java design patterns used in AEM

[srikanthg212933]

Hi Folks,

I am trying to explore more on java design patterns(e.g: Factory design pattern, Singleton design pattern or etc).So As an AEM developer I have question which design pattern we mostly use in AEM related use cases(e.g: sling models with services or web services call through sling Servlet...etc) and which could be the best fit to design most of our general AEM use cases.

Let me know if there is reference I can look at it. please enlighten.

Hi @srikanthg212933 ,

Some of the OSGI Patterns are listed here with references and sample examples

Hi @srikanthg212933,

We can use any design patterns that we like as OSGi makes CQ5 very modular, so we are free to use whatever suits our needs.Since AEM is built using OSGI, many of the design patterns for OSGI are valid.

Some of these design patterns are Singleton (Service), Adapter Service, Resource Adapter Service, and Whiteboard. Reference: https://felix.apache.org/documentation/subprojects/apache-felix-dependency-manager/guides/design-pat...

Thanks!!

This is good question or thread ...

Want to hear more on that ..

My views :

Singleton desgin pattern can be used in aem as well like if you want to do storing or acching any thing in object 

Any how Services in AEM is singletonclasses only .

Factory Desgin pattern --> Any use case where we can use this in AEM Prespective ?
