spring 用户通过交互界面登录成功事件源码分析

版本

spring-security-web:5.6.7

源码

用户通过前端交互界面登录成功触发此事件

org.springframework.security.authentication.event.InteractiveAuthenticationSuccessEvent

事件触发过程

• 用户名密码认证过滤器
  org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter

public class UsernamePasswordAuthenticationFilter extends AbstractAuthenticationProcessingFilter 

• 认证处理过滤器
  org.springframework.security.web.authentication.AbstractAuthenticationProcessingFilter

private void doFilter(HttpServletRequest request, HttpServletResponse response, FilterChain chain)
	throws IOException, ServletException {
	if (!requiresAuthentication(request, response)) {
		chain.doFilter(request, response);
		return;
	}
	try {
		// 尝试对请求进行认证
		Authentication authenticationResult = attemptAuthentication(request, response);
		if (authenticationResult == null) {
			return;
		}
		this.sessionStrategy.onAuthentication(authenticationResult, request, response);
		// 认证成功
		if (this.continueChainBeforeSuccessfulAuthentication) {
			chain.doFilter(request, response);
		}
		successfulAuthentication(request, response, chain, authenticationResult);
	}
	catch (InternalAuthenticationServiceException failed) {
		this.logger.error("An internal error occurred while trying to authenticate the user.", failed);
		unsuccessfulAuthentication(request, response, failed);
	}
	catch (AuthenticationException ex) {
		// Authentication failed
		unsuccessfulAuthentication(request, response, ex);
	}
}
// 默认的认证成功处理行为
// 1. 将认证对象设置到安全上下文
// 2. 通知RememberMe服务
// 3. 发布交互认证成功事件
// 4. 执行成功处理器
