java – 未调用Spring Security过滤器

我在弹簧启动应用程序中配置了过滤器的代码.当我发出请求时,我的第二个过滤器是B,不会调用.

import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.builders.WebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.config.annotation.web.servlet.configuration.EnableWebMvcSecurity;

@Configuration
@EnableWebMvcSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter  {
    @Override
    public void configure(WebSecurity webSecurity) throws Exception {
        webSecurity.ignoring().antMatchers(HttpMethod.GET,"/health");
    }
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
        http.addFilterBefore(new A(),BasicAuthenticationFilter.class);
        http.addFilterAfter(new B(),new A().getClass());
    }
}

import org.springframework.web.filter.GenericFilterBean;
public class A extends GenericFilterBean {

    @Override
    public void doFilter(ServletRequest arg0,ServletResponse arg1,FilterChain arg2)
            throws IOException,ServletException {
        System.out.println("filter A");
    }
}

import org.springframework.web.filter.GenericFilterBean;
public class B extends GenericFilterBean {

    @Override
    public void doFilter(ServletRequest arg0,ServletException {
        System.out.println("filter B");         
    }
}

编辑：

 public class A extends GenericFilterBean {

        @Override
        public void doFilter(ServletRequest arg0,FilterChain arg2) throws IOException,ServletException {
             System.out.println("filter A Before");
             arg2.doFilter(arg0,arg1);
             System.out.println("filter A After");
        }
}
