Spring boot logging into multiple files

Question

Is there any way I can configure spring boot logging to multiple files/console based on the configuration? i.e Some of the log statements should write into an audit file and normal log statements should go to console/normal log file.

Below is the code I have tried on spring boot example application.

logback-spring.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <include resource="org/springframework/boot/logging/logback/base.xml"/>
    <logger name="file" level="DEBUG" additivity="false">
        <appender-ref ref="FILE" />
    </logger>
    <logger name="org.hello" level="ERROR" additivity="false">
        <appender-ref ref="CONSOLE" />
    </logger>
</configuration>

Below is the application.properties entries

logging.level.org.springframework.web=INFO
logging.file=logs/spring-boot-logging.log

Below the HelloController

@RestController
public class HelloController {

Logger logger = LoggerFactory.getLogger(HelloController.class);

    Logger logger1 = LoggerFactory.getLogger("file");

    @RequestMapping("/")
    public String index() {

        logger.info("My Log test");
        logger1.info("My Audit test");


        return "Greetings from Spring Boot!";
    }

}

Can someone please help? Did anyone face similar situation?

Thanks a lot

Standard logback example, two files with different packages going to different files :

<configuration>

  <appender name="FILE1" class="ch.qos.logback.core.FileAppender">
    <file>myApp1.log</file>
    <encoder>
      <pattern>%date %level [%thread] %logger{10} [%file:%line] %msg%n</pattern>
    </encoder>
  </appender>

  <appender name="FILE2" class="ch.qos.logback.core.FileAppender">
    <file>myApp1.log</file>
    <encoder>
      <pattern>%date %level [%thread] %logger{10} [%file:%line] %msg%n</pattern>
    </encoder>
  </appender>

  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
      <pattern>%msg%n</pattern>
    </encoder>
  </appender>

  <logger name="com.package1.foo" level="DEBUG">
    <appender-ref ref="FILE1" />
  </logger>

  <logger name="com.package2.bar" level="DEBUG">
    <appender-ref ref="FILE2" />
  </logger>

  <root level="debug">
    <appender-ref ref="STDOUT" />
  </root>
</configuration>
