3.2.2 支付微服务提供者Controller修改

    @GetMapping("/payment/getInfo")
    public ResponseResult getInfo() {
        try {
            Thread.sleep(3000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        String value = UUID.randomUUID().toString() + ":" + serverPort;
        return new ResponseResult(200, "成功", value);
    }

3.2.3.订单微服务消费者server

package cn.bdqn.service;
 
import cn.bdqn.bean.ResponseResult;
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(name="springcloud-payment-provider-service")
public interface PaymentFeignServer {
 
    @GetMapping("/payment/get/{id}")
    public ResponseResult queryId(@PathVariable(name = "id") Integer id);
 
    @GetMapping("/payment/getInfo")
    public ResponseResult getInfo();
}

3.2.4.订单微服务消费者controller

package cn.bdqn.controller;
 
import cn.bdqn.bean.ResponseResult;
import cn.bdqn.service.PaymentFeignServer;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;
 
@RestController
public class OrderController {
 
    @Autowired
    private PaymentFeignServer  paymentFeiginService;
 
    @GetMapping(value = "/consumer/payment/get/{id}")
    public ResponseResult getPaymentByID(@PathVariable("id") Integer id) {
        return paymentFeiginService.queryId(id);
    }
 
    @GetMapping(value = "/consumer/payment/getInfo")
    public ResponseResult getInfo() {
        return paymentFeiginService.getInfo();
    }
}

3.2.6解决方案

server:
  port: 80
eureka:
  client:
    register-width-eureka: false
    service-url: # 配置服务中心，openFeign去里面找服务
        defaultZone: http://eureka7001.com:7001/eureka/,
                     http://eureka7002.com:7002/eureka/,
                     http://eureka7003.com:7003/eureka/,
    instance:
      prefer-ip-address: true,
ribbon:
  #指的是建立连接后从服务器读取到可用资源所用的时间 
  ReadTimeout: 5000
  #指的是建立连接所用的时间  适用于网络状态正常的情况下，两端连接所用的时间
  ConnectTimeout: 5000

4.3配置日志Bean

package cn.bdqn.config;
 
import feign.Logger;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
 
 
@Configuration
public class FeignLogConfig {
    @Bean
   public Logger.Level feignLoggerLever(){
       return Logger.Level.FULL;
   }
 
}

 4.4YML 文件里需要开启日志的Feign客户端

server:
  port: 80
eureka:
  client:
    register-width-eureka: false
    service-url: # 配置服务中心，openFeign去里面找服务
        defaultZone: http://eureka7001.com:7001/eureka/,
                     http://eureka7002.com:7002/eureka/,
                     http://eureka7003.com:7003/eureka/,
    instance:
      prefer-ip-address: true,
ribbon:
  #指的是建立连接后从服务器读取到可用资源所用的时间
  ReadTimeout: 5000
  #指的是建立连接所用的时间  适用于网络状态正常的情况下，两端连接所用的时间
  ConnectTimeout: 5000
logging:
  level:
    cn.bdqn.service.PaymentFeignService: debug
