You know how callers to radio shows say "Hi, I'm a long time listener but
a first time caller and I love your show."? This is like that for me.
Anyway...
Has anyone already handled a situation where domain objects being acted
upon are identified by id number (or at least something where getClass()
can't work). Let's just suppose it's a good idea otherwise to pass in id
instead of some less opaque object since I can't necessarily control that
interface.
No? I'm imaging whipping up a new voter that is told per-method how to
grok the identifier (instead of looking for the first instance of some
class). I think it would be wired up like this:
<bean id="aclViewVoter"
class="not.yet.MapMethodParamaeterToInstanceIdVoter">
<!-- tells us which parameters are the userId s ...obviously we
could get the voters to share this instead of duplicating it-->
<property name="methodDefinitionSource">
<!-- the right hand side is a template for a
MessageFormat, which will evetually be format'ted with the method
parameters -->
<value>
com.domain.project.interface.addNoteForUser=com.domain.project.obj.User:{0}
com.domain.project.interface.getNotesForUser=com.domain.project.obj.User:{0}
</value>
</property>
<!-- as in the other voters -->
<property
name="processConfigAttribute"><value>SOME_ATTRIBUTE_THAT_IMPLIES_WE_SHOULD_CHECK_FOR_READ</value></property>
<property name="aclManager"><ref local="aclManager"/></property>
<property name="requirePermission">
<list>
<ref
local="net.sf.acegisecurity.acl.basic.SimpleAclEntry.READ"/>
</list>
</property>
</bean>
Does that make any sense? Thanks (in advance) for your attention,
