以速度动态构造变量名 [英] construct variable names dynamically in velocity

问题描述

我想知道是否可以将变量的名称动态构造为速度.

I would like to know if it is possible to construct name of variable into velocity dynamically.

即假设我有 6 个变量到速度模板 [name1, name2, name3 .. name6] 我想输出它们.所以我正在寻找类似的东西:

i.e. lets say I've 6 variables into velocity template [name1, name2, name3 .. name6] I would like to output them. So I'm looking in something like:

#foreach ( $counter in [1..6] )
${name${counter}}
#end

有可能吗?

推荐答案

可以使用 #evaluate 指令:

It is possible using the #evaluate directive:

#evaluate ('$name1')

#set ($d = '$')
#foreach ($i in [1..6])
  #set ($varName = "${d}name${i}")
  #evaluate($varName)
#end
