注销

Spring Security 默认提供注销端点。登录后，您可以 GET /logout 查看默认注销确认页面，或者 POST /logout 启动注销。这将

  • 清除 ServerCsrfTokenRepository、ServerSecurityContextRepository 和

  • 重定向回登录页面

通常，您还希望在注销时使会话失效。要实现此目的，您可以将 WebSessionServerLogoutHandler 添加到您的注销配置中，如下所示

  • Java

  • Kotlin

@Bean
SecurityWebFilterChain http(ServerHttpSecurity http) throws Exception {
    DelegatingServerLogoutHandler logoutHandler = new DelegatingServerLogoutHandler(
            new SecurityContextServerLogoutHandler(), new WebSessionServerLogoutHandler()
    );

    http
        .authorizeExchange((exchange) -> exchange.anyExchange().authenticated())
        .logout((logout) -> logout.logoutHandler(logoutHandler));

    return http.build();
}
@Bean
fun http(http: ServerHttpSecurity): SecurityWebFilterChain {
    val customLogoutHandler = DelegatingServerLogoutHandler(
        SecurityContextServerLogoutHandler(), WebSessionServerLogoutHandler()
    )

    return http {
        authorizeExchange {
            authorize(anyExchange, authenticated)
        }
        logout {
            logoutHandler = customLogoutHandler
        }
    }
}
