開啟日志Logger.Level feignLoggerLevel()中Level爆紅

今天在學(xué)習(xí)feign時(shí)測試其配置日志的功能，發(fā)現(xiàn)Logger不存在Level方法，百度了一圈沒有找到方法

結(jié)果自己摸索發(fā)現(xiàn)是導(dǎo)錯(cuò)了包，如下是錯(cuò)誤的包

應(yīng)該導(dǎo)入feign中的Logger包，如下

feign開啟日志

feign出于性能考慮,默認(rèn)是沒有日志的,需要手動(dòng)開啟.

如果只想讓某一個(gè)feign調(diào)用的時(shí)候有日志怎么辦

在Java代碼里面配置

可以用configuration = Feign2Config.class 來指定你的feign配置文件,然后在這個(gè)FeignConfig.class 配置文件里面配置日志,這樣的話,只有這一個(gè)feign接口類打印日志了

需要注意的是Feign2Config不要加@Configuration注解,因?yàn)槿绻恿说脑?就成了全局配置類了,那么所有的feign接口都會(huì)使用這個(gè)配置文件了.

@FeignClient(value = "mall-order",path = "/order",configuration = Feign2Config.class)
public interface OrderFeignService {
? ? @RequestMapping("/findOrderByUserId/{userId}")
? ? R findOrderByUserId(@PathVariable("userId") Integer userId);
? ? @RequestMapping(value = "/save",consumes = MediaType.APPLICATION_JSON_VALUE)
? ? R save(@RequestBody OrderVo order);

package com.tuling.mall.feigndemo.config;
import com.tuling.mall.feigndemo.interceptor.FeignAuthRequestInterceptor;
import feign.Contract;
import feign.Logger;
import feign.Request;
import feign.auth.BasicAuthRequestInterceptor;
import feign.codec.Decoder;
import feign.codec.Encoder;
import feign.jackson.JacksonDecoder;
import feign.jackson.JacksonEncoder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
//@Configuration // 注意,這個(gè)配置了@Configuration之后就是全局的bean了,就需要成了全局配置了
public class Feign2Config {
? ? /**
? ? ?* 日志級別
? ? ?* 通過源碼可以看到日志等級有 4 種，分別是：
? ? ?* NONE：不輸出日志。
? ? ?* BASIC：只輸出請求方法的 URL 和響應(yīng)的狀態(tài)碼以及接口執(zhí)行的時(shí)間。
? ? ?* HEADERS：將 BASIC 信息和請求頭信息輸出。
? ? ?* FULL：輸出完整的請求信息。
? ? ?*/
? ? @Bean
? ? public Logger.Level feignLoggerLevel() {
? ? ? ? return Logger.Level.FULL;
? ? }
}

在yaml里面配置

這樣 mall-order微服務(wù)的feign日志級別就是FULL了.

feign:
? client:
? ? config:
? ? ? mall-order: ?#對應(yīng)微服務(wù)
? ? ? ? loggerLevel: FULL

以上為個(gè)人經(jīng)驗(yàn)，希望能給大家一個(gè)參考，也希望大家多多支持腳本之家。
