将@Component添加到自定义Spring Security过滤器的含义是什么？

Question

我有一个自定义的Spring Security过滤器,扩展了GenericFilterBean.

为了进行自动依赖和bean创建,我添加了一个@Component注释.

在我的安全配置中,我也注册过滤器,如:

@Autowired
private RestAuthenticationFilter restAuthenticationFilter;

protected void configure(HttpSecurity http) throws Exception {
    // @formatter:off
    http
        .addFilterBefore(restAuthenticationFilter, LogoutFilter.class)

一切都运行良好,除了我的过滤器被调用两次......似乎Spring也自动将过滤器添加到标准过滤器.

这里最好的方法是什么？

UPDATE

@Dave这是你的意思吗？它似乎工作.

@Configuration
@ComponentScan
@EnableAutoConfiguration
public class Application extends WebMvcConfigurerAdapter {

    @Autowired
    private RestAuthenticationFilter restAuthenticationFilter;

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    @Bean
    public ApplicationSecurity applicationSecurity() {
        return new ApplicationSecurity();
    }

    @Bean
    public FilterRegistrationBean filterRegistrationBean() {
        FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();
        filterRegistrationBean.setEnabled(false);
        filterRegistrationBean.setFilter(restAuthenticationFilter);
        return filterRegistrationBean;
    }

    @Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
    protected static class ApplicationSecurity extends WebSecurityConfigurerAdapter {

        @Autowired
        private RestAuthenticationFilter restAuthenticationFilter;

        @Override
        protected void configure(HttpSecurity http) throws Exception {
            // @formatter:off
            http
                .addFilterBefore(restAuthenticationFilter, LogoutFilter.class)
                .authorizeRequests()
                    .anyRequest().authenticated()
                    .and()
                .csrf()
                    .disable()
                .exceptionHandling()
                    .authenticationEntryPoint(new Http403ForbiddenEntryPoint())
                    .and()
                .requestCache()
                    .requestCache(new NullRequestCache())
                    .and()
                .sessionManagement()
                    .sessionCreationPolicy(SessionCreationPolicy.STATELESS);
            // @formatter:on
        }
    }
}

您需要显式注册过滤器并使用FilterRegistrationBeanAPI 将其标记为"enabled = false" .然后Spring Security将在其链中使用它,但Boot也不会尝试注册它.
