假设你有这种 logback-spring.xml 使用占位符（仅示例）：

<configuration>
    <include resource="org/springframework/boot/logging/logback/base.xml"/>
    <include resource="org/springframework/boot/logging/logback/defaults.xml"/>
    <include resource="org/springframework/boot/logging/logback/console-appender.xml"/>
    <springProperty name="appName" source="spring.application.name" scope="context"/>
    <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
          <encoder>
             <pattern>${appName}</pattern>
        </encoder>
    </appender>
    <root level="INFO">
        <appender-ref ref="CONSOLE"/>
    </root>
</configuration>

如果你有这个文件在里面的话，这个工作就完美了 resources 或者通过 logging.level 财产。
但是，当我尝试通过configmap在openshift中绑定此文件时，会发生以下错误：

ERROR org.springframework.boot.SpringApplication - Application run failed
java.lang.IllegalArgumentException: Could not resolve placeholder 'appName' in value "<configuration>
    <include resource="org/springframework/boot/logging/logback/base.xml"/>
    <include resource="org/springframework/boot/logging/logback/defaults.xml"/>
    <include resource="org/springframework/boot/logging/logback/console-appender.xml"/>
    <springProperty name="appName" source="spring.application.name" scope="context"/>
    <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
          <encoder>
             <pattern>${appName}</pattern>
        </encoder>
    </appender>
    <root level="INFO">
        <appender-ref ref="CONSOLE"/>
    </root>
</configuration>

openshift中的configmap如下所示：

kind: ConfigMap
apiVersion: v1
metadata:

data:
  logback-spring.xml: |
    <configuration>
        <include resource="org/springframework/boot/logging/logback/base.xml"/>
        <include resource="org/springframework/boot/logging/logback/defaults.xml"/>
        <include resource="org/springframework/boot/logging/logback/console-appender.xml"/>
        <springProperty name="appName" source="spring.application.name" scope="context"/>
        <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
              <encoder>
                 <pattern>${appName}</pattern>
            </encoder>
        </appender>
        <root level="INFO">
            <appender-ref ref="CONSOLE"/>
        </root>
    </configuration>

我在部署配置的“环境”部分以以下方式绑定该配置：

我做错什么了？提前谢谢！

Java spring spring-boot logback openshift

而不是

<springProperty name="appName" source="spring.application.name" scope="context"/>

试试这个-

<springProperty name="appName" source="${bundle:application:spring.application.name}" scope="context"/>

如果您必须从configmap中读取某些内容作为属性，可以尝试以下操作-

<springProperty name="logLevel" source="${env:LOG_LEVEL:-INFO}" scope="context"/>

如果该属性不在配置Map中，我提供了一个默认值。

我设法使它与卷一起工作。以下是部署配置的一部分：

spec:
  volumes:
    - name: logback-configmap-volume
      configMap:
        name: logback-configmap
  containers:
    - name: xxx
      volumeMounts:
        - name: logback-configmap-volume
          mountPath: /config
      env:
        - name: logging.config
          value: /config/logback-spring.xml

请告诉我是否可以不使用卷来实现相同的结果。
