How to integrate OmniFaces with Spring Boot

Question

I've found some tutorials about integrating JSF technology with Spring Boot, but it seems a rather involved work to get OmniFaces working with Spring Boot. Is it a good idea to integrate these two together at all?

I've got the latest omnifaces 1.x version working with JSF 2.2 in a Spring Boot project. I believe the real integration relates to make JSF work in Spring Boot (which is couple of steps), not omnifaces. The reason why I keep with the 1.x branch is that it fulfills my requirements and doesn't require CDI. – Apostles

@XtremeBiker: I didn't know that omnifaces 1.x version does not require CDI. Thanks. – Amrita

OmniFaces is provided via JoinFaces.

<dependency>
    <groupId>org.joinfaces</groupId>
    <artifactId>omnifaces-spring-boot-starter</artifactId>
    <version>5.x.x</version>
</dependency>

Or when you're still on Spring Boot 2.x:

<dependency>
    <groupId>org.joinfaces</groupId>
    <artifactId>omnifaces3-spring-boot-starter</artifactId>
    <version>4.x.x</version>
</dependency>

In case you're primarily intertested in OmniFaces @ViewScoped, then you really need @Named instead of @Component in order to fully utilize its powers. And in order to be able to inject existing Spring managed beans via @Autowired into those @Named beans without any additional fuzz, you might want to install a CDI extension as described in this blog Using OmniFaces CDI @ViewScoped with unload/destroy in a Spring Boot project.
