Spring Cloud Zuul、Spectator和Atlas config

Question

现在我要介绍旁观者和图集。我似乎无法正确配置这个。如果我在Zuul服务上启用Atlas，则Atlas客户端的RestTemplate将失败，因为Ribbon试图包装它，而Ribbon不知道“Atlas”。如果我为Atlas添加功能区客户端配置，那么我的API网关将调用Break。有没有办法把地图集路线排除在彩带包裹之外？我错过了什么？见下文：

我定义了一个指向localhost主机名“atlas”。Atlas服务器正在运行。

Zuul/Api网关依赖项：

spring-boot-starter-parent: 1.3.2.RELEASE
spring-boot-starter-actuator
spring-cloud-starter-config
spring-cloud-starter-eureka
spring-cloud-starter-hystrix
spring-cloud-starter-zuul
spring-cloud-starter-stream-rabbit
spring-boot-starter-hateoas
spring-boot-starter-test
spring-cloud-starter-spectator
spring-cloud-starter-atlas

hystrix.command.default.execution.isolation.strategy: SEMAPHORE
netflix.atlas.uri=http://atlas:7101/api/v1/publish
server.port: ${PORT:8080}

spring.application.name=reservationClient
spring.cloud.config.uri=http://localhost:8888

Zuul/Eureka/Ribbon/Hystrix客户端均按预期工作，但Atlas客户端失败。

@SpringBootApplication
@EnableZuulProxy
@EnableHystrix
@EnableEurekaClient
@EnableAtlas
@EnableScheduling
public class APIGateway {

    @Autowired
    Registry registry;

    public static void main(String[] args) {
        SpringApplication.run(APIGateway.class, args);
    }
}

Atlas客户端被丝带缠绕，丝带不认识Atlas

好的，让我们为Atlas定义一个Ribbon客户端。

@SpringBootApplication
@EnableZuulProxy
@EnableHystrix
@EnableEurekaClient
@EnableAtlas
@EnableScheduling
public class APIGateway {

    @Autowired
    Registry registry;

    public static void main(String[] args) {
        SpringApplication.run(APIGateway.class, args);
    }
}

@Component
public class AtlasClientConfiguration {
    @Bean
    public StaticServerList ribbonServerList() {
        return new StaticServerList<Server>(new Server("atlas", 7101));
    }
}

我跌跌撞撞地找到了解决办法。

AtlasClientConfiguration不是一个组件，它只是一个提供StaticServerList的Bean。已删除@Component。

我需要显式命名我的RibbonClient配置。ie@RibbonClient（名称=“Atlas”，配置=AtlasClientConfiguration.class）

@SpringBootApplication
@EnableZuulProxy
@EnableHystrix
@EnableEurekaClient
@RibbonClient(name = "atlas", configuration = AtlasClientConfiguration.class)
@EnableAtlas
@EnableScheduling
public class APIGateway {

    @Autowired
    Registry registry;

    public static void main(String[] args) {
        SpringApplication.run(APIGateway.class, args);
    }
}


public class AtlasClientConfiguration {

    @Bean
    public StaticServerList<Server> ribbonServerList() {
        return new StaticServerList<Server>(new Server("atlas", 7101));
    }
}
