在 Sleuth 日志中看不到 TraceId 和 spanId

Question

我已经开始学习 Sleuth，但我陷入了日志配置。

\n

我有这个配置：

\n

    <?xml version="1.0" encoding="UTF-8"?>\n<configuration>\n    <include resource="org/springframework/boot/logging/logback/defaults.xml"/>\n    \xe2\x80\x8b\n    <springProperty scope="context" name="springAppName" source="spring.application.name"/>\n    <!-- Example for logging into the build folder of your project -->\n    <property name="LOG_FILE" value="C://tmp//test"/>\xe2\x80\x8b\n\n    <property name="CONSOLE_LOG_PATTERN"\n              value="%clr(%d{yyyy-MM-dd HH:mm:ss.SSS}){faint} %clr(${LOG_LEVEL_PATTERN:-%5p}) %clr([${springAppName:-},%X{X-B3-TraceId:-},%X{X-B3-SpanId:-},%X{X-Span-Export:-}]){yellow} %clr(${PID:- }){magenta} %clr(---){faint} %clr([%15.15t]){faint} %clr(%-40.40logger{39}){cyan} %clr(:){faint} %m%n${LOG_EXCEPTION_CONVERSION_WORD:-%wEx}"/>\n\n    <!-- Appender to log to console -->\n    <appender name="console" class="ch.qos.logback.core.ConsoleAppender">\n        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">\n            <level>INFO</level>\n        </filter>\n        <encoder>\n            <pattern>${CONSOLE_LOG_PATTERN}</pattern>\n            <charset>utf8</charset>\n        </encoder>\n    </appender>\n    \xe2\x80\x8b\n    <!-- Appender to log to file in a JSON format -->\n    <appender name="logstash" class="ch.qos.logback.core.rolling.RollingFileAppender">\n        <file>${LOG_FILE}.json</file>\n        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">\n            <fileNamePattern>${LOG_FILE}.json.%d{yyyy-MM-dd}.gz</fileNamePattern>\n            <maxHistory>7</maxHistory>\n        </rollingPolicy>\n        <encoder class="net.logstash.logback.encoder.LoggingEventCompositeJsonEncoder">\n            <providers>\n                <timestamp>\n                    <timeZone>UTC</timeZone>\n                </timestamp>\n                <pattern>\n                    <omitEmptyFields>true</omitEmptyFields>\n                    <pattern>\n                        {\n                        "severity": "%level",\n                        "service": "${springAppName:-}",\n                        "trace": "%X{X-B3-TraceId:-}",\n                        "span": "%X{X-B3-SpanId:-}",\n                        "parent": "%X{X-B3-ParentSpanId:-}",\n                        "exportable": "%X{X-Span-Export:-}",\n                        "baggage": "%X{key:-}",\n                        "pid": "${PID:-}",\n                        "thread": "%thread",\n                        "class": "%logger{40}",\n                        "rest": "%message"\n                        }\n                    </pattern>\n                </pattern>\n            </providers>\n        </encoder>\n    </appender>\n    \xe2\x80\x8b\n    <root level="INFO">\n        <appender-ref ref="console"/>\n        <appender-ref ref="logstash"/>\n    </root>\n</configuration>\n

\n

但是当我检查文件时，我缺少traceId 和spanId。这是示例：

\n

{"@timestamp":"2021-01-12T17:31:51.861Z","severity":"INFO","service":"kz-report","pid":"25248","thread":"http-nio-9089-exec-1","class":"c.k.r.s.impl.ExaminationServiceImpl","rest":"User with ID 1 and name Nemanja is fetching examination by ID 2"}\n

\n

这是 pom.xml 的片段

\n

        <dependency>\n            <groupId>org.springframework.cloud</groupId>\n            <artifactId>spring-cloud-starter-zipkin</artifactId>\n        </dependency>\n    \n        <dependency>\n            <groupId>net.logstash.logback</groupId>\n            <artifactId>logstash-logback-encoder</artifactId>\n            <version>6.6</version>\n        </dependency>\n

\n

不知道如何继续这里，我一直在阅读文档和堆栈溢出帖子，但仍然找不到任何答案。

\n

提前致谢。

您好，“%X{X-B3-TraceId:-}”这样的符号不再起作用，您应该使用如下所示的符号：

 <appender name="logstash" class="ch.qos.logback.core.rolling.RollingFileAppender">
            <file>${LOG_FILE}.json</file>
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                <fileNamePattern>${LOG_FILE}.json.%d{yyyy-MM-dd}.gz</fileNamePattern>
                <maxHistory>7</maxHistory>
            </rollingPolicy>
            <encoder class="net.logstash.logback.encoder.LoggingEventCompositeJsonEncoder">
                <providers>
                    <timestamp>
                        <timeZone>UTC</timeZone>
                    </timestamp>
                    <pattern>
                        <pattern>
                            {
                            "timestamp": "@timestamp",
                            "severity": "%level",
                            "service": "${springAppName:-}",
                            "trace": "%X{traceId:-}",
                            "span": "%X{spanId:-}",
                            "pid": "${PID:-}",
                            "thread": "%thread",
                            "class": "%logger{40}",
                            "rest": "%message"
                            }
                        </pattern>
                    </pattern>
                </providers>
            </encoder>
        </appender>
