst("any", (String) null, *)   = "any" 
StringUtils.replaceFirst("any", *, null)   = "any" 
StringUtils.replaceFirst("", "", "zzz")    = "zzz" 
StringUtils.replaceFirst("", ".*", "zzz")  = "zzz" 
StringUtils.replaceFirst("", ".+", "zzz")  = "" 
StringUtils.replaceFirst("abc", "", "ZZ")  = "ZZabc" 
StringUtils.replaceFirst("<__>\n<__>", "<.*>", "z")      = "z\n<__>" 
StringUtils.replaceFirst("<__>\n<__>", "(?s)<.*>", "z")  = "z" 
StringUtils.replaceFirst("ABCabc123", "[a-z]", "_")          = "ABC_bc123" 
StringUtils.replaceFirst("ABCabc123abc", "[^A-Z0-9]+", "_")  = "ABC_123abc" 
StringUtils.replaceFirst("ABCabc123abc", "[^A-Z0-9]+", "")   = "ABC123abc" 
StringUtils.replaceFirst("Lorem ipsum  dolor   sit", "( +)([a-z]+)", "_$2")  = "Lorem_ipsum  dolor   sit"

[中]用给定替换替换替换与给定正则表达式匹配的文本字符串的第一个子字符串。
此方法是空安全的等效方法：
*文本。replaceFirst（regex，replacement）
*模式。编译（regex）。匹配器（文本）。替换优先（替换）
传递给此方法的null引用是no-op。
Pattern#DOTALL选项不会自动添加。使用DOTALL选项将"(?s)"前置到正则表达式。DOTALL在Perl中也称为单线模式。

StringUtils.replaceFirst(null, *, *)       = null 
StringUtils.replaceFirst("any", (String) null, *)   = "any" 
StringUtils.replaceFirst("any", *, null)   = "any" 
StringUtils.replaceFirst("", "", "zzz")    = "zzz" 
StringUtils.replaceFirst("", ".*", "zzz")  = "zzz" 
StringUtils.replaceFirst("", ".+", "zzz")  = "" 
StringUtils.replaceFirst("abc", "", "ZZ")  = "ZZabc" 
StringUtils.replaceFirst("<__>\n<__>", "<.*>", "z")      = "z\n<__>" 
StringUtils.replaceFirst("<__>\n<__>", "(?s)<.*>", "z")  = "z" 
StringUtils.replaceFirst("ABCabc123", "[a-z]", "_")          = "ABC_bc123" 
StringUtils.replaceFirst("ABCabc123abc", "[^A-Z0-9]+", "_")  = "ABC_123abc" 
StringUtils.replaceFirst("ABCabc123abc", "[^A-Z0-9]+", "")   = "ABC123abc" 
StringUtils.replaceFirst("Lorem ipsum  dolor   sit", "( +)([a-z]+)", "_$2")  = "Lorem_ipsum  dolor   sit"
