java - Freemarker 全局变量值被附加两次

Question

我正在为全局变量分配一个值，但是当我使用它时，我会得到它两次#

<#global "base"="abc/xyz"></global>

当我使用 ${base} 时，我得到 abc/xyz/abc/xyz。

Answer 1

如果您检查global docs您的语法错误，选项是:

<#global name=value> or

<#global name1=value1 name2=value2 ...nameN=valueN> or

<#global name> capture this < /#global>

最简单的选择是

<#global base="abc/xyz">

还要确保您使用全局变量:

${.globals.abc}

For example, with <#global x = 1> you create a variable that isvisible as x in all namespaces, unless another variable called x hidesit (for example a variable what you have created as <#assign x = 2>).In this case, you can use special variable globals, like ${.globals.x}
