Following all previous steps we always configured JSF and Spring. In case we use third party library like Primefaces you will have to configure resources required by Primefaces manually in Spring Security xml.

Extending example at if we had Primefaces lib in our project we will have to add below configuration to jsfspring-sec-security-config.xml

<sec:intercept-url pattern="/javax.faces.resource/**" access="permitAll"/>

The resultant code will look like below:

jsfspring-sec-security-config.xml

No other configuration change is required to make Primefaces work with Spring Security
