Hook - global. startup. events

[Jiri Mecner，修改在11 年前。]

Hi,

i have tryed use custom global.startup.events in my hook. I have followed book Liferay Portal Systems Development Second Edition. My hook consist of:

liferay-hook.xml

<!--?xml version="1.0"?-->


<hook>
	<portal-properties>portal.properties</portal-properties> 
</hook>

portal.properties

global.startup.events=com.liferay.sandbox.SandboxInitializationAction

but my action is not executed on server startup so i decided to debug code. At time when MainServlet calls processGlobalStartupEvents() global.startup.events = com.liferay.portal.events.GlobalStartupAction and only GlobalStartupAction is executed. Ok, then i decided to debug HookHotDeployListener mabe event will be executed there. At the first look global.startup.events is not present in SUPPORTED_PROPERTIES. When i go throught HookHotDeployListener i havent find any global.startup.events hanler.

Can anyone tell me what I missed?

You can use

application.startup.events instead of global.startup.events

if you need your custom event to be started when your hook applicaton is deployed.

One thing to note for this though is that in a multi-tenant environment (where you are using portal instances) the hook will run for EVERY instance when you use the application one. If you use the global one, then it will only run once. Unfortunately, I don't beleive that the global events are "hookable". I think y ou have to configure those in your portal-ext (or derivative) and make sure that the class is part of the classpath.

Alternatively, you could scope your hook to only run for the default instance using a little additional logic in the hook itself.

Correct - global.startup.events is not hookable. The DTD says so (it's quite well commented). +1
