拦截器中无法注入Autowired

@Configuration
public class InterceptorConfig implements WebMvcConfigurer {
    @Bean
    public AuthorityInterceptor getUserInterceptor(){
        return new AuthorityInterceptor();
    }
    @Override
    public void addInterceptors(InterceptorRegistry registry) {

        registry.addInterceptor(getUserInterceptor()).addPathPatterns(
                "/**")
                .excludePathPatterns(
                        "/register/**"
                        , "/login/**"
                );
    }
}
