[Spring cloud 一步步实现广告系统] 5. 投放系统配置+启动+实体类

/**
 * SponsorApplication for 广告赞助商/投递服务启动类
 * 添加注解{@link EnableFeignClients}之后，当前微服务就可以调用别的微服务，
 * 但是当前服务是广告提供，不需要调用别的微服务，在此只是为了在dashboard中监控
 * {@link EnableCircuitBreaker} 也是为了dashboard监控

@EnableDiscoveryClient //开启服务发现Eureka Client
@EnableCircuitBreaker //开启断路器
@EnableFeignClients //开启feign client，使其可以通过HTTP调用其他微服务

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