Java GSON: Getting the list of all keys under a JSONObject

阅读更多关于 Java GSON: Getting the list of all keys under a JSONObject

I have got GSON as a JSON parser in Java, but the keys aren't always the same. For example. I have the following JSON: { "The Object I already know": { "key1":"value1", "key2":"value2", "AnotherObject": { "anotherKey1":"anotherValue1", "anotherKey2":"anotherValue2" } } I have already got the JSONObject "The Object I already know". Now I need to get all of the JSONElements for this Object, this would be "Key1", "Key2" and "AnotherObject". Thanks in advance. EDIT: The Output should be a String Array with all the keys for the JSONObject You can use JsonParser to convert your Json into an

问题 I'm building a RESTful web service. I've been locked in a situation where I'm not able to proceed. I've a DAO (a POJO) that has a JSONObject as a member variable. When I try to make a POST call from client (Postman or user-defined javascript) and try to debug, the value gathered in the getter of the JSONObject is empty ({}) whereas the other members of the class obtain their appropriate values. I've tried annotating the JSONObject and its getter with @XmlElement , @JsonProperty and so on..

1. 导入依赖这里以 20180813 的 json 版本为例 <dependency> <groupId>org.json</groupId> <artifactId>json</artifactId> <version>20180813</version> </dependency> 2. 构建 json 2.1 直接构建 JSONObject obj = new JSONObject(); obj.put(key, value); 直接构建即直接实例化一个 JSONObject 对象，而后调用其 put() 方法，将数据写入。put() 方法的第一个参数为 key 值，必须为 String 类型，第二个参数为 value，可以为 boolean、double、int、long、Object、Map 以及 Collection 等。当然，double 以及 int 等类型只是在 Java 中，写入到 json 中时，统一都会以 Number 类型存储。 2.2 使用HashMap构建使用 HashMap 构建 json，实际上即先创建好一个 HashMap 对象并且将数据打包进去，而后在创建 JSONObject 时将其作为一个参数传进去。 Map<String, Object> data = new HashMap<String, Object>(); data.put(

Serialize multiple forms together?

阅读更多关于 Serialize multiple forms together?

Can you serialize multiple forms into one so that only one post or ajax request is made? I have searched around and it is all for submiting each form separently via post/ajax. When you use the jQuery serialize() function, it simply turns your form into a string in the format a=1&b=2&c=3 . So you can certainly apply this function to two forms and concatenate the result, with an & between them, and use the result in your ajax call. You'd want some checks to make sure neither string is empty when you do the concatenation. If you run $('form').serialize() on a page with multiple forms, it will

java FastJson的使用总结

阅读更多关于 java FastJson的使用总结

1.前言 1.1.FastJson的介绍: 　　JSON (javaScript Object Notation)是一种轻量级的数据交换格式。主要采用键值对( {"name": "json"} )的方式来保存和表示数据。 JSON 是 JS 对象的字符串表示法，它使用文本表示一个 JS 对象的信息，本质上是一个字符串。　　JSON的处理器有很多,这里我介绍一下FastJson,FastJson是阿里的开源JSON解析库,可以解析JSON格式的字符串，支持将Java Bean序列化为JSON字符串，也可以从JSON字符串反序列化到JavaBean。是一个极其优秀的Json框架,Github地址: FastJson 1.2.FastJson的特点: 1.FastJson数度快,无论序列化和反序列化,都是当之无愧的fast 2.功能强大(支持普通JDK类包括任意Java Bean Class、Collection、Map、Date或enum) 3.零依赖(没有依赖其它任何类库) 1.3.FastJson的简单说明: FastJson对于json格式字符串的解析主要用到了下面三个类： 1.JSON：fastJson的解析器，用于JSON格式字符串与JSON对象及javaBean之间的转换 2.JSONObject：fastJson提供的json对象 3.JSONArray
