SpringBoot2中如何实现按API接口路径动态保存Log4j2日志？

<configuration monitorInterval="5" status="debug">
  <appenders>
    <routing name="routing">
      <routes pattern="${ctx:routingkey}">
        <route>
          <rollingFile filename="./logs/${ctx:routingkey}/${date:yyyy-mm-dd}.log"
                       filePattern="./logs/${date:yyyy-mm}/${ctx:routingkey}-%d{yyyy-mm-dd}-%i.log.gz"
                       name="rolling-${ctx:routingkey}">
            <PatternLayout pattern="%d{iso8601} [%t] %p %c{3} - %m%n"/>
            <Policies>
              <TimeBasedTriggeringPolicy interval="1" modulate="true"/>
              <SizeBasedTriggeringPolicy size="10MB"/>
            </Policies>
          </rollingFile>
        </route>
      </routes>
    </routing>
  </appenders>
  <loggers>
    <root level="info">
      <appender-ref ref="routing"/>
    </root>
  </loggers>
</configuration>

public class Log4j2Interceptor implements HandlerInterceptor {
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        String apiPath = request.getRequestURI();
        ThreadContext.put("routingkey", apiPath);
        return true;
    }

    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
        ThreadContext.remove("routingkey");
    }
}
