PropertySourceBootstrapConfiguration not reinitializeLoggingSystem if git properties not contains logging prefix attribute

[gudegg]

if my git properties

custom.logging.logpath=/usr/xxx

private void reinitializeLoggingSystem(ConfigurableEnvironment environment,
			String oldLogConfig, LogFile oldLogFile) {
		Map<String, Object> props = Binder.get(environment)
				.bind("logging", Bindable.mapOf(String.class, Object.class)).orElseGet(Collections::emptyMap);
              //If the custom key such as ‘custom.logging.logpath’ will not continue to call
		if (!props.isEmpty()) {
			String logConfig = environment.resolvePlaceholders("${logging.config:}");
			LogFile logFile = LogFile.get(environment);
			LoggingSystem system = LoggingSystem
					.get(LoggingSystem.class.getClassLoader());
			try {
				ResourceUtils.getURL(logConfig).openStream().close();
				// Three step initialization that accounts for the clean up of the logging
				// context before initialization. Spring Boot doesn't initialize a logging
				// system that hasn't had this sequence applied (since 1.4.1).
				system.cleanUp();
				system.beforeInitialize();
				system.initialize(new LoggingInitializationContext(environment),
						logConfig, logFile);
			}
			catch (Exception ex) {
				PropertySourceBootstrapConfiguration.logger
						.warn("Logging config file location '" + logConfig
								+ "' cannot be opened and will be ignored");
			}
		}
	}

You haven't provided almost any required information necessary to help you. Please provide a sample that replicates the problem

I want to replace the logback.xml property with spring cloud config. git repository,but not work,get defaultValue.

<springProperty name="LOG_PATH" scope="context" source="custom.logging.logpath" defaultValue="/opt/logs"/>

[marcingrzejszczak]

Can you provide a full sample that replicates the problem?

Without setting some kind of property that specifies the custom logging prefix I am not sure how we could identify the correct property.

[gudegg]

can ignore the prefix every time it is refreshed, but this can be a bad practice

The team decided to add a note to the documentation about this limitation.
