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

StringUtils.trim介绍

[英]Removes control characters (char <= 32) from both ends of this String, handling null by returning null.

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

To trim your choice of characters, use the #strip(String,String) methods.

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

[中]从该字符串的两端删除控制字符（char<=32），通过返回null来处理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#strip（String）。
要修剪您选择的字符，请使用#strip（String，String）方法。

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