1.在Apollo配置中心创建项目，并导入配置。

[
    {
        "name": "app-member",
        "location": "/app-mayikt-member/v2/api-docs",
        "version": "2.0"
    },
    {
        "name": "app-weixin",
        "location": "/app-mayikt-weixin/v2/api-docs",
        "version": "2.0"
    }
]

2.在Zuul网关中，导入依赖。

<!--阿波罗配置中心依赖-->
        <dependency>
            <groupId>com.ctrip.framework.apollo</groupId>
            <artifactId>apollo-client</artifactId>
            <version>1.0.0</version>
        </dependency>
        <dependency>
            <groupId>com.ctrip.framework.apollo</groupId>
            <artifactId>apollo-core</artifactId>
            <version>1.0.0</version>
        </dependency>

3.创建application.properties配置文件

app.id=app-mayikt-zuul #上图中的项目的appid
apollo.meta=http://172.20.10.3:8080  #阿波罗ip地址

4.在启动类上加上@EnableApolloConfig和@EnableSwagger2Doc

5.获取Swagger文档配置信息

   //获取ApolloConfig
   @ApolloConfig
   private Config config;
   
// 添加文档来源
   @Component
   @Primary
   class DocumentationConfig implements SwaggerResourcesProvider {
       @Override
       public List<SwaggerResource> get() {
           config.addChangeListener(new ConfigChangeListener() {
               // 开启监听，配置文件发生改变需要更改
               @Override
               public void onChange(ConfigChangeEvent configChangeEvent) {
                   get();
               }
           });
           return resources();
       }
       private List<SwaggerResource> resources(){
           List resources=new ArrayList();
           // 网关使用服务别名获取远程服务的SwaggerApi
           String swaggerDocJson=swaggerDocument();
           JSONArray jsonArray = JSONArray.parseArray(swaggerDocJson);
           for (Object object : jsonArray) {
               JSONObject jsonObject = (JSONObject) object;
               String name = jsonObject.getString("name");
               String location = jsonObject.getString("location");
               String version = jsonObject.getString("version");
               resources.add(swaggerResource(name, location, version));
           }
           return  resources;

       }

       /**
        * 获取swaggerDocument配置
        *
        * @return
        */
       private String swaggerDocument() {
           String property = config.getProperty("mayikt.zuul.swaggerDocument", "");
           return property;
       }

       private SwaggerResource swaggerResource(String name, String location, String version) {
           SwaggerResource swaggerResource = new SwaggerResource();
           swaggerResource.setName(name);
           swaggerResource.setLocation(location);
           swaggerResource.setSwaggerVersion(version);
           return swaggerResource;
       }

   }

6.阿波罗分布式配置中心监听

@Component
@Slf4j
public class MyCommandLineRunner implements CommandLineRunner {
	@ApolloConfig
	private Config config;

	@Override
	public void run(String... args) throws Exception {
		config.addChangeListener(new ConfigChangeListener() {

			@Override
			public void onChange(ConfigChangeEvent changeEvent) {
				log.debug("####分布式配置中心监听#####" + changeEvent.changedKeys().toString());
			}
		});
	}

}
