java - spring boot 中使用 swagger2

• 1. 在 porm.xml 中添加依赖

    io.springfox
    springfox-swagger2
    2.2.2


    io.springfox
    springfox-swagger-ui
    2.2.2

• 2.在 Application 同级目录中添加 Swagger2 的配置类

@Configuration
@EnableSwagger2
public class Swagger2 {

    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(getApiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("org.xiaocai.web.controller"))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo getApiInfo() {
        return new ApiInfoBuilder()
                .title("小菜在使用swagger")
                .description("这是第一个尝试")
                .version("1.0")
                .build();
    }
}

注意需要配置扫描Controller路径 .apis(RequestHandlerSelectors.basePackage("org.xiaocai.web.controller"))

• 3. 在 Controller 中添加需要的文档说明

@RestController
public class CityRestController {

    @Autowired
    private CityService cityService;

    @ApiOperation(value="查找城市", notes="根据城市名查找城市")
    @RequestMapping(value = "/api/city", method = RequestMethod.GET)
    public City findOneCity(@ApiParam(name = "cityName", value = "城市名", required = true ) @RequestParam(value = "cityName", required = true) String cityName) {
        return cityService.findCityByName(cityName);
    }

}

• 4. 在浏览器中验证

  打开：
  http://localhost:8080/swagger-ui.html
