一. meta注入
<meta key="page.size" value="15"/> 
<inject property="pageSize" type="meta" object="page.size"/>
等同于：this.getEngine().getInfrastructure().getApplicationPropertySource().getPropertyValue("page.size")

二. object注入
<inject property="assetFactory" object="infrastructure:assetFactory"/>

<inject property="webRequest" object="infrastructure:request"/>
<inject property="cookieSource" object="infrastructure:cookieSource"/>
<inject property="pageService" object="engine-service:page"/>

四. script注入
<inject property="script" type="script" object="Palette.script"/>

this.getRequestCycle().getInfrastructure().getScriptSource().getScript(s);

<inject name="registration" type="state" object="registration-data"/>
等同于：
this.getEngine().getInfrastructure().getApplicationStateManager().get("registration-data");
