In fact, the Object here is equivalent to the Map For example, an Address object contains the following Key-Value: City: BeijingStreet: Chaoyang RoadPostcode: 100025 (integer) JSON format: {"city":"Beijing","street":" Chaoyang Road ","postcode":100025} Value can also be another Object or array. Therefore, a complex Object can be nested. For example, a Person Object contains the name and address o

What is JSONJSON is an abbreviation for JavaScript object Notation (JavaScript objects notation), which is a lightweight data format and is based on a subset of JavaScript. As with XML, JSON is also a syntax for storing and exchanging textual information. JSON is smaller, faster, and easier to parse than XML. . These features make JSON an ideal data exchange la

JSON Brief Introduction JSON (The full name is JavaScript objectnotation) is a lightweight data interchange format. It is based on a subset of JavaScript syntax standards. JSON is a completely language-independent text format that can be easily transmitted across networks, platforms, and programs. JSON's syntax is simple, easy to read and write, and also easy to

relatively easy to check that the data being sent to the client is well-formed and valid. You can also use the data schema to verify the correctness and validity of the XML. Using JSON, this task is manual and involves verifying that the response object contains the correct attributes.In the client, it is difficult to find errors from both. In the case of XML, the browser is completely unable to format the

sharing. A. XML files are large, complex file formats, and bandwidth occupied by transmission;B. Both the server side and the client side require a large amount of code to parse XML, resulting in abnormal and complex server and client code and difficulty in maintenance;C. The XML parsing methods for different browsers on the client are inconsistent, and a lot of code needs to be repeated;D. It takes a lot of resources and time for the server and client to parse XML.

Moreover, it detects that the Employee. Department attribute produces a loop, so it replaces this value with an object reference {"$ ref": "1. Object references are non-standard

); (2) String toJson (Object src ); (3) String toJson (Object src, Type typeOfSrc ); Method (1) is used to convert a JsonElement Object (such as JsonObject and JsonArray) to JSON data. Method (2) is used to serialize a specified Object to JSON data; method (3) is used to serialize the specified Object (including the generic type) to the corresponding JSON data.
