包路径：org.apache.commons.lang3.StringUtils
类名称：StringUtils
方法名：isAllBlank

StringUtils.isAllBlank介绍

[英]Checks if all of the CharSequences are empty (""), null or whitespace only.

Whitespace is defined by Character#isWhitespace(char).

StringUtils.isAllBlank(null)             = true 
StringUtils.isAllBlank(null, "foo")      = false 
StringUtils.isAllBlank(null, null)       = true 
StringUtils.isAllBlank("", "bar")        = false 
StringUtils.isAllBlank("bob", "")        = false 
StringUtils.isAllBlank("  bob  ", null)  = false 
StringUtils.isAllBlank(" ", "bar")       = false 
StringUtils.isAllBlank("foo", "bar")     = false 
StringUtils.isAllBlank(new String[] {})  = true

[中]检查所有字符序列是否为空（“”）、空或仅为空白。
空格由字符#isWhitespace（char）定义。

StringUtils.isAllBlank(null)             = true 
StringUtils.isAllBlank(null, "foo")      = false 
StringUtils.isAllBlank(null, null)       = true 
StringUtils.isAllBlank("", "bar")        = false 
StringUtils.isAllBlank("bob", "")        = false 
StringUtils.isAllBlank("  bob  ", null)  = false 
StringUtils.isAllBlank(" ", "bar")       = false 
StringUtils.isAllBlank("foo", "bar")     = false 
StringUtils.isAllBlank(new String[] {})  = true
