写了一个天气功能的demo：

别的就不秀了，直接上核心

1. package com.example.weather;
   
2. 
   
3. import org.springframework.cloud.openfeign.FeignClient;
   
4. import org.springframework.web.bind.annotation.GetMapping;
   
5. import org.springframework.web.bind.annotation.RequestParam;
   
6. 
   
7. @FeignClient(name = "weatherClient", url = "https://api.openweathermap.org/data/2.5")
   
8. public interface WeatherClient {
   
9. 
   
10.     @GetMapping("/weather")
    
11.     WeatherResponse getWeather(@RequestParam("q") String city,
    
12.                                 @RequestParam("appid") String apiKey);
    
13. }
