Closed 3 years ago.
I am currently trying to move a java EE 8 project running on wildfly to the latest spring boot.
For this i will need primefaces, primefaces-extensions and omnifaces cause of it's
components i am already using and also designed (buyed) theme.
Starting with the latest spring boot in combination with joinfaces i currently try to
define the welcome page or redirect to the index.xhtml page
but anything i tried failed.
Here is my current sources:

So what's needed here to set the welcome-page for a jsf application right ?
When i directly called
http://localhost/index.xhtml
the primefaces page will be rendered right,
but when i enter
http://localhost/
no redirect to the index.xhtml will be made
and i currently found nothing which is working as a "redirect" ...

Answer 1

I think i currently found the solution :
So i post it for all others which are start using spring boot and primefaces together:
Adding this dependency will fix my problem with the welcome page as xhtml :
<!-- Add spring boot web needed for navigation -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
Then i can use the following class file to set my welcome-page:
/src/main/java/com/test/navigation/WelcomePageRedirect.java
#Configuration
public class WelcomePageRedirect implements WebMvcConfigurer {
#Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/")
.setViewName("forward:/index.xhtml");
registry.setOrder(Ordered.HIGHEST_PRECEDENCE);
}
}
Now the following technologies are working together:
Java 8 (And also Java 11 !)
Primefaces 7.0.11 + Primefaces Extensions
Omnifaces 3.4.1
Latest FontAwesome 5.12.0 in combination with Primefaces "old" FontAwesome
Spring Boot 2.2.4
JoinFaces 4.1.4
MyFaces 2.3
