I've just checked in the command code to xwork. It allows you to do
this:
<action name="commandTest"
class="com.opensymphony.xwork.SimpleAction">
<param name="foo">123</param>
<result name="error" type="chain">
<param name="actionName">bar</param>
</result>
<interceptor-ref name="static-params"/>
<command name="myCommand" method="commandMethod">
<param name="bar">456</param>
<result name="success" type="chain">
<param name="actionName">foo</param>
</result>
<interceptor-ref name="logger"/>
</command>
</action>
The command here creates a new alias in the runtime configuration and
inherits properties from the enclosing action. It will also call the
supplied method. Actions are not required to supply a method, although
they can as well. If no method is supplied for an Action, it defaults to
calling action.execute(). For now Actions must still implement this
interface, although this can easily be removed and the object can be
cast to Action before calling execute().
This should be the last major change to configuration. The only other
thing I want to do, and I just thought of this while I was writing this,
is to make name optional on the Action and have it not create a runtime
ActionConfig for the action itself if there is no name, although you
could have several commands underneath the action which would be
configured.
I also refactored the names of the config classes.
Configuration -> ConfigurationProvider
ConfigurationFactory -> ConfigurationProviderFactory
DefaultConfiguration -> DefaultConfigurationProvider
SimpleConfiguration -> SimpleConfigurationProvider
I've also created 2 new classes in the ActionConfig class hierarchy to
support commands:
ActionCommand
^
|
ActionConfig
^
|
HierarchicalActionConfig
ActionCommand has:
methodName
Interceptors
Parameters
Results
resultParameters
ActionConfig adds:
Class clazz
TypeConverter
HierarchicalActionConfig adds:
Commands
ActionConfig is the runtime datastructure, the other 2 are used on the
programmatic side.
Ok, so go ahead and start making fun of my class naming, but you'd
better have some better ideas :-)
