JsonPath/Jackson: how to deserialize JSON array to a single Object (“[1,2,3]” -> Vector3d instance)?

问题 Abstract I'm using JsonPath to select parts of a JSON file and deserialize it into POJOs. This works fine for Strings, but I can't figure out how to get Jackson to deserialize a three-element array as a single instance of my own class (Vector3d).

1. json的概念： JSON(JavaScript Object Notation) 是一种轻量级的数据交换格式，它使得人们很容易的进行阅读和编写。同时也方便了机器进行解析和生成。适用于进行数据交互的场景，比如网站前台与后台之间的数据交互。 2.json中常用的模块： json.dumps 实现python类型转化为json字符串 json.loads 实现json字符串转化为python的数据类型 json.dump 实现把python类型写入类文件对象 json.load 实现类文件对象中的json字符串转化为python类型 代码示例： import json mydict = { "store": { "book": [ {"category": "reference", "author": "Nigel Rees", "title": "Sayings of the Century", "price": 8.95 }, {"category": "fiction", "author": "Evelyn Waugh", "title": "Sword of Honour", "price": 12.99 }, ], } } # indent实现换行和空格 # ensure_ascii=False实现让中文写入的时候保持为中文 json_str = json.dumps

问题 We are using a tool which uses jayway library for evaluating JSONpath expression. Javascript does NOT seem to work with it . How can I use regular expression in the JSONPath in such a case. For instance, in the below example I would like to filter all book titles whose title has the word "Sword" in it: { "store": { "book": [ { "category": "reference", "author": "Nigel Rees", "title": "Sayings of the Century", "price": 8.95 }, { "category": "fiction", "author": "Evelyn Waugh", "title": "Sword
