Hi,
I was wondering why there's no way to assign multiple parameters to
action mappings, and came with the following solution. Basically, the
idea is to have something like: "
<action path="/index" type="pl.wwtech.shared.struts.IndexAction">
<set-parameter name="test" value="value"/>
<forward name="default" path="page.index"/>
</action>
"
in struts.xml, then to be able to use it like:
" System.out.println(mapping.getParameter("test","default-value"));
System.out.println(mapping.getParameter("test"));
"
from Action subclass. Additionaly, getParameter returns value of the
same type (limited) as default value, so it is possible to have: " float
f = mapping.getParameter("test-float",0.0);
long l = mapping.getParameter("test-long",0);
"
It also implements a basic getAttribute / setAttribute scheme to allow
for "mapping-scope" runtime-only attributes. Of course it can easily be
modified (I volunteer if you want it) to support initialization from
xml. I needed something like that on numerous occasions so I included it
here.
I have attached some code based on 1.1b2 - please review it and let me
know if you want me to post the whole thing. I'm sure it's stable, we're
already using it in a number of production projects. To quickly find all
modified fragments search for "MMM" (case-sensitive). I'm not sure about
the configuration code - I don't use the Digester normally, I know it
works (heavily tested) but I'm not sure if it's the best (or most
recommended) way to implement this. There's no freeze-checks because
only name-value pairs are stored, so once added the parameters are
effectively immutable (by design). Also, comments are lacking because
the code is so basic they're not really needed. "//MMM" in various
places can (should) of course be removed - my team use triple m as a
kind of tag. Please let me know what you think - I need this (or
similar) capability in Struts, and I would be gratefull if you could
include it it nightlies or next beta. Greetings,
