如何在运行时修改Spring Security过滤器链？

public class CustomFilterChain extends AbstractSecurityInterceptor implements FilterInvocationSecurityMetadataSource {

    private FilterInvocationSecurityMetadataSource securityMetadataSource;
    private AccessDecisionManager accessDecisionManager;

    public CustomFilterChain(FilterInvocationSecurityMetadataSource securityMetadataSource, AccessDecisionManager accessDecisionManager) {
        this.securityMetadataSource = securityMetadataSource;
        this.accessDecisionManager = accessDecisionManager;
    }

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
        // 初始化操作
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        FilterInvocation fi = new FilterInvocation(request, response, chain);
        invoke(fi);
    }

    public void invoke(FilterInvocation fi) throws IOException, ServletException {
        // 进行权限验证等操作
        InterceptorStatusToken token = super.beforeInvocation(fi);
        try {
            fi.getChain().doFilter(fi.getRequest(), fi.getResponse());
        } finally {
            super.afterInvocation(token, null);
        }
    }

    @Override
    public void destroy() {
        // 销毁操作
    }

    @Override
    public Class<?> getSecureObjectClass() {
        return FilterInvocation.class;
    }

    @Override
    public SecurityMetadataSource obtainSecurityMetadataSource() {
        return this.securityMetadataSource;
    }

    @Override
    public void setAccessDecisionManager(AccessDecisionManager accessDecisionManager) {
        this.accessDecisionManager = accessDecisionManager;
    }

    @Override
    public AccessDecisionManager getAccessDecisionManager() {
        return this.accessDecisionManager;
    }
}

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private CustomFilterChain customFilterChain;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/public/**").permitAll()
                .anyRequest().authenticated()
                .and()
            .addFilterBefore(customFilterChain, FilterSecurityInterceptor.class);
    }
}
