Eureka与Spring Cloud Bus的协同：打造智能服务发现新篇章

@Configuration
@ConditionalOnClass(EurekaDiscoveryClientConfiguration.class)
@ConditionalOnProperty(value = "spring.cloud.discovery.enabled", matchIfMissing = true)
@EnableConfigurationProperties(BusEurekaClientConfig.class)
public class EurekaBusConfiguration {
 
    @Autowired
    private BusEurekaClientConfig busEurekaClientConfig;
 
    @Autowired
    private ApplicationEventPublisher publisher;
 
    @Autowired(required = false)
    private List<SmartLifecycle> lifecycleList = new ArrayList<>();
 
    @Autowired
    private EurekaServiceRegistry registry;
 
    @Autowired
    private EurekaRegistryEndpoint registryEndpoint;
 
    @Bean
    public EurekaClientBootstrap eurekaClientBootstrap(ApplicationInfoManager manager) {
        return new EurekaClientBootstrap(manager, busEurekaClientConfig.getDeploymentUnitId(),
                busEurekaClientConfig.getNonSecurePort(), lifecycleList, publisher, registry, registryEndpoint);
    }
}

这个代码实例展示了如何在Spring Cloud应用中配置Eureka客户端以与Spring Cloud Bus协同工作。它定义了一个配置类，该类注册了EurekaClientBootstrap的Bean，这是一个负责在Eureka中注册服务以及监听消息总线事件的组件。这个例子简洁而完整，展示了如何将Eureka服务发现与消息总线整合在一起，为微服务架构提供了一个灵活的服务发现机制。
