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

JsonNode.path介绍

[英]This method is similar to #get(int), except that instead of returning null if no such element exists (due to index being out of range, or this node not being an array), a "missing node" (node that returns true for #isMissingNode) will be returned. This allows for convenient and safe chained access via path calls.
[中]此方法与#get（int）类似，只是如果不存在此类元素（由于索引超出范围，或者此节点不是数组），则不会返回null，而是返回“缺少的节点”（为#isMissingNode返回true的节点）。这允许通过路径调用进行方便和安全的链接访问。
