Package com.onec.auth

Class CsrfCookieFilter

java.lang.Object

org.springframework.web.filter.GenericFilterBean

org.springframework.web.filter.OncePerRequestFilter

com.onec.auth.CsrfCookieFilter

All Implemented Interfaces:

jakarta.servlet.Filter, org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanNameAware, org.springframework.beans.factory.DisposableBean, org.springframework.beans.factory.InitializingBean, org.springframework.context.EnvironmentAware, org.springframework.core.env.EnvironmentCapable, org.springframework.web.context.ServletContextAware

public class CsrfCookieFilter
extends org.springframework.web.filter.OncePerRequestFilter

Materializes the deferred CSRF token on every request so the XSRF-TOKEN cookie is present after the first response to a fresh client. Without this filter the cookie is only written when something downstream reads the token.

Public so applications that wire their own SecurityFilterChain can reuse it without copy-pasting (issue #30).
