如何创建输出两个“#”的速度模板？ 行首的文字？
我需要创建一个速度文档，其中一些行前缀为“## Foo”，但由于 # 是速度指令命令，它对我不起作用。
我想要我的 输出 文档看起来像：
## Foo this
## Bar that
k1, v1
k2, v2
k3, v3
转义没有按照我的预期进行，显然，下面的内容不起作用，因为 # 没有转义）：
## Foo this
## Bar that
#foreach( $foo in $bar )
$foo.key, $foo.value
#end
## 行不工作。再次出现，正如预期的那样，但是，我的逃避尝试也不起作用。 逃避解决方案一：
\## Foo this
\## Bar that
#foreach( $foo in $bar )
$foo.key, $foo.value
#end
逃避解决方案二：
\#\# Foo this
\#\# Bar that
#foreach( $foo in $bar )
$foo.key, $foo.value
#end
甚至这个...
# set($msg = "##")
$msg Foo this
$msg Bar that
#foreach( $foo in $bar )
$foo.key, $foo.value
#end
最后一个真的让我感到困惑。
或者
I need to create a velocity document that has some lines prefixed with ¨## Foo", but since the # is the velocity directive command, it is not working for me.
What I want my output document to look like:
## Foo this
## Bar that
k1, v1
k2, v2
k3, v3
Escaping has not worked out how I expected. The below does not work, obviously, as the #s are un-escaped):
## Foo this
## Bar that
#foreach( $foo in $bar )
$foo.key, $foo.value
#end
The ## lines don't show up--again, as expected. But, my attempts at escaping do not work either. Escaping solution one:
\## Foo this
\## Bar that
#foreach( $foo in $bar )
$foo.key, $foo.value
#end
or this, escaping solution two:
\#\# Foo this
\#\# Bar that
#foreach( $foo in $bar )
$foo.key, $foo.value
#end
or even this...
# set($msg = "##")
$msg Foo this
$msg Bar that
#foreach( $foo in $bar )
$foo.key, $foo.value
#end
This last one really confused me.
Any ideas?

使用 Velocity 上下文：
Use the Velocity context:
如果您不想添加 org.apache.velocity.tools.generic。 EscapeTool 或与您的上下文类似，您可以使用第三次尝试的稍微修改的版本：
If you don't want to add org.apache.velocity.tools.generic.EscapeTool or similar to your context, you can use a slightly modified version of your third try:
叹息......单引号和双引号之间是有区别的。 这按预期工作：
打印出我想要的内容：
来自 Velocity用户指南：
（我仍然困惑于为什么 \#\# 不起作用。）
Sigh....There is a difference between single quote and double quotes. This works as expected:
Which prints out exactly what I wanted:
From the Velocity Users Guide:
(I'm still stumped as to why \#\# does not work.)
“##”是VTL中的单行注释分隔符，这可能是问题的开始。
"##" is the single line comment delimiter in VTL, which is probably the start of your problems.
