Feign配置日志的打印級別

一、細粒度的配置Feign的日志級別（針對每個微服務配置）

　1、java代碼方式

       （1）在Feign接口注解上面配置configuration 

/**
 * @author : maybesuch
 * @version : 1.0
 * @Description : 用戶中心Feign接口
 * @Date : 2020/1/9 11:43
 * @Copyright : Copyright (c) 2020 All Rights Reserved
 **/
@FeignClient(value = "user-center", configuration = UserCenterFeignConfiguration.class)
public interface UserCenterFeignClient {

    @GetMapping("/users/{id}")
    UserDTO findById(@PathVariable("id") Integer id);

}

    （2）定義configuration內容，也就是feign的日志級別

            Logger有四種類型：NONE(默認)、BASIC、HEADERS、FULL，通過注冊Bean來設置日志記錄級別

            注意：在此方法上不需要@Configuration注解，否則會被所有的FeignClient共享，如果添加了注解，則需要將此類放到啟動時掃描不到的包

/**
 * @author : maybesuch
 * @version : 1.0
 * @Description : 定義請求用戶中心Feign的日志級別
 * @Date : 2020/1/9 17:24
 * @Copyright : Copyright (c) 2020 All Rights Reserved
 **/
public class UserCenterFeignConfiguration {

    @Bean
    Logger.Level feignLoggerLevel(){
        // 設置日志
        return Logger.Level.FULL;
    }
}

     （3）將Feign的全路徑在application.yml中配置 

logging:
  level:
#    com.maybesuch.contentcenter.feignclient.UserCenterFeignClient: debug
    com.maybesuch: debug

 

    2、配置文件的方式

        只需在application.yml中添加配置：   

logging:
  level:
#    com.maybesuch.contentcenter.feignclient.UserCenterFeignClient: debug
    com.maybesuch: debug

feign:
  client:
    config:
      # 要調用服務的名稱
      user-center:
        loggerLevel: full

 

二、全局日志級別的配置

    1、java代碼的方式

     （1）在啟動類@EnableFeignClients注解上配置defaultConfiguration 

@SpringBootApplication
@EnableFeignClients(defaultConfiguration = GlobalFeignConfiguration.class)
public class ContentCenterApplication {

    public static void main(String[] args) {
        SpringApplication.run(ContentCenterApplication.class, args);
    }
}

    （2）定義GlobalFeignConfiguration類，此類也不需要@Configuration注解

/**
 * @author : maybesuch
 * @version : 1.0
 * @Description : 定義全局Feign的日志級別
 * @Date : 2020/1/9 17:24
 * @Copyright : Copyright (c) 2020 All Rights Reserved
 **/
public class GlobalFeignConfiguration {

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

    （3）配置文件application.yml中需配置日志級別方能打印出Feign調用的日志信息

logging:
  level:
    com.maybesuch: debug

 

2、配置文件方式

 　　只需在application.yml中添加配置：

logging:
  level:
    com.maybecare: debug

feign:
  client:
    config:
      # feign全局日志級別
      default:
        loggerLevel: full

 

日志打印結果：
