如何以 [traceId, spanId ] 格式获取 log4j2 中的 trace id 和 span id?

How to get trace id and span id in the log4j2, in the format [traceId, spanId ]?

如何在 log4j2 中获取跟踪 ID 和跨度 ID,而不是在 [traceId, spanId ] 中?

预期输出: [APPNAME,5a59b2372d9a3814,5a59b2372d9a3814]

实际输出: [logLevel=ERROR] -- 2021-01-21 11:30:32,489 +0530 -- http-nio-8080-exec-1 com.springboot.test.aspect.MyAspect -- asnId= - message="Logging key:", traceId=f19556b82d98bf86, executionTimeSeconds=23

我的 log4j2:尝试添加下面的评论 属性 但在日志中没有看到跟踪 ID


        <Property name="LOG_PATTERN">[logLevel=%-5p] -- %d %d{Z} -- %t %c -- asnId=%X{ASN} - %m%n</Property>
        <property name="log.level">${bundle:DEV:logLevel}</property>
         <!--  <property name="rolling.file.encoder.pattern"
              value="%d{yyyy-MM-dd'T'HH:mm:ss.SSSZ} %-5level : loggerName=&quot;%logger{36}&quot; threadName=&quot;%thread&quot;  appName=&quot;${springAppName:-}&quot; trace=&quot;%X{X-B3-TraceId:-}&quot; span=&quot;%X{X-B3-SpanId:-}&quot; spanName=&quot;%X{X-Span-Name:-}&quot; parent=&quot;%X{X-B3-ParentSpanId:-}&quot; exportable=&quot;%X{X-Span-Export:-}&quot; pid=&quot;${PID:-}&quot; txnId=&quot;%X{txnId}&quot; %msg%n"/> -->
         <!--   <property name="PATTERN" value="%h %l %u [%date{dd/MMM/yyyy:HH:mm:ss.SSS}] &quot;%r&quot; %s %b &quot; &quot;%i{User-Agent}&quot; [trace=%responseHeader{X-B3-TraceId},span=%i{X-B3-SpanId}] %D"/> -->
    </Properties>

看点class:

在我的方面的日志中 class 但是我可以看到跟踪 ID

public class MyAspect {

    private final static Logger logger = LogManager.getLogger(MyAspect.class);
    long startTime = new Date().getTime();
    
    @Autowired
    Tracer tracer;

      @Around("allControllerMethods() && args(..,@annotation(org.springframework...RequestBody) requestBody) ")
      public Object controllerEvents(ProceedingJoinPoint jp, Object requestBody) throws Throwable {
            
         ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
             HttpServletRequest request = attributes.getRequest();
             MethodSignature signature = (MethodSignature) jp.getSignature();
              Method method = signature.getMethod();
              Object resObject = jp.proceed();
         
              logger.error("traceId", tracer.currentSpan().context().traceIdString());

        }
    }

pom :

<dependency>
            <groupId>io.zipkin.brave</groupId>
            <artifactId>brave</artifactId>
            <version>5.12.6</version>
        </dependency>

            <version>1.4.2.RELEASE</version>
        </dependency>

配置处理器:

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

请注意,在我没有使用 log4j 的测试项目中,它符合预期。

我可以通过进行以下更改来获取 traceId 和 spanId : 1)添加到log4j

  <Property name="LOG_PATTERN">[logLevel=%-5p]-- [%X{traceId}/%X{spanId}] -- %d %d{Z} -- %t %c - %m%n</Property>

2) 添加属性 :

request.logging.shouldLog=true

3)添加

    @Value("${request.logging.shouldLog}")
    private boolean shouldLog;
    
//    @Override
    protected boolean shouldLog(HttpServletRequest request) {
        return shouldLog;
    }
