springboot启动报错: Consider defining a bean of type ‘XXX‘ in your configuration

Consider defining a bean of type ‘XXX’ in your configuration

出现这个错误，要看看你是否用到了某些组件，但是启动类上没加相应的注解。比如说我就是因为在service层用到了@FeignClient注解，但是在启动类上忘了加上@EnableFeignClients注解，才导致的报错，写代码一定要细心啊。

异常信息如下：

Description:

A component required a bean of type 'com.atgugu.springcloud.service.PaymentHystrixService' that could not be found.


Action:

Consider defining a bean of type 'com.atgugu.springcloud.service.PaymentHystrixService' in your configuration.

service层代码如下：

package com.atgugu.springcloud.service;

import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.stereotype.Component;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;

@Component
@FeignClient(value = "CLOUD-PROVIDER-HYSTRIX-PAYMENT")//使用FeignClient作服务调用
public interface PaymentHystrixService {

    @GetMapping(value = "/payment/hystrix/ok/{id}")
    public String paymentInfo_OK(@PathVariable("id") Integer id);

    @GetMapping(value = "/payment/hystrix/timeout/{id}")
    public String paymentInfo_TimeOut(@PathVariable("id") Integer id);
}

启动类代码如下：

package com.atgugu.springcloud;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloudflix.hystrix.EnableHystrix;
import org.springframework.cloud.openfeign.EnableFeignClients;

@SpringBootApplication
@EnableFeignClients//使用FeignClient记得添加@EnableFeignClients注解
@EnableHystrix
public class OrderHystrixMain80 {
    public static void main(String[] args) {
        SpringApplication.run(OrderHystrixMain80.class, args);
    }
}

谢谢观看，我爱这魔幻的代码！
