本文整理了Java中org.slf4j.MDC.get()方法的一些代码示例，展示了MDC.get()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。MDC.get()方法的具体详情如下：
包路径：org.slf4j.MDC
类名称：MDC
方法名：get

MDC.get介绍

[英]Get the diagnostic context identified by the key parameter. The key parameter cannot be null.

This method delegates all work to the MDC of the underlying logging system.
[中]获取由key参数标识的诊断上下文。key参数不能为空。
此方法将所有工作委托给底层日志系统的MDC。

@Override
public FilterReply decide(Marker marker, Logger logger, Level level, String format, Object[] params, Throwable t) {
  if (MDCKey == null) {
    return FilterReply.NEUTRAL;
  }
  String value = MDC.get(MDCKey);
  if (this.value.equals(value)) {
    return onMatch;
  }
  return onMismatch;
}

  assertNotNull(MDC.get("spanId"));
