Estou tentando configurar o Swagger 2 para uma API do Spring Boot 3. Estou recebendo esta mensagem ao acessar a interface do Swagger: "No operations defined in spec!". Não estou obtendo nenhuma operação definida na minha classe de Controller.

SwaggerConfig:

package br.com.api.sise.fatweb.manter;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
            .select()
            .apis(RequestHandlerSelectors.basePackage("br.com.bradseg.sise.fatweb.manter.rest"))
            .paths(PathSelectors.any())
            .build();

    } 

}

Controller

package br.com.api.sise.fatweb.manter.rest;

import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;

@RestController
@Api(value = "Health")
@RequestMapping("/health")
public class HealthRest {

    @ApiOperation(value = "Mostra se a aplicação está funcionando")
    @GetMapping("/check")
    public ResponseEntity<String> check() {
        return new ResponseEntity<>("Aplicação operando com sucesso", HttpStatus.OK);
    }

} 

Main:

package br.com.api.sise.fatweb.manter;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.jms.annotation.EnableJms;

    @SpringBootApplication  
    @EnableJms
    @ComponentScan(basePackages = "br.com.bradseg.sise.fatweb.manter") 
    public class SiseSrvFatwebManterApplication {

        public static void main(String[] args) {
            SpringApplication.run(SiseSrvFatwebManterApplication.class, args);
        }

    }

pom.xml (não contém tudo, para economizar espaço):

spring.profiles.active=dev
server.servlet.context-path=/sise-srv-fatweb-manter

O JSON que é retornado para mim no caminho /api-docs informa que não tem nenhum caminho (paths): {"openapi":"3.0.1","info":{"title":"OpenAPI definition","version":"v0"},"servers":[{"url":"http://localhost:8081/sise-srv-fatweb-manter","description":"Generated server url"}],"paths":{},"components":{}}

Eu já pesquisei tanto sobre o assunto, mas sinceramente não sei mais o que fazer. Estou estressado com tudo isso. Desde já agradeço por qualquer ajuda.
