1.引入依赖

    
    
      io.springfox
      springfox-boot-starter
      3.0.0
    

    
      org.springframework.boot
      spring-boot-starter-web
      2.6.15
    


2.配置类

import org.springframework.boot.actuate.autoconfigure.endpoint.web.WebEndpointProperties;
import org.springframework.boot.actuate.autoconfigure.web.server.ManagementPortType;
import org.springframework.boot.actuate.endpoint.ExposableEndpoint;
import org.springframework.boot.actuate.endpoint.web.*;
import org.springframework.boot.actuate.endpoint.web.annotation.ControllerEndpointsSupplier;

/**

@Configuration
@EnableOpenApi
public class Swagger3Config {


    private String basePackage = "com.xxx.xxx.controller";


    @Bean
    public Docket createRestApi() {

        return new Docket(DocumentationType.OAS_30)
                .groupName("api")
                .enable(true) // .enable(!"prod".equals(active))
                .apiInfo(apiInfo())
                .select()

                .apis(RequestHandlerSelectors.withClassAnnotation(Api.class))  // 基于注解
                .apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class)) // 基于注解
                .paths(PathSelectors.any())
                .build();
    }


    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("API 接口文档")
                .description("Restful API 接口文档")
                .version("1.0")
                .contact(new Contact("联系人姓名","联系人url","联系人email"))
                .termsOfServiceUrl("服务条款URL")
                .license("xxx License Version 1.0")
                .licenseUrl("http://www.xxx.xxx/licenses/LICENSE-1.0")
                .build();
    }




    /**
     * 增加如下配置可解决Spring Boot 6.x 与Swagger 3.0.0 不兼容问题
     **/
    @Bean
    public WebMvcEndpointHandlerMapping webEndpointServletHandlerMapping(WebEndpointsSupplier webEndpointsSupplier,
                                                                         ServletEndpointsSupplier servletEndpointsSupplier,
                                                                         ControllerEndpointsSupplier controllerEndpointsSupplier,
                                                                         EndpointMediaTypes endpointMediaTypes,
                                                                         CorsEndpointProperties corsProperties,
                                                                         WebEndpointProperties webEndpointProperties,
                                                                         Environment environment) {
        List> allEndpoints = new ArrayList();
        Collection webEndpoints = webEndpointsSupplier.getEndpoints();
        allEndpoints.addAll(webEndpoints);
        allEndpoints.addAll(servletEndpointsSupplier.getEndpoints());
        allEndpoints.addAll(controllerEndpointsSupplier.getEndpoints());
        String basePath = webEndpointProperties.getBasePath();
        EndpointMapping endpointMapping = new EndpointMapping(basePath);
        boolean shouldRegisterLinksMapping = this.shouldRegisterLinksMapping(webEndpointProperties, environment, basePath);
        return new WebMvcEndpointHandlerMapping(endpointMapping, webEndpoints, endpointMediaTypes, corsProperties.toCorsConfiguration(), new EndpointLinksResolver(allEndpoints, basePath), shouldRegisterLinksMapping, null);
    }


    private boolean shouldRegisterLinksMapping(WebEndpointProperties webEndpointProperties, Environment environment, String basePath) {
        return webEndpointProperties.getDiscovery().isEnabled() && (StringUtils.hasText(basePath) || ManagementPortType.get(environment).equals(ManagementPortType.DIFFERENT));
    }

}



3.编写代码Controller

@Api(tags = "测试接口")
@Controller
@RequestMapping("/test")
public class TestController {

    @Autowired
    private RedisTemplate redisTemplate;


    @ApiOperation("set value 操作")
    @ResponseBody
    @RequestMapping(value = "/set", method = RequestMethod.POST)
    public String setVal(String key, String value) {

        redisTemplate.opsForValue().set(key, value);

        return "success set val";
    }

    @ApiOperation("get 操作")
    @ResponseBody
    @RequestMapping(value = "/get", method = RequestMethod.GET)
    public String getValue(String key) {

        String result = (String) redisTemplate.opsForValue().get(key);

        System.err.println("======> 返回结果result：" + result);

        return result;
    }


}
