JSF 2 converters and Spring services

Problem

I have a JavaServer Faces 2 converter (using @FacesConverter) and I need to access a Spring service. The converter is managed by JSF, and if I try to use @Service or autowire a Spring bean, I get a null pointer exception.

Solution

Access the Spring service using FacesContextUtils. For example:

@Override 
public Object getAsObject(FacesContext facesContext, UIComponent uiComponent, String s) { 
    // Your code here 
     
    if (personneService == null) { 
        personneService = (PersonneService) FacesContextUtils.getWebApplicationContext(facesContext) 
            .getBean("personneService"); 
    } 
     
    // Rest of your implementation 
} 

This approach allows you to access Spring-managed beans from within a JSF converter.
