Original
spring-security-pac4jis the Spring Security integration of pac4j, the security engine for Java. If it is useful to you, please ⭐ star pac4j on GitHub: it helps other developers discover it!
The spring-security-pac4j project is a bridge from pac4j to Spring Security (reactive) to push the pac4j security context into the Spring Security security (reactive) context.
It's based on the pac4j security engine. It's available under the Apache 2 license.
| spring-security-pac4j | JDK | pac4j | Spring security | Operating philosophy | Usage of Lombok | Status |
|---|---|---|---|---|---|---|
| version >= 10.1 | 17 | v6 | v6 or v7 | Bridge only | Yes | Production ready |
| version 10.0.x | 17 | v6 | v6 | Bridge only | Yes | Production ready |
| version >= 9 | 17 | v5 | v6 | Bridge only | No | Production ready |
| version >= 8 | 11 | v5 | v5 | Standalone security library | No | Production ready |
| version >= 6 | 11 | v5 | v5 | Standalone security library | No | Production ready |
| version >= 5 | 8 | v4 | v5 | Standalone security library | No | Production ready |
Since version 8 (working as a bridge only), it must be used with a pac4j security library:
- the jakartaee-pac4j (Spring 6) or javaee-pac4j (Spring 5) implementation (which has similar filters as
spring-security-pac4jversion <= 7.x) - if you use Spring MVC, the spring-webmvc-pac4j implementation version >= 7 (Spring 6) or version < 7 (Spring 5)
- if you use Spring Webflux, the spring-webflux-pac4j implementation version >= 2 (Spring 6) or version < 2 (Spring 5)
While it is always better to directly use a pac4j security library alone, this bridge can be used to keep legacy software and avoid full migration.
Usage
1) Add the required dependencies
2) The bridge is automatically installed
3) Install, configure and use the pac4j security library
You must refer to the documentation of the pac4j security library you use: jakartaee-pac4j or spring-webmvc-pac4j or spring-webflux-pac4j.
