本文整理了Java中org.jclouds.json.Json.fromJson()方法的一些代码示例，展示了Json.fromJson()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。Json.fromJson()方法的具体详情如下：
包路径：org.jclouds.json.Json
类名称：Json
方法名：fromJson

Json.fromJson介绍

[英]Deserialize the object from json. If the object is a generic type, use #fromJson(Object,Type)
[中]从json反序列化对象。如果对象是泛型类型，请使用#fromJson（对象，类型）

代码示例

代码示例来源：origin: stackoverflow.com

Json json = new Json();
json.setTypeName(null);
json.setUsePrototypes(false);
json.setIgnoreUnknownFields(true);
json.setOutputType(OutputType.json);

// I'm using your file as a String here, but you can supply the file as well
Data data = json.fromJson(Data.class, "{\"table\": [{\"id\": 1},{\"id\": 2},{\"id\": 3},{\"id\": 4}]}");
