Spring cloud 两种服务调用方式(Rest + Ribbon) 和 Fegin方式

1:Rest + Ribbon 

    @Bean
    @LoadBalanced
    RestTemplate restTemplate() {
        return new RestTemplate();
    }

　　@Autowired
    RestTemplate restTemplate;

    public String hiService(String name) {
        return restTemplate.getForObject("http://hi-service/hi?name="+name,String.class);
    }

 

2:Fegin默认 集成Ribbon

//控制器    
 　　@Autowired
    SchedualServiceHi schedualServiceHi;

    @RequestMapping(value = "/hi",method = RequestMethod.GET)
    public String sayHi(@RequestParam String name){
        return schedualServiceHi.sayHiFromClientOne(name);
    }

// 添加一个接口方法
@FeignClient(value = "hi-service")
public interface SchedualServiceHi {
    @RequestMapping(value = "/hi",method = RequestMethod.GET)
    String sayHiFromClientOne(@RequestParam(value = "name") String name);
}
