Question

我在spring引导属性中定义spring.application.name，在logback.xml中写了$ {spring.application.name:-}，但显示为spring.application.name_IS_UNDEFINED。你知道为什么吗？

如何在xml中使用类似“主机名”的字词？

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <layout class="ch.qos.logback.classic.PatternLayout">
            <Pattern>%5p [${spring.zipkin.service.name:${spring.application.name:-}},%X{X-B3-TraceId:-},%X{X-B3-SpanId:-},%X{X-Span-Export:-}] aaaaaaaaaaaaaaaaaa %d{HH:mm} %-5level %logger{36} - %msg%n</Pattern>
        </layout>
    </appender>

    <logger name="example.logback.level.grandparents" level="TRACE"/>
    <logger name="example.logback.level.grandparents.parents.children" level="INFO"/>
    <root level="DEBUG">
        <appender-ref ref="STDOUT" />
    </root>
</configuration>

我的“ application.properties”

spring.application.name=elasticsearch-monitering
spring.kafka.consumer.group-id=foo
spring.kafka.consumer.auto-offset-reset=earliest

spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp

#elasticsearch server info
server.elasticsearch.host=my.i.p
server.elasticsearch.port=9200

请参见以下示例：

application.properties

logback.appender.FILE-AUDIT.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss, GMT+8} - %msg%n

logback-spring.xml

  <?xml version="1.0" encoding="UTF-8"?>
       <configuration>
             ..........
          <springProperty name="fileAppenderPattern" source="logback.appender.FILE-AUDIT.ConversionPattern"/>
             ..........
          <include resource="logback-appender-file.xml"/>
            ..........
      </configuration>

logback-appender-文件

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <layout class="ch.qos.logback.classic.PatternLayout">
            <Pattern>${fileAppenderPattern}</Pattern>
        </layout>
    </appender>

    <logger name="example.logback.level.grandparents" level="TRACE"/>
    <logger name="example.logback.level.grandparents.parents.children" level="INFO"/>
    <root level="DEBUG">
        <appender-ref ref="STDOUT" />
    </root>
</configuration>
