RequestContextHolder.getRequestAttributes() null - Spring Se

Question

实现 spring 安全性(基本表单身份验证(后，我无法使用 RequestContextHolder.getRequestAttributes() 获取当前请求，这在以前工作正常。

问题是 RequestContextHolder.getRequestAttributes(( 为空，我需要从登录请求中获取一个额外的参数(租户 ID(才能选择正确的数据库。

这是我的代码：

安全

@EnableWebSecurity
public class Security extends WebSecurityConfigurerAdapter {
    @Autowired
    private MyUserDetailsService myUserDetailsService;
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests()
                .antMatchers("/assets/**")
                    .permitAll()
                .anyRequest().authenticated()
                    .and()
                .formLogin()
                    .loginPage("/dashboard/login")
                    .defaultSuccessUrl("/dashboard/home")
                    .permitAll()
                    .and()
                .logout()
                    .permitAll();
    }
    @Override
    protected void configure(AuthenticationManagerBuilder auth)
            throws Exception {
        auth.authenticationProvider(authenticationProvider());
    }
    @Bean
    public DaoAuthenticationProvider authenticationProvider() {
        DaoAuthenticationProvider authProvider
                = new DaoAuthenticationProvider();
        authProvider.setUserDetailsService(myUserDetailsService);
        authProvider.setPasswordEncoder(passwordEncoder());
        return authProvider;
    }

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder(11);
    }
}

CurrentTenantIdentifierResolverImpl

public class CurrentTenantIdentifierResolverImpl implements CurrentTenantIdentifierResolver {
    Logger log = LogManager.getLogger(CurrentTenantIdentifierResolverImpl.class);

    @Override
    public String resolveCurrentTenantIdentifier() {
        ServletRequestAttributes attr = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpSession session = attr.getRequest().getSession(false); // true == allow create
        if (session != null) {
            String tenant = (String) session.getAttribute("tenant");
            log.trace("Tenant default resolved in session is: " + tenant);
            if (tenant != null) {
                return tenant;
            }
        }
        String request = attr.getRequest().getRequestURI();
        String tenant = attr.getRequest().getParameter("tenant");
        if (request.equals("/dashboard/login") && tenant != null) {
            return tenant;
        }
        //otherwise return default tenant
        log.trace("Tenant default not resolved in session");
        return null;
    }
    @Override
    public boolean validateExistingCurrentSessions() {
        return true;
    }
}

我不小心删除了一个至关重要的类。只需将其添加回即可解决问题。

@Configuration
@WebListener
public class MyRequestContextListener extends RequestContextListener {
}
