Review comment:
```
public class MyHandler implements Handler {
private static final Logger LOGGER =
LoggerFactory.getLogger(MyHandler.class);
public static final String SPLITPARAM_RESPONSE_USER_SUFFIX = "(modified by
MyHandler)";
@Override
public void handle(Invocation invocation, AsyncResponse asyncResp) throws
Exception {
LOGGER.info("before");
invocation.next(response -> {
LOGGER.info("after");
});
}
}
```
You can find many Handler implementations in servicecomb-java-chassis
project.
