java - 在 spring security + spring boot 中禁用同一用户的多个登录

Question

我有以下 Spring 配置:-

static SessionRegistry SR;
@Override
protected void configure(HttpSecurity http) throws Exception {
    http
    .authorizeRequests()
    .antMatchers("/", "/forgotPwd", "/resetPwd").permitAll()
    .anyRequest().authenticated().and().formLogin().loginPage("/login")
    .defaultSuccessUrl("/home").failureUrl("/login?error").permitAll()
    .successHandler(authenticationSuccessHandler) // autowired or defined below
    .and().logout()
    .logoutRequestMatcher(new AntPathRequestMatcher("/logout"))
    .logoutSuccessHandler(myLogoutSuccessHandler)
    .permitAll()
    .and().sessionManagement()
    .maximumSessions(1)
    .maxSessionsPreventsLogin(true)
    .sessionRegistry(SR);
    }
    @Bean
    public ServletListenerRegistrationBean<HttpSessionEventPublisher> httpSessionEventPublisher() {
    return new ServletListenerRegistrationBean<HttpSessionEventPublisher>(new HttpSessionEventPublisher());
  }

我期待 sessionManagement().maximumSessions(1) 禁用同一用户的多次登录。它正在工作，但首先用户注销应用程序，所以我尝试在另一个浏览器中登录，但它显示This account is already used by someone。

请您告诉我哪里出了问题。

Answer 1

删除您的httpSessionEventPublisher 和SessionRegistry

试试这个配置:

@Override
protected void configure(HttpSecurity http) throws Exception {
  http.authorizeRequests()
    .antMatchers("/", "/forgotPwd", "/resetPwd").permitAll()
    .anyRequest().authenticated()
    .and()
      .formLogin().loginPage("/login").defaultSuccessUrl("/home").failureUrl("/login?error").permitAll()
    .and()
      .sessionManagement()
      .maximumSessions(1);
}

您可以在application.properties

中设置 session 超时

server.session.timeout= # Session timeout in seconds.
