Spring webSecurity.ignoring() 不会忽略自定义过滤器

我在 Spring 4 MVC + Security + Boot 项目中设置了一个自定义身份验证过滤器。过滤器很好地完成了它的工作，现在我想禁用某些 URI 的安全性（例如/api/**）。这是我的配置：

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter{
    @Override
    public void configure(WebSecurity webSecurity) throws Exception {
        webSecurity.ignoring().antMatchers("/api/**");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
       http.authorizeRequests()
                 .anyRequest().authenticated()
              .and()
                 .addFilterBefore(filter, BasicAuthenticationFilter.class);
    }
}

不幸的是，当我在下面调用资源时/api/...过滤器仍处于连锁状态。我已经添加println在我的过滤器中，每次调用时都会将其写入控制台。你知道我的配置有什么问题吗？

UPDATE

过滤代码：

@Component
public class EAccessAuthenticationFilter extends RequestHeaderAuthenticationFilter {

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        System.out.println("FILTER");
        if(SecurityContextHolder.getContext().getAuthentication() == null){
            //Do my authentication stuff
            PreAuthenticatedAuthenticationToken authentication = new PreAuthenticatedAuthenticationToken(user, credential, authorities);
            SecurityContextHolder.getContext().setAuthentication(authentication);
        }  
        super.doFilter(request, response, chain);
     }

    @Override
    @Autowired
    public void setAuthenticationManager(AuthenticationManager authenticationManager) {
        super.setAuthenticationManager(authenticationManager);
    }

}

删除 EAccess 身份验证过滤器类上的 @Component，如下所示：

@Override
protected void configure(HttpSecurity http) throws Exception {
   http.authorizeRequests()
             .anyRequest().authenticated()
          .and()
             .addFilterBefore(new EAccessAuthenticationFilter(), BasicAuthenticationFilter.class);
}
