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

StringUtils.removeStart介绍

[英]Removes a substring only if it is at the beginning of a source string, otherwise returns the source string.

A null source string will return null. An empty ("") source string will return the empty string. A null search string will return the source string.

StringUtils.removeStart(null, *)      = null 
StringUtils.removeStart("", *)        = "" 
StringUtils.removeStart(*, null)      =  
StringUtils.removeStart("www.domain.com", "www.")   = "domain.com" 
StringUtils.removeStart("domain.com", "www.")       = "domain.com" 
StringUtils.removeStart("www.domain.com", "domain") = "www.domain.com" 
StringUtils.removeStart("abc", "")    = "abc"

[中]仅当子字符串位于源字符串的开头时才删除该子字符串，否则返回源字符串。
空源字符串将返回空值。空（“”）源字符串将返回空字符串。空搜索字符串将返回源字符串。

StringUtils.removeStart(null, *)      = null 
StringUtils.removeStart("", *)        = "" 
StringUtils.removeStart(*, null)      =  
StringUtils.removeStart("www.domain.com", "www.")   = "domain.com" 
StringUtils.removeStart("domain.com", "www.")       = "domain.com" 
StringUtils.removeStart("www.domain.com", "domain") = "www.domain.com" 
StringUtils.removeStart("abc", "")    = "abc"
