Lỗi do bản spring-boot đang dùng (2.7.0) và springfox 3.0.

Giải pháp:

Thêm config trong file application.yml

                
spring:
	mvc:
		pathmatch:
			matching-strategy: ant_path_matcher
                
        

và thêm bean WebMvcEndpointHandlerMapping

                        
	@Configuration
	public class WebMvcEndpointHandler {
