问题出现：springcloud架构中配置消费者服务后启动时报错
问题描述：
A component required a bean of type ‘org.springframework.web.client.RestTemplate’ that could not be found.
问题截图：

出现原因：
在 Spring Boot 1.3版本中，会默认提供一个RestTemplate的实例Bean，而在 Spring Boot 1.4以及以后的版本中，这个默认的bean不再提供了，我们需要在Application启动时，手动创建一个RestTemplate的配置。
解决方法：
在启动类中添加该实例：

 @BeanRestTemplate restTemplate(){return new RestTemplate();}
