It was necessary to change from logback to log4j, I modified pom for this:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter</artifactId>
    <exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-logging</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-log4j</artifactId>
</dependency>

And 'log4j.properties' file was added:

log4j.rootLogger=INFO,Console

log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.Target=System.out
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.conversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} %-5p - %m%n

But in result, there are different logs. With logback I have something like this:

2022-11-15 18:43:05.819  INFO 13700 --- [           main] en.main.com.Application                   : Starting Application using Java 11.0.14 on '' with PID 13700
2022-11-15 18:43:06.710  INFO 13700 --- [           main] o.s.cloud.context.scope.GenericScope      : BeanFactory id=eb6a152f-721c-3012-b9ce-880d2bbbe06c

And after log4j:

2022-11-15 18:38:00,817 INFO  - Initializing ProtocolHandler ["http-nio-8081"]
2022-11-15 18:38:00,818 INFO  - Starting service [Tomcat]

2022-11-15 18:38:03,397 INFO  - HikariPool-2 - Start completed.

I can't understand why a part of useful information is missing. Also tried to display some transactions info, by adding

log4j.logger.org.springframework.jdbc.datasource.DataSourceTransactionManager=DEBUG

but there is no result.

    It's following the "conversionPattern" that you specified in the config. If you want it to be different, then change the pattern. – Michael Nov 15 '22 at 17:40
  • @Michael thx for your comment, I tried to change the "conversionPattern" and even delete it, but I still can't see messages in the log about the PID and the start time of the application, as it was in the logback. – Ivan Nov 16 '22 at 06:02
  • See https://stackoverflow.com/questions/4622252/how-to-add-the-process-id-to-a-log4j-log-file – grekier Nov 16 '22 at 08:42
  • @grekier in that topic, the message format is also considered, in my case some information has completely disappeared, i.e. there are no whole messages – Ivan Nov 16 '22 at 09:07
