How do you tell Spring Boot to send the embedded Tomcat's access logs to stdout?

Question

In a standalone Spring Boot web application (executable jar), how do you tell Spring Boot that we want the embedded Tomcat instance\'s HTTP access logs to be sent to stdout?

Answer 1

JohanB's solution works, but if you don't want to write code, someone did it better and wrapped Server access logs in a nice Spring Boot starter. It covers Tomcat, Jetty and Undertow.

Just add the dependency :

    net.rakugakibox.spring.boot
    logback-access-spring-boot-starter
    2.7.1

And a logback-access.xml file at the classpath root :

    
        
            common
        
    
    

and the access logs are printed to stdout :

127.0.0.1 - - [08/févr./2019:11:23:30 +0100] "GET /password HTTP/1.1" 200 32

At this point you will need to create the TeeFilter Bean on your own if you want to print the full HTTP request & response for debugging.
