Velocity中两个字符串的字典序比较
Lexicographic compare of two strings in Velocity
我在 Velocity 模板中有两个字符串变量。我想做一个词典比较。我试过这个:
#if ($string1 > $string2)
#set ($largest = $string1)
#else
#set ($largest = $string2)
#end
## (assume `$string1` and `$string2` are never Null)
所以,如果 $string1
包含字符串 "dog"
并且 $string2
包含字符串 "cat"
,那么 $largest
最终将包含字符串 "dog"
.
以上代码生成此消息:
Left side of '>=' operation is not a Number
如何进行我想要的比较?
你可以使用Java字符串的compareTo方法来比较字符串
The result is a positive integer if this String object lexicographically follows the argument string
#if ($string1.compareTo($string2) > 0)
#set ($largest = $string1)
#else
#set ($largest = $string2)
#end
