Feign 报错：Request method 'POST' not supported

如果Fegin代理的是get请求，那么请求参数必须带上@RequestParam 或@RequestBody

错误：

@FeignClient("dashboard")
public interface DashboardClient {

  @GetMapping("projects/getApiKeyByProjectId")
  String getApiKeyByProjectId(Integer projectId);
}

正确：

@FeignClient("dashboard")
public interface DashboardClient {

  @GetMapping("projects/getApiKeyByProjectId")
  String getApiKeyByProjectId(@RequestParam Integer projectId);
}
