SpringCloud（十三）：Feign的demo之日志

日志输出的配置很简单。

在原先的基础上更改两处，一是application.yml中添加：

logging:
  level:
    com.itmuch.cloud.feign.UserFeignClient: DEBUG

二是在Configuration1.java中添加：

@Bean
Logger.Level feignLoggerLevel()
{
	return Logger.Level.FULL;
}

启动测试，访问：http://192.168.80.1:7901/movie/1

可以看到控制台打出debug日志：

注意在你第一次做请求的时候和上篇同样都会有一个问题，控制台报timeout超时的问题。下篇将为您解答，敬请期待。。。
