Spring Boot 3.3.0 Native debug=true in application.properties No effect

[syedyusufh]

I need to debug my Spring Boot v3.3.0 native application built using mvn package -P <native-profile> as it is failing to load application properties from AWS parameter store which was otherwise working fine till Spring Boot v3.2.5

So, have added debug=true in application.properties and expected to see additional information on the config failure reported via org.springframework.boot.diagnostics.LoggingFailureAnalysisReporter, but no effect

Debug logs from org.springframework.boot.diagnostics.LoggingFailureAnalysisReporter aren't available for the native image.

Without knowing what's happening when you start the application, it's not clear if LoggingFailureAnalysisReporter will have been called. For that to happen, an exception for which failure analysis is performed successfully would have to be thrown when the application is started.

If you would like us to spend some more time investigating, please spend some time providing a complete yet minimal sample that reproduces the problem. You can share it with us by pushing it to a separate repository on GitHub or by zipping it up and attaching it to this issue.

Thanks for the quick revert @wilkinsona

I am referring to the below class which is reporting the startup failure related to config location citing AWS parameterstore. Inorder to see the actual root cause, I need to have the debug logging enabled for my native image. Have tried with debug=true in application.properties which does not have any effect. Please correct if I'm wrong. Thanks

public final class LoggingFailureAnalysisReporter implements FailureAnalysisReporter {

	private static final Log logger = LogFactory.getLog(LoggingFailureAnalysisReporter.class);

	@Override
	public void report(FailureAnalysis failureAnalysis) {
		if (logger.isDebugEnabled()) {
			logger.debug("Application failed to start due to an exception", failureAnalysis.getCause());
		}
		if (logger.isErrorEnabled()) {
			logger.error(buildMessage(failureAnalysis));
		}
	}

	private String buildMessage(FailureAnalysis failureAnalysis) {
		StringBuilder builder = new StringBuilder();
		builder.append(String.format("%n%n"));
		builder.append(String.format("***************************%n"));
		builder.append(String.format("APPLICATION FAILED TO START%n"));
		builder.append(String.format("***************************%n%n"));
		builder.append(String.format("Description:%n%n"));
		builder.append(String.format("%s%n", failureAnalysis.getDescription()));
		if (StringUtils.hasText(failureAnalysis.getAction())) {
			builder.append(String.format("%nAction:%n%n"));
			builder.append(String.format("%s%n", failureAnalysis.getAction()));
		}
		return builder.toString();
	}

As I said above, without knowing what the failure is, I don't know if it will have been analyzed. Please provide the requested sample. We can then investigate further.

Please check the below sample application with the mentioned startup failure logs. Need to enable debug logs as to see the actual root cause. Thanks

Sample Application

20:12:07.297 [restartedMain] ERROR org.springframework.boot.diagnostics.LoggingFailureAnalysisReporter -- 

***************************
APPLICATION FAILED TO START
***************************

Description:

Config data location 'aws-parameterstore:/config/config-failure-debug_dev/' does not exist

Action:

Check that the value 'aws-parameterstore:/config/config-failure-debug_dev/' at class path resource [application.properties] - 4:23 is correct, or prefix it with 'optional:'

@Override
public void report(FailureAnalysis failureAnalysis) {
	if (logger.isDebugEnabled()) {
		logger.debug("Application failed to start due to an exception", failureAnalysis.getCause());
	}

This is quite similar to #32120.

The problem we have here is that we can't load the application.properties file so we throw an exception. That exception prevents us from using the debug: true property in the file.

I'm not sure that there is much we can do to improve the situation unfortunately.
