本文整理了Java中org.slf4j.Marker类的一些代码示例，展示了Marker类的具体用法。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。Marker类的具体详情如下：
包路径：org.slf4j.Marker
类名称：Marker

Marker介绍

[英]Markers are named objects used to enrich log statements. Conforming logging system Implementations of SLF4J determine how information conveyed by markers are used, if at all. In particular, many conforming logging systems ignore marker data.

Markers can contain references to other markers, which in turn may contain references of their own.
[中]标记是用于充实日志语句的命名对象。SLF4J的一致性记录系统实现决定了如何使用标记传递的信息（如果有的话）。特别是，许多符合要求的测井系统忽略了标记数据。
标记可以包含对其他标记的引用，而其他标记又可以包含自己的引用。

代码示例

代码示例来源：origin: org.apache.logging.log4j/log4j-slf4j-impl

private static org.apache.logging.log4j.Marker convertMarker(final Marker original,
                               final Collection<Marker> visited) {
  final org.apache.logging.log4j.Marker marker = MarkerManager.getMarker(original.getName());
  if (original.hasReferences()) {
    final Iterator<Marker> it = original.iterator();
    while (it.hasNext()) {
      final Marker next = it.next();
      if (visited.contains(next)) {
        LOGGER.warn("Found a cycle in Marker [{}]. Cycle will be broken.", next.getName());
      } else {
        visited.add(next);
        marker.addParents(convertMarker(next, visited));
      }
    }
  }
  return marker;
}

代码示例来源：origin: redisson/redisson

public void add(Marker reference) {
  if (reference == null) {
    throw new IllegalArgumentException("A null value cannot be added to a Marker as reference.");
  }
  // no point in adding the reference multiple times
  if (this.contains(reference)) {
    return;
  } else if (reference.contains(this)) { // avoid recursion
    // a potential reference should not hold its future "parent" as a reference
    return;
  } else {
    referenceList.add(reference);
  }
}
