StringUtils.isAlphanumeric介绍

[英]Checks if the CharSequence contains only Unicode letters or digits.

null will return false. An empty CharSequence (length()=0) will return false.

StringUtils.isAlphanumeric(null)   = false 
StringUtils.isAlphanumeric("")     = false 
StringUtils.isAlphanumeric("  ")   = false 
StringUtils.isAlphanumeric("abc")  = true 
StringUtils.isAlphanumeric("ab c") = false 
StringUtils.isAlphanumeric("ab2c") = true 
StringUtils.isAlphanumeric("ab-c") = false
