我需要在会话超时后自动重定向到登录页面，或者至少显示会话已过期的警报。我尝试配置Spring Security，但它不起作用，调试器在超时后无法捕获LogoutSuccessHandlerService中的代码。也许我遗漏了一些东西，或者Spring Security的这种方法从一开始就是错误的？如果是这样的话，有人能提供这样的任务完整的工作示例吗？我使用的是Sping Boot 2.5.6，Spring Security，前端是html，javascript，JQuery和dataTable。下面是我的代码：
SecurityConfig.java

private final AppProperties appProperties;

@Autowired
private LogoutSuccessHandlerService logoutSuccessHandlerService;

@Override
public void configure(WebSecurity web) {
    web.ignoring()
            .antMatchers("/static/**")
            .antMatchers("/webjars/**")
            .antMatchers("/css/**")
            .antMatchers("/fonts/**")
            .antMatchers("/img/**")
            .antMatchers("/js/**")
            .antMatchers("/scripts/**")
    ;
}

@Override
protected void configure(HttpSecurity http) throws Exception {
    http
            .formLogin()
            .loginPage("/login")
            .permitAll()
            .defaultSuccessUrl("/", true)
            .failureUrl("/login?error=true")
            .loginProcessingUrl("/j_spring_security_check")
            .and()
            .authorizeRequests()
            .anyRequest().authenticated()
            .and()
            .logout()
            .invalidateHttpSession(true)
            .logoutSuccessHandler(logoutSuccessHandlerService)
            .logoutSuccessUrl("/login")
            .permitAll()
            .and()
            .csrf().disable();
}

@Override
public void configure(AuthenticationManagerBuilder auth) throws Exception {
    AppProperties.Security security = appProperties.getSecurity();

    auth.inMemoryAuthentication()
            .withUser(security.getUser())
            .password(passwordEncoder().encode(security.getPassword()))
            .roles(security.getRole());
}

@Bean
public PasswordEncoder passwordEncoder() {
    return new BCryptPasswordEncoder();
}

LogoutSuccessHandlerService.java 扩展了简单URL注销成功处理程序

@Override
public void onLogoutSuccess(HttpServletRequest request,
                            HttpServletResponse response,
                            Authentication authentication) throws IOException, ServletException {
    if (authentication != null) {

    }
    log.info("logout success");
    setDefaultTargetUrl("/login");

    super.onLogoutSuccess(request, response, authentication);
}
