解决毫秒级日志乱续问题,让logback输出microseconds(微秒)

filebeat推送给o2的毫秒级顺序是乱的
当然这是一个假的microseconds,linux并不支持这个时间级别

• 编写一个微秒转换器

public class LogbackMicrosecondsConverter extends ClassicConverter {
    private final long start  = System.nanoTime();

    @Override
    public String convert(ILoggingEvent iLoggingEvent) {
        long now = System.nanoTime();
        var diffMicroseconds = (now - start)/1000;
        var diffStr = String.valueOf(diffMicroseconds);
        return diffStr.substring(diffStr.length()-3);
    }
}

• 在xml里配置

	<conversionRule conversionWord="microseconds"
					converterClass="xxx.xxx.LogbackMicrosecondsConverter" />
	<property name="CONSOLE_LOG_PATTERN"
		value="%d{yyyy-MM-dd HH:mm:ss.SSS}%-3microseconds />

• 虽然这是一个假的微秒,但足以解决日志乱续的问题
