The spring-webmvc-pac4j project is an easy and powerful security library for Spring Web MVC / Spring Boot web applications and web services. It supports authentication and authorization, but also logout and advanced features like session fixation and CSRF protection. It's based on Java 8, Spring Web MVC 5 and on the pac4j security engine v3. It's available under the Apache 2 license.

Main concepts and components:

1. A client represents an authentication mechanism. It performs the login process and returns a user profile. An indirect client is for web application authentication while a direct client is for web services authentication:

▸ OAuth - SAML - CAS - OpenID Connect - HTTP - OpenID - Google App Engine - LDAP - SQL - JWT - MongoDB - CouchDB - Kerberos - IP address - Kerberos (SPNEGO) - REST API

2. 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

3. The SecurityInterceptor protects 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

4. The CallbackController finishes the login process for an indirect client

5. The LogoutController logs out the user from the application and triggers the logout at the identity provider level

6. The J2EContext and the ProfileManager components can be injected

7. The @RequireAnyRole and @RequireAllRoles annotations check the user roles.

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 Web MVC without Spring Boot: spring-webmvc-pac4j-demo or with Spring Boot: spring-webmvc-pac4j-boot-demo are available for tests and implement many authentication mechanisms: Facebook, Twitter, form, basic auth, CAS, SAML, OpenID Connect, JWT...
