Zuul中整合Swagger2,实现对源服务API测试

我们知道,Swagger2整合到项目中,可以非常方便地进行接口测试,是前后端对接效率提高。现在,我们可以在Zuul中整合Swagger2,通过Zuul配置文件配置的映射路径,来生成源服务接口的测试Dashboard。
1、zuul-service中配置
1、1 pom.xml中引入swagger2相关jar包

... io.springfox springfox-swagger2 2.7.0 io.springfox springfox-swagger-ui 2.7.0 ...

1、2 配置swagger2
import org.springframework.beans.factory.annotation.Autowired; import org.springframework.cloud.netflix.zuul.filters.Route; import org.springframework.cloud.netflix.zuul.filters.discovery.DiscoveryClientRouteLocator; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.Primary; import springfox.documentation.swagger.web.SwaggerResource; import springfox.documentation.swagger.web.SwaggerResourcesProvider; import springfox.documentation.swagger2.annotations.EnableSwagger2; import java.util.ArrayList; import java.util.List; /** * 请求地址:http://localhost:18600/swagger-ui.html * @author jackcooper * @create 2018-06-25 17:55 */ @Configuration @EnableSwagger2 public class SwaggerConfig {@Autowired private DiscoveryClientRouteLocator discoveryClientRouteLocator; @Primary @Bean public SwaggerResourcesProvider swaggerResourcesProvider() { return new SwaggerResourcesProvider() { @Override public List get() { List resources = new ArrayList<>(); for (Route route : discoveryClientRouteLocator.getRoutes()) { resources.add(createResource(route.getLocation(),route.getId(), "2.0")); } return resources; } }; }private SwaggerResource createResource(String name, String location, String version) { SwaggerResource swaggerResource = new SwaggerResource(); swaggerResource.setName(name); swaggerResource.setLocation("/" + location + "/v2/api-docs"); swaggerResource.setSwaggerVersion(version); return swaggerResource; } }

2、源服务中配置
2.1 pom.xml中引入依赖
... io.springfox springfox-swagger2 2.7.0 ...

2.2 Swagger2配置类
import org.springframework.boot.autoconfigure.condition.ConditionalOnExpression; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import springfox.documentation.builders.ApiInfoBuilder; import springfox.documentation.builders.PathSelectors; import springfox.documentation.builders.RequestHandlerSelectors; import springfox.documentation.service.ApiInfo; import springfox.documentation.spi.DocumentationType; import springfox.documentation.spring.web.plugins.Docket; import springfox.documentation.swagger2.annotations.EnableSwagger2; /** * @author jackcooper * @create 2017-07-03 12:34 */ @Configuration @EnableSwagger2 public class Swagger2 {private ApiInfo apiInfo() { return new ApiInfoBuilder() .title(swaggerTitle) .description(swaggerDescription) .termsOfServiceUrl(termsOfServiceUrl) .contact(new Contact(swaggerContactName, swaggerContactUrl, swaggerContactEmail)) .license(swaggerLicense) .licenseUrl(swaggerLicenseUrl) .version(swaggerVersion) .build(); }@Bean public Docket init() { return new Docket(DocumentationType.SWAGGER_2) //*** 注意:此处groupName不能配置,否则举合失败 //.groupName("api首页") .apiInfo(apiInfo()) .select() .apis(RequestHandlerSelectors.basePackage("com.saos.bd.api")) .paths(PathSelectors.any()) .build() .pathMapping("/") .useDefaultResponseMessages(false) .globalResponseMessage(RequestMethod.GET, this.extractStatusCodes()) .globalResponseMessage(RequestMethod.POST, this.extractStatusCodes()) .globalResponseMessage(RequestMethod.PUT, this.extractStatusCodes()) .globalResponseMessage(RequestMethod.DELETE, this.extractStatusCodes()) .alternateTypeRules(new AlternateTypeRule[0]) .forCodeGeneration(false); }private List extractStatusCodes() { final LinkedList list = new LinkedList<>(); for (StatusCode sc : StatusCode.values()) { ResponseMessage message = new ResponseMessageBuilder() .code(sc.getCode()) .message(sc.getMessage()) .build(); list.add(message); } return list; }

2.3 Controller添加Swagger2的注解
import io.swagger.annotations.Api; import io.swagger.annotations.ApiOperation; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RestController; @Api(description = "测试源服务API接口") @RestController public class TestController {@ApiOperation(value = "https://www.it610.com/article/加法", notes = "加法") @GetMapping("/add") public Integer add(Integer a, Integer b){ return a + b; } @ApiOperation(value = "https://www.it610.com/article/减法", notes = "减法") @GetMapping("/sub") public Integer sub(Integer a, Integer b){ return a - b; } @ApiOperation(value = "https://www.it610.com/article/乘法", notes = "乘法") @GetMapping("/mul") public Integer mul(Integer a, Integer b){ return a * b; } @ApiOperation(value = "https://www.it610.com/article/除法", notes = "除法") @GetMapping("/div") public Integer div(Integer a, Integer b){ return a / b; } }

swagger2注解说明:
详解:https://my.oschina.net/zzuqiang/blog/793606
@Api:用在请求的类上,表示对类的说明 tags="说明该类的作用,可以在UI界面上看到的注解" value="https://www.it610.com/article/该参数没什么意义,在UI界面上也看到,所以不需要配置"@ApiOperation:用在请求的方法上,说明方法的用途、作用 value="https://www.it610.com/article/说明方法的用途、作用" notes="方法的备注说明"@ApiImplicitParams:用在请求的方法上,表示一组参数说明 @ApiImplicitParam:用在@ApiImplicitParams注解中,指定一个请求参数的各个方面 name:参数名 value:参数的汉字说明、解释 required:参数是否必须传 paramType:参数放在哪个地方 · header --> 请求参数的获取:@RequestHeader · query --> 请求参数的获取:@RequestParam · path(用于restful接口)--> 请求参数的获取:@PathVariable · body(不常用) · form(不常用) dataType:参数类型,默认String,其它值dataType="Integer" defaultValue:参数的默认值@ApiResponses:用在请求的方法上,表示一组响应 @ApiResponse:用在@ApiResponses中,一般用于表达一个错误的响应信息 code:数字,例如400 message:信息,例如"请求参数没填好" response:抛出异常的类@ApiModel:用于响应类上,表示一个返回响应数据的信息 (这种一般用在post创建的时候,使用@RequestBody这样的场景, 请求参数无法使用@ApiImplicitParam注解进行描述的时候) @ApiModelProperty:用在属性上,描述响应类的属性

3、 最终效果图
运行所有微服务,请求网关地址(zuul-server)http://ip:18600/swagger-ui.html地址。
