超详细讲解SpringCloud Commons公共抽象的用法

@Configuration

public class MyConfiguration {
    private ServiceRegistry registry;

    public MyConfiguration(ServiceRegistry registry) {
        this.registry = registry;
    }
    // called via some external process, such as an event or a custom actuator endpoint
    public void register() {
        Registration registration = constructRegistration();
        this.registry.register(registration);
    }
}

@Configuration
public class MyConfiguration {

//使用restTemplate访问my-application微服务的/name接口

return name;
}
}
