FilterChainProxy不会在Spring Boot应用程序中自动装配

Question

我正在尝试按如下方式自动装配FilterChainProxy实例：

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    private FilterChainProxy filterChainProxy;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.addFilterAfter( new CustomSecurityFilter(), BasicAuthenticationFilter.class);
    }
}

我收到以下异常：

Sep 22 20:08:16 xxxxxx java[21355]: 2017-09-22 20:08:16.953  WARN 21355 --- [           main] ationConfigEmbeddedWebApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'securityConfig': Unsatisfied dependency expressed through field 'filterChainProxy'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.security.web.FilterChainProxy' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

我把FilterChainProxy实例放在哪个类中并不重要。 我不使用XML来配置我的应用程序，所有Spring配置都是基于注释的。 如何解决这个问题？
