Modules Communication
(从 Liferay modules communication 进行重定向)
The goal of this wiki article is to clarify the communication channels between portal and plugins classes.
In Liferay we have the following packages/entities:
- portal-service
- portal-kernel
- portal-impl
- plugins
The way they can interact and communicate is the following:
- portal-kernel can be called by the rest of entities (portal-service, portal-impl and plugins)
- portal-service can be called by portal-impl and plugins
- plugins can be called by other plugins using CLP communication (see this wiki article: CLP plugins communication)
Note: you may call plugins' services from the portal-impl using CLP too, but this is not a recommended way to work.
Here you have a diagram to make it clearer:
IMPORTANT UPDATE: This has recently changed for the current Liferay version - 6.0.2. portal-service and portal-kernel have been merged, so that it's much easier now to develop. See http://issues.liferay.com/browse/LPS-9370 for further information
