How to configure location and name of tomcat access log in spring-boot?

Question

I have a spring-boot application with the following configuration in application.yml

server: contextPath: /rti tomcat: access-log-enabled: true access-log-pattern: "%h %l %u %t \"%r\" %s %b %D" basedir: tomcat 

You will be asked to create an access log tomcat / logs / access_log.2015-02-02.txt.

I would like to be able to configure where the access log is created and what it is called; but after a long search I begin to think that this is impossible. Does anyone know how to achieve this?

Application logging works fine using logging and configuration in logback.xml

You can use the EmbeddedServletContainerCustomizer interface to add a fully custom valve to your built-in tomcat. Here is what works for me:

 @Configuration public class WebConfig extends WebMvcConfigurerAdapter implements EmbeddedServletContainerCustomizer { @Override public void customize(ConfigurableEmbeddedServletContainer container) { if (container instanceof TomcatEmbeddedServletContainerFactory) { TomcatEmbeddedServletContainerFactory factory = (TomcatEmbeddedServletContainerFactory) container; AccessLogValve accessLogValve = new AccessLogValve(); accessLogValve.setDirectory("/var/log/test"); accessLogValve.setPattern("common"); accessLogValve.setSuffix(".log"); factory.addContextValves(accessLogValve); } else { logger.error("WARNING! this customizer does not support your configured container"); } } }

Configuration in application.yml ( https://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html ):

 server.tomcat.accesslog: # Enable access log: enabled: true # Directory in which log files are created. Can be relative to the tomcat base dir or absolute: directory: /var/log/test # Format pattern for access logs: # https://tomcat.apache.org/tomcat-8.0-doc/config/valve.html#Access_Log_Valve pattern: '%h %l %u %t "%r" %s %b %D' # Log file name suffix: suffix: .log
