Know Module And Component

The main reason for LIFERAY to move into module framework is,

• Creating small modules (Tightly coupled)
• Publish and consume other modules features (Inflexible)
• Working without static dependencies (Dynamic dependencies)

To use module framework,

You mainly need to understand below 3 concepts :

1. Modules
2. Components
3. Application Lifecycle 

Module:

Module is something which is group of Java classes, other optional resources, and a MANIFEST.MF file, packaged together as into a  single JAR file. Liferay 7 uses three modules/bundles.

Modules can have multiple components.

Component:

Component is nothing but implementation of interface like the way we were doing with *LocalServiceImpl class in older fashion. So here what you need to do is, you just will have to load components through annotations in implementation class.These loaded/declared components would be part of modules.

Here Lifecycle of modules and component will be handled through Liferay's OSGi based module framework.
