前言
本文章主要从spring security安全认证登录内部调用流程来流程分析登录过程。
一、登录时序图

spring security配置类配置token认证过滤器（JwtAuthenticationTokenFilter）、
认证失败处理类（AuthenticationEntryPointImpl）、退出处理类（LogoutSuccessHandlerImpl）
1-JwtAuthenticationTokenFilter：

2-AuthenticationEntryPointImpl:认证失败处理类 返回未授权

/**

*/
@Configuration
public class LogoutSuccessHandlerImpl implements LogoutSuccessHandler

@Autowired

*/
@Override
public void onLogoutSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication)
throws IOException, ServletException
{
LoginUser loginUser = tokenService.getLoginUser(request);
if (StringUtils.isNotNull(loginUser))
{
String userName = loginUser.getUsername();
// 删除用户缓存记录
tokenService.delLoginUser(loginUser.getToken());
// 记录用户退出日志
AsyncManager.me().execute(AsyncFactory.recordLogininfor(userName, Constants.LOGOUT, "退出成功"));
}
ServletUtils.renderString(response, JSON.toJSONString(AjaxResult.error(HttpStatus.SUCCESS, "退出成功")));
}
}
