跟踪 ID 未显示在控制器级别日志中(Spring 启动、Jaeger 配置) [英] Trace id is not shown on controller level log (Spring boot, Jaeger configuration)

问题描述

语言:Java

框架:Spring Boot

工具:Jaeger

我已经完成了以下配置以将整个跟踪记录在日志上.但在控制器级别日志没有显示跟踪.当执行休眠查询时比跟踪放在日志上(在服务和存储库级别日志上)

I have done the following configuration for put whole trace on logs. But at controller level log not shown a trace. when hibernate query executed than after trace is put on logs(on service and repository level logs)

public class MDCReporter implements Reporter {

    public MDCReporter() {
        // default constructor
    }

    @Override
    public void report(JaegerSpan span) {
        MDC.put("traceinfo", span);
    }

Appender 类

public class JaegerReportAppender implements ReporterAppender {

    public JaegerReportAppender() {
        // default constructor
    }

    @Override
    public void append(Collection<Reporter> reporters) {
        reporters.add(new MDCReporter());

    }
}

主要的spring boot类

Main spring boot class

@SpringBootApplication
public class Service1Application {

    public static void main(String[] args) {
        SpringApplication.run(Service1Application.class, args);
    }

    @Bean
    public RestTemplate restTemplate() {
        return new RestTemplate();

    @Bean
    JaegerReportAppender customLoggingReporter() {
        return new JaegerReportAppender();
    }

推荐答案

不幸的是，reporter 接口用于报告 FINISHED spans，它是在 JaegerSpan.finish 上调用的.我想这就是它没有出现在日志中的原因.

Unfortunatelly, the reporter interface is used to report FINISHED spans, it is invoked on JaegerSpan.finish. I presume this is why it does not appear in logs.
