使用Feign logging 开启调用日志
作者:西蒙老爷
Feign logging开启调用日志
application.yml 配置
logging: level: yourproject.userClient: debug
FeignConfiguration
@Configuration public class FeignConfiguration { @Bean Logger.Level feignLoggerLevel() { return Logger.Level.FULL; } }
效果
参考官方:http://cloud.spring.io/spring-cloud-openfeign/single/spring-cloud-openfeign.html#_feign_logging
Feign启用日志
需求
想追踪Feign客户端发送的数据.
Feign在构建被@FeignClient注解修饰的服务客户端时,会为每一个客户端都创建一个feign.Logger实例,这样就可以利用该日志对象的DEBUG模式来帮助分析Feign的请求细节。
实现步骤
1. 在application.yml中使用 logging.level.<Feign客户端对应的接口的全限定名> 的参数配置格式来开启指定客户端日志.
logging: level: com: yc: springcloud2: service: IProductClientService: DEBUG #注意这里是Feign客户端接口的完整路径,这是我们要监控日志的接口
2. 但由于Feign客户端默认的Logger.Level对象定义为NONE级别,因此需要对它进行调整. Logger.Level的源码中规定了以下几个级别:
public enum Level { // 不记录日志 (默认)。 NONE, //只记录请求方法和URL以及响应状态代码和执行时间 BASIC, //记录请求和应答的头的基本信息 HEADERS, //记录请求和响应的头信息,正文和元数据 FULL }
那么如何将级别从NONE修改过来呢?这里有两种方式:
1. 全局配置: 在应用主配置类中加入 Logger.Level的Bean的创建和托管,这里这个应用中所有的Feign客户端都会按这个日志级别.
@SpringBootConfiguration public class FeignLogConfig { @Bean Logger.Level feignLoggerLevel(){ return Logger.Level.FULL; } }
运行 程序 [microservice-consumer-feign],查看输出结果。

2. 针对一个具体的Feign客户端单独配置. 比如这里对一个Feign客户端进行日志配置.
@Configuration public class FeignClientConfig { //加入安全配置 @Bean public BasicAuthRequestInterceptor getBasicAuthRequestInterceptor(){ return new BasicAuthRequestInterceptor("admin","a"); } @Bean Logger.Level feignLoggerLevel(){ return Logger.Level.FULL; } }
重启应用程序,查看输出:
