Question

我正在使用Spring开发一个网站，我使用Spring Security进行身份验证。我遇到了一个我无法解决的问题：

<div sec:authorize="!isAuthenticated()" id="login">
    SHOW IF NOT AUTHENTICATED
</div>
<div sec:authorize="isAuthenticated()">
    Hi <span th:text="${session.user.email}"></span>
</div>

当会话被破坏时，例如通过WebSecurityConfigurerAdapter中的更改，显示第二个div导致内部服务器错误，因为session.user对象为null。

如何让用户＆＃34;未经身份验证＆＃34;当他的会议被摧毁？

编辑：SecurityConfig

@Override
    protected void configure(HttpSecurity http) throws Exception {

        http.sessionManagement()
        .sessionCreationPolicy(SessionCreationPolicy.ALWAYS)
        .sessionAuthenticationErrorUrl("/login?error")
        .maximumSessions(1)
        .maxSessionsPreventsLogin(false)
        .expiredUrl("/login?expired")
        .and()
        .sessionFixation().newSession();

        http.authorizeRequests()
        .antMatchers("/css/**", "/img/**", "/fonts/**", "/js/**", "/", "/home", "/prizes", "/login").permitAll()
        .anyRequest().authenticated()
        .and()
        .formLogin().loginPage("/login").loginProcessingUrl("/dologin")
        .usernameParameter("username").passwordParameter("password")
        .defaultSuccessUrl("/loginsuccessful").failureUrl("/login?invalid").permitAll()
        .and()
        .logout()
        .logoutRequestMatcher(new AntPathRequestMatcher("/logout")).logoutSuccessUrl("/")
        .permitAll();
    }

Answer 1

好的，我无法使用isAuthenticated（），所以我通过在preHandle（）方法（拦截器）中手动检查会话中的每个用户对象来修复它

Spring Security - 用户在会话销毁时保持身份验证
