Springboot 整合 Swagger 3

1：引入依赖

       <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-boot-starter</artifactId>
            <version>3.0.0</version>
        </dependency>

2：编写一个swagger 配置类

@Configuration
@EnableWebMvc
@EnableOpenApi
public class SwaggerConfig {
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.example.demotest.controller"))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("程序猿xiaoxia API")
                .description("xiaoxia springboot-swagger2 在线借口文档")
                .termsOfServiceUrl("https://blog.csdn.net/XikYu")
                .version("1.0")
                .build();
    }

}

3：在controller层中填写一些注解

@RestController
@RequestMapping("/department")
@SuppressWarnings("all")
//@RequiredArgsConstructor(onConstructor = @__(@Autowired))
public class DepartmentController {

    @Resource
    private  DepartmentService departmentService;

    @PostMapping("treeDepartment")
    @ApiOperation(value = "树形化结构数据")
    public Result treeDepartment(){
        List<Department> departmentAll = departmentService.findDepartmentAll();
        return new Result(ResultCode.SUCCESS,departmentAll);
    }
}
