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

StringUtils.isNotBlank介绍

[英]Checks if a CharSequence is not empty (""), not null and not whitespace only.

Whitespace is defined by Character#isWhitespace(char).

StringUtils.isNotBlank(null)      = false 
StringUtils.isNotBlank("")        = false 
StringUtils.isNotBlank(" ")       = false 
StringUtils.isNotBlank("bob")     = true 
StringUtils.isNotBlank("  bob  ") = true

[中]检查CharSequence是否不为空（“”）、是否为null以及是否仅为空白。
空格由字符#isWhitespace（char）定义。

StringUtils.isNotBlank(null)      = false 
StringUtils.isNotBlank("")        = false 
StringUtils.isNotBlank(" ")       = false 
StringUtils.isNotBlank("bob")     = true 
StringUtils.isNotBlank("  bob  ") = true
