官网推荐办法：

@SpringBootApplication
public class SwaggerBootstrapUiDemoApplication  implements WebMvcConfigurer{

	@Override
	public void addResourceHandlers(ResourceHandlerRegistry registry) {
		registry.addResourceHandler("doc.html").addResourceLocations("classpath:/META-INF/resources/");
		registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
	}
}

或者

@SpringBootApplication
public class SwaggerBootstrapUiDemoApplication  implements WebMvcConfigurer{

	@Override
	public void addResourceHandlers(ResourceHandlerRegistry registry) {
		registry.addResourceHandler("doc.html").addResourceLocations("classpath*:/META-INF/resources/");
		registry.addResourceHandler("/webjars/**").addResourceLocations("classpath*:/META-INF/resources/webjars/");
	}
}

如果还没有用，看看你是不是有这个配置

@Configuration
@EnableWebMvc
public class CoreConfig implements WebMvcConfigurer {
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry
                .addMapping("/**")
                .allowedOriginPatterns("*")
                .allowedMethods("GET","HEAD","POST","PUT","DELETE","OPTIONS")
                .allowCredentials(true)
                .maxAge(3600)
                .allowedHeaders("*");
    }
    }
