嵌套速度模板中的上下文合并

Question

I have following velocity template with name exception.vm :

<span class="classname">$s.getClassName().</span>

I include this in another template with name cause.vm :

#include("templates/exception.vm")
<span class="classname">$s.getCause()</span>

When I merge this with a context:

Template tm = VelocityUtil.getTemplate("templates/cause.htm");
Context c = new VelocityContext();
c.put("s", new RuntimeException());
StringWriter sw = new StringWriter(100);
tm.merge(c, sw);

The $s.getCause() gets interpreted properly but $s.getClassName() does not get interpreted and prints as a literal.

Why is this?

Answer 1

Use:

#parse("templates/exception.htm")

Instead of:

#include("templates/exception.vm")

#include includes the resource without interpreting it.
