Liu Yan,
To easily override the Tacos AjaxDirect service, simply add the following to
your hivemodule.xml:
<implementation service-id="tacos.AjaxDirect">
Implementation of IEngineService that handles various forms of
ajax requests. Should eventually replace IPartialService.
<invoke-factory>
<construct class="net.sf.tacos.ajax.impl.AjaxDirectServiceImpl"
autowire-services="false">
<set-object property="responseRenderer"
value="infrastructure:responseRenderer"/>
<set-object property="request" value="infrastructure:request"/>
<set-object property="linkFactory"
value="service:tapestry.url.LinkFactory"/>
<set-object property="webResponse"
value="infrastructure:response"/>
<set-object property="ajaxRequest"
value="service:tacos.AjaxWebRequest" />
<set-object property="delegateFactory"
value="service:tacos.ajax.ResponseDelegateFactory" />
<set-object property="requestCycle"
value="infrastructure:requestCycle"/>
<set-object property="exceptionPresenter"
value="service:tacos.AjaxExceptionPresenter"/>
<set-object property="staleSessionExceptionPresenter"
value="service:tacos.AjaxStaleSessionExceptionPresenter"/>
</construct>
</invoke-factory>
<!-- <interceptor service-id="hivemind.LoggingInterceptor"/> -->
</implementation>
I can't really help you on the Spring integration problem since I don't use
Hivemind to access my Spring application context. Sorry.
