How to turn off debug log messages in spring boot
<p>I read in spring boot docs (<a href="https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-logging.html" rel="noreferrer">https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-logging.html</a>)</p>
<blockquote>
<p>you can also specify debug=true in your application.properties&quot;</p>
</blockquote>
<p>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</p>
<blockquote>
<p>The logging system is initialized early in the application lifecycle and as such logging properties will not be found in property files loaded via <code>@PropertySource</code> annotations&quot;</p>
</blockquote>
<p>and</p>
<blockquote>
<p>&quot;Since logging is initialized before the <code>ApplicationContext</code> is created, it isn’t possible to control logging from <code>@PropertySources</code> in Spring <code>@Configuration</code> files&quot;</p>
</blockquote>
<p>and</p>
<blockquote>
<p>&quot;When possible we recommend that you use the -spring variants for your logging configuration&quot; so I added a file named <code>log4j-spring.properties</code> in <code>src/main/resources</code>.</p>
</blockquote>
<p>In such file, I added <code>debug=false</code> (only this line and nothing else) but I am still seeing all &quot;current date&quot; [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?</p>

<p>The two main methods:
1)By using AnnotationConfigApplicationContext:</p>
<pre><code>public class DemoAppNoBoot {
       public static void main(String[] args) {
              AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(
                           BatchConfiguration.class);
              JobLauncher jobLauncher = (JobLauncher) context.getBean(&quot;jobLauncher&quot;);
              Job job = (Job) context.getBean(&quot;job&quot;);
               try {
                     JobExecution execution = jobLauncher.run(job, new JobParameters());
              } catch (Exception e) {
                     e.printStackTrace();
              }
       }
}
