Spring Boot enable http requests logging (access logs)

In Spring Boot 1.5.1 the properties mentioned by Dave Syer no longer works, instead they're renamed into:

server.tomcat.basedir=target/tomcat-logs
server.tomcat.accesslog.enabled=true
server.tomcat.accesslog.pattern=%t %a "%r" %s (%D ms)

Using the configuration above, if running the project via its root directory the log will be available at target/tomcat-logs/log/access_log.*

With Spring Boot 2.X, if you want to manage Access logs, add these lines to your application.yml file:

server:
  tomcat:
    basedir: /home/tmp
    accesslog:
      enabled: true

It will create a folder named logs in the basedir you defined (/home/tmp here) containing the access log files.

If you want to have access logs in the console do like that:

server:
  tomcat:
    accesslog:
      enabled: true
      directory: /dev
      prefix: stdout
      buffered: false
      suffix:
      file-date-format:

It will rediect logs to /dev/stdout

More informations: https://community.pivotal.io/s/article/how-to-configure-access-log-entries-for-a-spring-boot-app?language=en_US

Here it goes a way to have them displayed in console or whatever file you choose. Declare Tomcat's RequestDumperFilter in any @Configuration class:

@Bean
public FilterRegistrationBean requestDumperFilter() {
    FilterRegistrationBean registration = new FilterRegistrationBean();
    Filter requestDumperFilter = new RequestDumperFilter();
    registration.setFilter(requestDumperFilter);
    registration.addUrlPatterns("/*");
    return registration;
}

And that's the output:

Then manage it as any standard Spring Boot log.

Try

server.tomcat.accessLogEnabled=true
server.tomcat.accessLogPattern=%a asdasd

and look in /tmp/tomcat.<random>.<port>/logs for the output files. Set server.tomcat.basedir property to change the directory.
