Is there any way to break up struts-config.xml into multiple xml files?
I'd like to be able to logically group my form and action mappings in
separate files.
Yes, you can use any number of struts-config files; there is a
servlet init parameter which accepts a comma-separated list.
<param-name>config</param-name>
<param-value>
/WEB-INF/struts-config.xml,
/WEB-INF/admin/struts-config.xml,
/WEB-INF/approval/struts-config.xml,
...
</param-value>
We have become very comfortable with a structure like the above which
partitions the application into packages which are roughly analogous
to use cases, or small sets of use cases. the root struts-config.xml
holds things like plugin definitions and global exception handling,
then each sub-directoried file holds the related action mappings and
action forms for that package.
The same sub-directory also contains tiles-definition.xml,
validation.xml, and spring-config.xml files (we use Spring to inject
dependencies into our controllers). (Of course, you have to add the
pointers to these files manually in a few places; some kind of
autodiscovery would be nice, but it's not that much work...)
Then we have an analogously structured Java package naming for
controllers and related code:
foo.project.prefix.webui.admin.*
foo.project.prefix.webui.approval.*
and we strictly use action mapping paths that also match this pattern:
/admin/AdminHome.do
/admin/AdminSubtask.do
/approval/ApprovalHome.do
/approval/SubmitApproval.do
and more of the same for JSPs, etc. We find that it means that even
someone completely new to a project can zero in on an area of concern
extremely efficiently. I think it's one of the reasons that I don't
really see Struts as nearly as much "XML Hell" as some detractors do.
