您的源代碼在哪裏？我懷疑任何人都可以用你提供的信息來幫助你。 –

這看起來好像很久以前就放棄了，沒有任何要求澄清的行動。現在投票結束。 – halfer

我認爲您的假裝客戶端的方法簽名的@RequestMapping註釋缺少一個方法參數，例如GET或POST - 請參閱下面的代碼示例：

@FeignClient("client") 
public interface MyClient { 
    @RequestMapping(method = RequestMethod.GET, value = "/path-to-endpoint") 
    MyResponse getMyResponse(); 
}
