如何将微服务swaggers聚合成一个招摇

Question

我试图在我的微服务项目中产生一个招摇，在Api网关中将所有服务swaggers聚合成一个。为了实现这一点，我正在关注下一个教程https://objectpartners.com/2017/09/28/aggregate-services-into-a-single-swagger

这里的问题是，当我尝试设置绝对URL时，我收到的输出是无法加载API定义。 undefined http://localhost:8070/apihttp://localhost:8081/api/v2/api-docs其中localhost：8070 / api是api网关的基本URL，localhost：8081 / api / v2 / api-docs是微服务swagger的docs URL。

这是我的代码：

SwaggerConfiguration

package com.rfd.apigateway.swagger;

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;

import java.util.List;

@Configuration
@ConfigurationProperties(prefix = "swagger")
public class SwaggerConfiguration {

    private List<Resource> resources;

    public List<Resource> getResources() {
        return resources;
    }

    public void setResources(List<Resource> resources) {
        this.resources = resources;
    }
}

资源

package com.rfd.apigateway.swagger;

public class Resource {
    private String name;
    private String url;
    private String version;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getUrl() {
        return url;
    }

    public void setUrl(String url) {
        this.url = url;
    }

    public String getVersion() {
        return version;
    }

    public void setVersion(String version) {
        this.version = version;
    }
}

DocumentationController

package com.rfd.apigateway.swagger;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.Primary;
import org.springframework.stereotype.Component;
import springfox.documentation.swagger.web.SwaggerResource;
import springfox.documentation.swagger.web.SwaggerResourcesProvider;

import java.util.ArrayList;
import java.util.List;

@Component
@Primary
@EnableAutoConfiguration
public class DocumentationController implements SwaggerResourcesProvider {

    private SwaggerConfiguration swaggerConfiguration;

    @Autowired
    public DocumentationController(SwaggerConfiguration swaggerConfiguration){
        this.swaggerConfiguration = swaggerConfiguration;
    }

    @Override
    public List get() {
        List resources = new ArrayList<>();
        for(Resource resource : this.swaggerConfiguration.getResources()){
            resources.add(createSwaggerResource(resource));
        }

        return resources;
    }

    private SwaggerResource createSwaggerResource(Resource resource) {
        SwaggerResource swaggerResource = new SwaggerResource();
        swaggerResource.setName(resource.getName());
        swaggerResource.setUrl(resource.getUrl());
        swaggerResource.setSwaggerVersion(resource.getVersion());
        return swaggerResource;
    }
}

最后，application.yml

swagger:
  resources:
    - name: transactions
      url: http://localhost:8081/api/v2/api-docs
      version: 1.0
    - name: payments
      url: http://localhost:8083/api/v2/api-docs
      version: 1.0
