        <div class="comment-block" style="background-color:#edf5ff;border:1px solid #dddddd;color:#000000;padding:12px;"><p>Observation:</p>

<p>The AbstractServiceableComponent and all derived classes are identifiable.  Further the name is usually set via a constructor parameter.<br/>
This is used for logging, but the passing of the name from Spring is usually cumbersome (the name is taken from the Strategy which is used to summon the  Component from the Application context.  So in the bean:</p>

<p> &lt;bean id="shibboleth.AttributeResolverService" class="net.shibboleth.ext.spring.service.ReloadableSpringService" <br/>
        depends-on="shibboleth.VelocityEngine"<br/>
        p:serviceConfigurations-ref="shibboleth.AttributeResolverResources"<br/>
        p:failFast="%</p>
{idp.service.attribute.resolver.failFast:false}
<p>"<br/>
        p:reloadCheckDelay="%</p>
{idp.service.attribute.resolver.checkInterval:0}
<p>"<br/>
        p:reloadTaskTimer="shibboleth.TaskTimer"&gt;<br/>
        &lt;constructor-arg name="claz"<br/>
            value="net.shibboleth.idp.attribute.resolver.AttributeResolver" /&gt;<br/>
        &lt;constructor-arg name="strategy"&gt;<br/>
            &lt;bean class="net.shibboleth.idp.attribute.resolver.spring.AttributeResolverServiceStrategy"<br/>
                p:id="ShibbolethAttributeResolver"/&gt;<br/>
        &lt;/constructor-arg&gt;<br/>
    &lt;/bean&gt;</p>

<p>The ID for the net.shibboleth.idp.attribute.resolver.spring.AttributeResolverServiceStrategy is used as the ID of the component.</p>

<p>Cumbersome and implicit.  </p>
<ul class="alternate" type="square">
        <li>Do we need these ServiceableComponents to be identified (usually there will only be one of each type per implementation?</li>
        <li>If so is there a better way to inject the name?</li>
</ul>


<p>I think the answer to the second is "possibly", by stopping the strategy being Identifiable and being more explicit about the name (so the next result in the segment abpove would be that p:id="ShibbolethAttributeResolver" would become p:componentId="ShibbolethAttributeResolver"</p>

<p>I suggest we answer the former in the next team meet.</p>
