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 = "加法", notes = "加法")
    @GetMapping("/add")
    public Integer add(Integer a, Integer b){
        return a + b;
    }
    @ApiOperation(value = "减法", notes = "减法")
    @GetMapping("/sub")
    public Integer sub(Integer a, Integer b){
        return a - b;
    }
    @ApiOperation(value = "乘法", notes = "乘法")
    @GetMapping("/mul")
    public Integer mul(Integer a, Integer b){
        return a * b;
    }
    @ApiOperation(value = "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="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="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
