java - Spring-Security:认证后调用方法

Question

我想跟踪用户何时登录我的应用程序。我有一些代码想在用户通过身份验证后立即执行。问题是，我不知道应该在哪里调用它。 spring-security 有办法在认证后调用方法吗？

Answer 1

可能对某人有用...在 Spring 3 的情况下，配置安全性:

<security:http use-expressions="true" auto-config="true">
    <security:intercept-url pattern="..."/>
    <security:form-login
            authentication-failure-handler-ref="authFailureHandler"
            authentication-success-handler-ref="authSuccessHandler"/>
    <security:logout success-handler-ref="logoutSuccessHandler"
            invalidate-session="true"/>
    <security:session-management session-fixation-protection="newSession"/>
</security:http>

<bean id="authFailureHandler" class="mine.AuthenticationFailureHandlerImpl"/>
<bean id="authSuccessHandler" class="mine.AuthenticationSuccessHandlerImpl"/>
<bean id="logoutSuccessHandler" class="mine.LogoutSuccessHandlerImpl"/>

并实现一个适当的类:

public class AuthenticationSuccessHandlerImpl implements AuthenticationSuccessHandler {

    @Override
    public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
        //do what you want with 
        response.getOutputStream().write("success".getBytes());
    }
}
