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

-

in standalone spring boot web application (executable jar), how tell spring boot want embedded tomcat instance's http access logs sent stdout?

if use logback, can use logback-access this.

add dependency ch.qos.logback:logback-access

optional javaconfig add teefilter (request & response logging):

@bean(name = "teefilter") public filter teefilter() {     return new ch.qos.logback.access.servlet.teefilter(); }

javaconfig embedded tomcat:

@bean public embeddedservletcontainerfactory servletcontainer() {     tomcatembeddedservletcontainerfactory tomcat = new tomcatembeddedservletcontainerfactory();      logbackvalve logbackvalve = new logbackvalve();      // point logback-access.xml     logbackvalve.setfilename("src/main/resources/logback-access.xml");      tomcat.addcontextvalves(logbackvalve);      return tomcat; }

contents logback-access.xml

<configuration>   <appender name="stdout" class="ch.qos.logback.core.consoleappender">     <encoder>       <pattern>combined</pattern>       <pattern>%fullrequest%n%n%fullresponse</pattern>     </encoder>   </appender>    <appender-ref ref="stdout" />  </configuration>
