How to turn off debug log messages in spring boot

Question

I read in spring boot docs (https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-logging.html)

you can also specify debug=true in your application.properties"

So I guess I can turn off the debug logs by adding debug=false in application.properties. I did it but unfortunately, it didn't work. Then I read in the same doc

The logging system is initialized early in the application lifecycle and as such logging properties will not be found in property files loaded via @PropertySource annotations"

and

"Since logging is initialized before the ApplicationContext is created, it isn’t possible to control logging from @PropertySources in Spring @Configuration files"

and

"When possible we recommend that you use the -spring variants for your logging configuration" so I added a file named log4j-spring.properties in src/main/resources.

In such file, I added debug=false (only this line and nothing else) but I am still seeing all "current date" [main] DEBUG ... messages. So, my question is how can I turn off the debug messages in my Spring Boot Application as I will deploy to the application to production. Is there a recommended way to reach this via maven?

The two main methods: 1)By using AnnotationConfigApplicationContext:

public class DemoAppNoBoot {        public static void main(String[] args) {               AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(                            BatchConfiguration.class);               JobLauncher jobLauncher = (JobLauncher) context.getBean("jobLauncher");               Job job = (Job) context.getBean("job");                try {                      JobExecution execution = jobLauncher.run(job, new JobParameters());               } catch (Exception e) {                      e.printStackTrace();               }        } }

Answer 1

In application.properties you can add ‘logging.level.*=LEVEL’ where ‘LEVEL’ is one of TRACE, DEBUG, INFO, WARN, ERROR, FATAL, OFF. * is responsible for package/class.

For example

logging.level.root=WARN logging.level.org.springframework.web=DEBUG logging.level.org.hibernate=ERROR 

This means that root logger has WARN level. org.springframework.web is on DEBUG level, but all hibernates files are logged only ERROR.

In your case you must set logging.level.root on one of level from INFO, WARN, ERROR,FATAL or OFF to turn off all logging.

See https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-logging.html#boot-features-custom-log-levels

Answer 2

While using Spring Rest Docs with SpringMockMVC with testLogging.showStandardStreams set to true in Gradle, Spring cluttered the console with info & debug logs. I had to use Mkyong's solution where in a logback-test.xml in src/test/resources needs to be created on top of the chosen solution here. Use log-level OFF, ERROR, WARN, DEBUG

logback-test.xml

<?xml version="1.0" encoding="UTF-8"?> <configuration>     <include resource="org/springframework/boot/logging/logback/base.xml" />     <logger name="org.springframework" level="ERROR"/> </configuration>
