Use the "JSON In Java" framework in the Java class library to achieve the serialization and derivativeization of JSON data

Use the "JSON In Java" framework in the Java class library to achieve the serialization and derivativeization of JSON data Summary: This article introduces how to use the "JSON in Java" framework in the Java library to achieve the serialization and derivativeization of JSON data.JSON (JavaScript Object Notation) is a lightweight data exchange format, which has become one of the data formats commonly used in modern web applications.The "JSON In Java" framework in Java provides a simple and convenient way to process JSON data. introduction: In modern web applications, data is usually transmitted in JSON format.JSON is a lightweight data exchange format that is easy to read and write, and it is also easy to analyze and generate.The "JSON In Java" framework in the Java class library provides various functions to process JSON data, including serialization and derivativeization. text: 1. Introduce JSON in Java framework Before the beginning, you need to introduce the "JSON In Java" framework.You can find the latest version of the framework in the central warehouse and add it to the dependence of the project.The following is an example of adding Maven dependence: <dependency> <groupId>org.json</groupId> <artifactId>json</artifactId> <version>20210307</version> </dependency> 2. Serialization of JSON data Serialization is the process of converting Java objects into JSON string.Using the "JSON in Java" framework, you can sequence the Java object into a JSON string through the following steps: // Import the required class import org.json.JSONObject; // Create a Java object Person Person = New Person ("Zhang San", 25); // Sequence java objects to JSON string String jsonString = new JSONObject(person).toString(); System.out.println(jsonString); In the above examples, the Java object called Person is first created, and the name and age attribute are set up.Then, the Java object is converted to the JSON object with the JSONObject class, and the Tostring () method is used to convert it to the JSON string.Finally, print the JSON string. 3. Reverse serialization of JSON data Capitalization is a process of converting the JSON string into a Java object.Using the "JSON in Java" framework, you can use the following steps to transform the JSON string back -sequencing into the Java object: // Import the required class import org.json.JSONObject; // Define a json string String jsonstring = "{\" name \ ": \" Zhang San \ ", \" Age \ ": 25}"; // Turn the JSON string back -sequencing into the Java object JSONObject jsonObject = new JSONObject(jsonString); String name = jsonObject.getString("name"); int age = jsonObject.getInt("age"); Person person = new Person(name, age); System.out.println(person); In the above examples, a JSON string containing names and age attributes is first defined.Then, use the JSONObject class to turn the JSON string back -sequence into JSON objects, and use GetString () and Getint () to obtain the corresponding attribute values.Finally, create a Java object based on the attribute value obtained and print it out. in conclusion: Through the "JSON in Java" framework, the serialization and derivativeization of JSON data can be easily realized.When processing the interface calls and data transmission of the web application, using this framework can make the processing of JSON data simpler and efficient. The above is the method of serializing and deepericularization of JSON data using the "JSON in Java" framework in the Java library.It is hoped that this article will help developers using the framework to process JSON data.
