logback 自定義 MessageConvert 轉換log參數

public class ExtendMessageConverter extends MessageConverter {
    @Override
    public String convert(ILoggingEvent event) {
        return MessageFormatter.arrayFormat(event.getMessage(), Stream.of(event.getArgumentArray()).map(this::cvt).toArray()).getMessage();
    }

    private String cvt(Object o) {
        return String.format("convert{%s}", o);
    }
}
