I have a list as follows:
ArrayList<DiameterMessageHandler> handlers = new ArrayList<>();
handlers.add(new AARHandler());
handlers.add(new CERHandler());
handlers.add(new PPAHandler());
handlers.add(new STRHandler());
handlers.add(new DWRHandler());
I am wondering how to create a spring bean that takes handlers as one of its arguments, i.e. is it possible to do this in the applicationContext.xml - Do I have to create separate beans for the list and each of the handlers(AARHandler etc) first? Here is my applicationContext.xml
<bean id="DiameterClient" class="com.rory.ptspsim.diameterclient.DiameterClient" scope="singleton" init-method="start">
<constructor-arg type="java.lang.String" index="0"><value>${pcca.host}</value></constructor-arg>
<constructor-arg index="1">WHAT GOES HERE?</constructor-arg>
</bean>
Probably you want all these handlers be Spring beans too. This is the configuration:
<bean id="DiameterClient" class="com.rory.ptspsim.diameterclient.DiameterClient" init-method="start">
<constructor-arg value="${pcca.host}" />
<constructor-arg>
<list>
<ref bean="aarHandler" />
...
</list>
</constructor-arg>
</bean>
<bean id="aarHandler" class="com.rory.ptspsim.diameterclient.AARHandler" />
