对绝大多数程序员而言,写接口文档是一件痛苦的事情,相对文档,他们更愿意写代码。最理想的情况就是:代码即文档!服务开发完成后,部署上去文档就自动生成,没错,这就是springfox + swagger要解决的问题!
号称 THE WORLD'S MOST POPULAR API TOOLING。但swagger默认情况下,仍要单独部署,程序员还是要跑到一个单独的web页面上编辑,写一堆yaml文档,依然不爽。
github上有一个项目,可以在开发rest服务时,只要加一些注解,就自动生成swagger-ui界面,以及相关的文档,而且可以跟spring-boot/spring-cloud无缝集成。
步骤:
一、添加依赖项
dependencies { ... compile "io.springfox:springfox-swagger2:2.7.0" compile "io.springfox:springfox-swagger-ui:2.7.0" ... }
二、添加swagger配置类
1 package cn.mwee.order.cloud.service.express.config; 2 3 import org.springframework.context.annotation.Bean; 4 import org.springframework.context.annotation.Configuration; 5 import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry; 6 import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter; 7 import springfox.documentation.builders.ApiInfoBuilder; 8 import springfox.documentation.builders.PathSelectors; 9 import springfox.documentation.builders.RequestHandlerSelectors;10 import springfox.documentation.service.ApiInfo;11 import springfox.documentation.service.Contact;12 import springfox.documentation.spi.DocumentationType;13 import springfox.documentation.spring.web.plugins.Docket;14 import springfox.documentation.swagger2.annotations.EnableSwagger2;15 16 /**17 * Created by yangjunming on 13/10/2017.18 */19 @Configuration20 @EnableSwagger221 public class SwaggerConfig {22 23 @Bean24 public Docket createRestApi() {25 return new Docket(DocumentationType.SWAGGER_2)26 .apiInfo(apiInfo())27 .select()28 .apis(RequestHandlerSelectors.basePackage("xxx.controller")) //Controller所在的package29 .paths(PathSelectors.any())30 .build();31 }32 33 @Bean34 public WebMvcConfigurerAdapter addResourceHandlers() {35 return new WebMvcConfigurerAdapter() {36 @Override37 public void addResourceHandlers(ResourceHandlerRegistry registry) {38 registry.addResourceHandler("swagger-ui.html")39 .addResourceLocations("classpath:/META-INF/resources/");40 registry.addResourceHandler("/webjars/**")41 .addResourceLocations("classpath:/META-INF/resources/webjars/");42 }43 };44 }45 46 private ApiInfo apiInfo() {47 return new ApiInfoBuilder()48 .title("express-service online api document")49 .description("某某服务") 50 .contact(new Contact("作者名字", "http://作者介绍网址", "作者@邮箱.com"))51 .version("1.0.0") //显示版本号52 .build();53 }54 }
三、在Controller上添加注解
1 package cn.mwee.order.cloud.service.express.controller; 2 3 import cn.mwee.order.cloud.admin.common.controller.AbstractController; 4 import cn.mwee.order.cloud.admin.service.dto.common.DataResult; 5 import cn.mwee.order.cloud.admin.service.dto.express.sf.*; 6 import cn.mwee.order.cloud.admin.service.express.SFExpressService; 7 import io.swagger.annotations.Api; 8 import io.swagger.annotations.ApiOperation; 9 import org.springframework.beans.factory.annotation.Autowired;10 import org.springframework.cloud.context.config.annotation.RefreshScope;11 import org.springframework.web.bind.annotation.PostMapping;12 import org.springframework.web.bind.annotation.RequestBody;13 import org.springframework.web.bind.annotation.RequestMapping;14 import org.springframework.web.bind.annotation.RestController;15 16 import javax.servlet.http.HttpServletRequest;17 18 /**19 * Created by 菩提树下的杨过(http://yjmyzz.cnblogs.com/) on 2017/7/18.20 */21 @RestController22 @RefreshScope23 @RequestMapping("/sf")24 @Api(consumes = "application/json",25 produces = "application/json",26 protocols = "http",27 basePath = "/sf", value = "顺丰对接服务")28 public class SFController extends AbstractController {29 30 ...31 32 @ApiOperation(value = "下单", tags = "顺丰速运")33 @PostMapping(value = "submitOrder")34 public DataResultsubmitOrder(@RequestBody SFSubmitOrderRequest request) throws Exception {35 return ...;36 }37 38 ...39 40 }
注意上面几处带@Api开头的注解
四、参数实体上添加注解
1 package cn.mwee.order.cloud.admin.service.dto.express.sf; 2 3 import cn.mwee.order.cloud.admin.service.dto.express.ExpressBaseOrder; 4 import cn.mwee.order.common.utils.date.DateUtil; 5 import com.alibaba.fastjson.annotation.JSONField; 6 import io.swagger.annotations.ApiModel; 7 import io.swagger.annotations.ApiModelProperty; 8 import lombok.Data; 9 import lombok.EqualsAndHashCode;10 11 import java.util.ArrayList;12 import java.util.Date;13 import java.util.List;14 15 /**16 * 顺丰的物流订单17 * Created by 菩提树下的杨过(http://yjmyzz.cnblogs.com/) on 26/09/2017.18 */19 @Data20 @EqualsAndHashCode(callSuper = false)21 @ApiModel(description = "顺丰-提交订单参数")22 public class SFSubmitOrderRequest extends ExpressBaseOrder {23 24 @ApiModelProperty(value = "商家编码(顺丰分配提供)", required = true, dataType = "String", example = "A001")25 private String clientCode; //商家编码,为顺丰分配提供26 27 ...28 }
还是注意上面几处带@Api开头的注解,一看就懂。
启动后,就可以用 http://xxxx.xxxx:port/swagger-ui.html访问了
随便点开一个方法,比如cancelOrder
还可以直接调用REST(相当于postman之类的rest服务测试工具了)
