Fegin 请求日志查看配置

Fegin 请求日志查看配置

作者: 不想当码农的程序员 | 来源:发表于2017-10-09 19:53 被阅读157次

在spring cloud的项目中，使用Fegin做多个服务之间的调用，是很常见的事情，但是调用失败后虽然能进入熔断器中，但是具体的失败原因，或者日志，如果能看到，那么对开发调试，将会有很大的帮助。

步骤

1、配置FeignConfig

@Configuration
public class FeignConfig {


    /**
     * 配置请求重试
     * 
     */
    @Bean
    public Retryer feignRetryer() {
        return new Retryer.Default(200, SECONDS.toMillis(2), 10);
    }


    /**
     * 设置请求超时时间
     *默认
         * public Options() {
         * this(10 * 1000, 60 * 1000);
         * }
     *
     */
    @Bean
    Request.Options feignOptions() {
        return new Request.Options(60 * 1000, 60 * 1000);
    }



    /**
     * 打印请求日志
     * @return
     */
    @Bean
    public feign.Logger.Level multipartLoggerLevel() {
        return feign.Logger.Level.FULL;
    }

}

2、配置 FeignClient

@FeignClient(value = "test-service", fallback = TestServiceHystrix.class, configuration = FeignConfig.class)
public interface TestServiceClient {

    @PostMapping( value = "/upload",produces = {MediaType.APPLICATION_JSON_UTF8_VALUE},consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
     UpLoadResult upload(@RequestParam("upload") MultipartFile file);
}

3、请求接口，查看控制台日志

从我的日志中可以看到，这次请求失败了，并且能看到发出的请求url，方法类型，返回数据，负载均衡信息，请求的具体的集群ip等，这对我们调试有很大的帮助

关键设置

    @Bean
    public feign.Logger.Level multipartLoggerLevel() {
        return feign.Logger.Level.FULL;
    }
