feign开启日志Logger.Level feignLoggerLevel()中Level爆红的解决
开启日志Logger.Level feignLoggerLevel()中Level爆红
feign开启日志
配置和说明
如果只想让某一个feign调用的时候有日志怎么办
开启日志Logger.Level feignLoggerLevel()中Level爆红今天在学习feign时测试其配置日志的功能，发现Logger不存在Level方法，百度了一圈没有找到方法
结果自己摸索发现是导错了包，如下是错误的包
应该导入feign中的Logger包，如下
配置
feign出于性能考虑,默认是没有日志的,需要手动开启.

@Bean
public Logger.Level feignLoggerLevel() {
return Logger.Level.FULL;
}
}
BASIC级别
只输出请求方法的 URL 和响应的状态码以及接口执行的时间。
@Bean
public Logger.Level feignLoggerLevel() {
return Logger.Level.BASIC;
}
当feign进行远程调用的时候控制台输出:

在Java代码里面配置
可以用configuration = Feign2Config.class 来指定你的feign配置文件,然后在这个FeignConfig.class 配置文件里面配置日志,这样的话,只有这一个feign接口类打印日志了
需要注意的是Feign2Config不要加@Configuration注解,因为如果加了的话,就成了全局配置类了,那么所有的feign接口都会使用这个配置文件了.
@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);

/**

*/
@Bean
public Logger.Level feignLoggerLevel() {
return Logger.Level.FULL;
}
}
在yaml里面配置
这样 mall-order微服务的feign日志级别就是FULL了.
feign:
client:
config:
mall-order: #对应微服务
loggerLevel: FULL
以上为个人经验，希望能给大家一个参考，也希望大家多多支持软件开发网。
