The spring-security-pac4j project is an easy and powerful security library for Spring Security web applications and web services (with or without Spring Boot). It supports authentication and authorization, but also advanced features like session fixation and CSRF protection. It's based on Java 8, Spring Security 5 and on the pac4j security engine v5. It's available under the Apache 2 license.

- A client represents an authentication mechanism. It performs the login process and returns a user profile. An indirect client is for web applications authentication while a direct client is for web services authentication:
▸ OAuth - SAML - CAS - OpenID Connect - HTTP - Google App Engine - Kerberos - LDAP - SQL - JWT - MongoDB - CouchDB - IP address - REST API
- An authorizer is meant to check authorizations on the authenticated user profile(s) or on the current web context:
▸ Roles/permissions - Anonymous/remember-me/(fully) authenticated - Profile type, attribute - CORS - CSRF - Security headers - IP address, HTTP method
-
A matcher defines whether the
SecurityFiltermust be applied and can be used for additional web processing -
The
SecurityFilterprotects an url by checking that the user is authenticated and that the authorizations are valid, according to the clients and authorizers configuration. If the user is not authenticated, it performs authentication for direct clients or starts the login process for indirect clients -
The
CallbackFilterfinishes the login process for an indirect client -
The
LogoutFilterlogs out the user from the application and triggers the logout at the identity provider level -
The
Pac4jEntryPointhandles when the user is not authenticated -
The
JEEContextand theProfileManagercomponents can be injected (for a Spring Boot/MVC webapp and using thespring-webmvc-pac4jlibrary) -
The
@RequireAnyRoleand@RequireAllRolesannotations check the user roles (for a Spring Boot/MVC webapp and using thespring-webmvc-pac4jlibrary).
Usage
1) Add the required dependencies
2) Define:
- the security configuration
- the callback configuration, only for web applications
- the logout configuration
3) Apply security
4) Get the authenticated user profiles
Demos
The demo webapps for Spring Security without Spring Boot: spring-security-pac4j-demo or with Spring Boot: spring-security-pac4j-boot-demo are available for tests and implement many authentication mechanisms: Facebook, Twitter, form, basic auth, CAS, SAML, OpenID Connect, JWT...
