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

JsonNode.findValues介绍

[英]Method for finding JSON Object fields with specified name, and returning found ones as a List. Note that sub-tree search ends if a field is found, so possible children of result nodes are not included. If no matching fields are found in this node or its descendants, returns an empty List.
[中]方法查找具有指定名称的JSON对象字段，并将找到的字段作为列表返回。请注意，如果找到字段，则子树搜索将结束，因此不包括结果节点的可能子节点。如果在此节点或其子节点中未找到匹配字段，则返回空列表。

代码示例
