本文整理了Java中com.fasterxml.jackson.databind.JsonNode.findPath()方法的一些代码示例，展示了JsonNode.findPath()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。JsonNode.findPath()方法的具体详情如下：
包路径：com.fasterxml.jackson.databind.JsonNode
类名称：JsonNode
方法名：findPath

JsonNode.findPath介绍

[英]Method similar to #findValue, but that will return a "missing node" instead of null if no field is found. Missing node is a specific kind of node for which #isMissingNodereturns true; and all value access methods return empty or missing value.
[中]方法类似于#findValue，但如果未找到字段，则将返回“缺少节点”而不是null。缺失节点是#IsMissingNodeRe为真的特定类型的节点；所有值访问方法都返回空值或缺少值。

private Map<String, String> _getJsonHomeRootEndpointMap(JsonNode jsonNode) {
  Map<String, String> resourcesMap = new TreeMap<>();
  JsonNode resourcesJsonNode = jsonNode.findPath(
    JSONLDConstants.RESOURCES);
  Iterator<String> fieldNames = resourcesJsonNode.fieldNames();
  while (fieldNames.hasNext()) {
    String fieldName = fieldNames.next();
    JsonNode fieldValue = resourcesJsonNode.get(fieldName);
    if (fieldValue.has(JSONLDConstants.HREF)) {
      JsonNode hrefJsonNode = fieldValue.get(JSONLDConstants.HREF);
      resourcesMap.put(hrefJsonNode.asText(), fieldName);
    }
  }
  return resourcesMap;
}
