速度变量(同时使用字符串和整数变量) [英] Velocity Variable(use together string and integer variables)

问题描述

如何在Velocity"中同时使用字符串和整数变量?

#set ($var1 = "exp"+1)

我尝试了几次，但我不能.

I tried a few times but I could not.

任何帮助将不胜感激.

推荐答案

如果您尝试进行连接，Velocity 不支持它，甚至不支持 2 个字符串.相反，您应该使用字符串插值.示例:

If you were trying to do concatenation, it's not supported by Velocity, not even for 2 Strings. Instead, you should use string interpolation. Example:

#set ($string = "exp")
#set ($number = 1)
#set ($interpolatedExample1 = "$string$number")
#set ($interpolatedExample2 = "${string}someStringLiteral$number")
