With this knowledge, we will learn how to implement authentication and authorization services for a simple web application.

Prior to access to the resource, interception determines whether or not the resource should be protected. Enter the Acegi Security framework, an open source security framework designed for Spring. In the afegi of web applications, security interception is done using a servlet filter – SecurityEnforcementFilter securit in combination with the FilterSecurityInterceptor.

Insufficient features and lack of portability of Servlet and EJB security standards initially drove interest in Acegi, which since the has evolved into a project with support for most of today’s authentication schemes.

The sole shipping implementation of this interface is the RoleVoterwhich grants access if the principal has been assigned the role. Please consult the reference documentation to learn more.

Therefore, security is often one of the most important aspects.

Pathway from ACEGI to Spring Security 2.0
