类名称：StringUtils
方法名：stripToNull

StringUtils.stripToNull介绍

[英]Strips whitespace from the start and end of a String returning null if the String is empty ("") after the strip.

This is similar to #trimToNull(String) but removes whitespace. Whitespace is defined by Character#isWhitespace(char).

StringUtils.stripToNull(null)     = null 
StringUtils.stripToNull("")       = null 
StringUtils.stripToNull("   ")    = null 
StringUtils.stripToNull("abc")    = "abc" 
StringUtils.stripToNull("  abc")  = "abc" 
StringUtils.stripToNull("abc  ")  = "abc" 
StringUtils.stripToNull(" abc ")  = "abc" 
StringUtils.stripToNull(" ab c ") = "ab c"

[中]从字符串的开头和结尾删除空格，如果字符串在删除后为空（“”），则返回null。
这类似于#trimToNull（字符串），但删除了空格。空格由字符#isWhitespace（char）定义。

StringUtils.stripToNull(null)     = null 
StringUtils.stripToNull("")       = null 
StringUtils.stripToNull("   ")    = null 
StringUtils.stripToNull("abc")    = "abc" 
StringUtils.stripToNull("  abc")  = "abc" 
StringUtils.stripToNull("abc  ")  = "abc" 
StringUtils.stripToNull(" abc ")  = "abc" 
StringUtils.stripToNull(" ab c ") = "ab c"
