Juiser (pronounced "juicer", a portmanteau of "java", "juice" and "user")
is a small Java library that automates token authentication during an HTTP request. After authentication, a simple
but clean User object will be available to your code to support user-specific logic and authorization decisions.
Currently Juiser supports the X-Forwarded-User header with either JSON or JWS
values. Juiser 1.0.0 release supports Spring Boot applications, with other application environments
(e.g. Servlet only) added in the future. If you'd like to help in this effort, please open a GitHub issue to start
collaborating!
Juiser has one purpose and one purpose only - to translate an authentication token
into an intuitive User object and make that User object available during a request.
You can use the User object during a request to perform security checks
(like user.isAuthenticated() or user.hasRole("admin")) and get information about the user (e.g. user.getName()),
etc, and this may be perfectly suitable for many applications.
However if you have any need of more powerful security controls, we recommend that you use Apache Shiro or Spring Security and configure these frameworks to delegate to Juiser as necessary so you have one cohesive security programming experience.
Juiser already has native support for Spring Security so you can still leverage all the security controls
Spring Security provides. You don't even need to use Juiser's User api at all if you don't want to - just use
standard Spring Security classes like UserDetails and you'll never know Juiser is 'in the mix' at all.
That said, even with this Spring Security support, we think you'll find that our User API is a really nice
enhancement on top of Spring Security and you'll probably want to use it in addition to everything else Spring Security
provides.
We don't yet have native support for Apache Shiro, but we'll integrate as soon as we can. Any community help in this area would be appreciated! Please open a GitHub issue or Pull Request to initiate discussion and we'll be happy to help guide you!
