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

JsonNode.isContainerNode介绍

[英]Method that returns true for container nodes: Arrays and Objects.

Note: one and only one of methods #isValueNode, #isContainerNode and #isMissingNode ever returns true for any given node.
[中]方法，该方法为容器节点（数组和对象）返回true。
注意：对于任何给定节点，方法#isValueNode、#isContainerNode和#isMissingNode中只有一个会返回true。

代码示例

public static JsonNode searchJson(JsonNode tree, String searchKey)
  throws JsonProcessingException, IOException {
 if (tree == null) {
  return null;
 }
 if(tree.has(searchKey)) {
  return tree.get(searchKey);
 }
 if(tree.isContainerNode()) {
  for(JsonNode branch: tree) {
   JsonNode branchResult = searchJson(branch, searchKey);
   if (branchResult != null && !branchResult.isMissingNode()) {
    return branchResult;
   }
  }
 }
 return null;
}
