深入解析Spring Cloud Consul：让微服务间的通信和管理更简单

@Configuration
public class ConsulConfig {
 
    @Value("${spring.consul.host:localhost}")
    private String consulHost;
 
    @Value("${spring.consul.port:8500}")
    private int consulPort;
 
    @Bean
    public ConsulRegistration consulRegistration(ServiceInstanceLocalServiceInstance serviceInstance) {
        ConsulRegistration registration = new ConsulRegistration();
        registration.setServiceName("my-service");
        registration.setPort(serviceInstance.getPort());
        registration.setHealthCheckUrl("http://" + serviceInstance.getHost() + ":" + serviceInstance.getPort() + "/actuator/health");
        return registration;
    }
 
    @Bean
    public ConsulDiscoveryProperties consulDiscoveryProperties() {
        ConsulDiscoveryProperties properties = new ConsulDiscoveryProperties();
        properties.setHostname(consulHost);
        properties.setPort(consulPort);
        return properties;
    }
}

这段代码定义了一个配置类，它创建了两个Bean：ConsulRegistration和ConsulDiscoveryProperties。ConsulRegistration用于定义服务在Consul中的注册方式，包括服务名和健康检查URL；ConsulDiscoveryProperties用于配置Consul的主机和端口。这样，服务可以方便地注册到Consul并且其他服务可以发现和使用它。
