SpringCloud 实战十三：Feign的日志增强

1、feign客户端添加配置

feign日志级别

package com.laoxu.springcloud.config;

import feign.Logger;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class FeignConfig {

    @Bean
    Logger.Level feignLoggerLevel(){
        return Logger.Level.FULL;
    }
}

2、配置feign日志

logging:
  level:
    # feign日志以什么级别监控哪个接口
    com.laoxu.springcloud.service.PaymentService: debug

3、访问：http://localhost/consumer/payment/get/31

可以看到Debug详细日志：
