设置feign配置日志级别

设置feign配置日志级别

基于《<spring-cloud.version>Greenwich.RC2</spring-cloud.version>》

根据spring cloud文档: https://cloud.spring.io/spring-cloud-static/Greenwich.RC2/single/spring-cloud.html#_feign_logging

feign日志

在创建feign client的时候，就创建了logger, 默认logger的名称是创建feign client的服务接口类的全路径，通俗的来讲就是加了@FeignClient接口类的全路径

首先在application.yml文件中指定日志级别:

logging:
  level:
    com.**.api.service.IFeignService: DEBUG

设置日志记录的级别

logger有四种类型:NONE,BASIC,HEADERS, FULL,通过注册Bean来设置日志记录级别:

@Configuration
public class LogConfiguration {

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

}

在feign client加上：

@FeignClient(name = "IFeignService", configuration = LogConfiguration.class)
public interface IFeignService {

    @RequestMapping(value = "/index", method = RequestMethod.GET)
    public String invokeSayHi();

}

日志记录结果:
