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

StringUtils.trimToNull介绍

[英]Removes control characters (char <= 32) from both ends of this String returning null if the String is empty ("") after the trim or if it is null.

The String is trimmed using String#trim(). Trim removes start and end characters <= 32. To strip whitespace use #stripToNull(String).

StringUtils.trimToNull(null)          = null 
StringUtils.trimToNull("")            = null 
StringUtils.trimToNull("     ")       = null 
StringUtils.trimToNull("abc")         = "abc" 
StringUtils.trimToNull("    abc    ") = "abc"

[中]从该字符串的两端删除控制字符（char<=32），如果修剪后的字符串为空（“”）或为空，则返回null。
使用字符串#trim（）修剪字符串。Trim删除起始字符和结束字符<=32。要去除空白，请使用#stripToNull（字符串）。

StringUtils.trimToNull(null)          = null 
StringUtils.trimToNull("")            = null 
StringUtils.trimToNull("     ")       = null 
StringUtils.trimToNull("abc")         = "abc" 
StringUtils.trimToNull("    abc    ") = "abc"
