系统中有自己的Netty服务器，同时指定Dubbo用Netty，然后LoggingHandler就没法用了。下面的代码回导致我的Netty服务器无法使用Netty自带的日志体系。如果我强制自己的Netty服务器晚于Dubbo加载，那么Dubbo也是无法使用到DubboLogger的。
```
public class NettyHelper {
public static void setNettyLoggerFactory() {
InternalLoggerFactory factory = InternalLoggerFactory.getDefaultFactory();
if (factory == null || !(factory instanceof DubboLoggerFactory)) {
InternalLoggerFactory.setDefaultFactory(new DubboLoggerFactory());
}
}
```

System is TCP server using Netty4, and Dubbo is specified to use Netty4. When I add LoggingHandler to ChannelPipeline of my System, The log is not expected.
Like this:
I tracked the code and found the Logger is `com.alibaba.dubbo.remoting.transport.netty4.logging.NettyHelper.DubboLogger` instead of `io.netty.util.internal.logging.Slf4JLogger`. DubboLogger added other content arount the original log. The NeetyHelper replace the InternalLoggerFactory when Dubbo loading, like the code block above shows.
# By the way.
My system build by Spring Boot, use default logging framework which is Slf4j + Logback.
Dubbo's logger is not extend default logger, but replace it.
