JSONITER Scala Core: JSON processing toolbox in the Java class library

JSONITER Scala Core: JSON processing toolbox in the Java class library Introduction: JSONITER Scala Core is a Java class library for handling JSON.It provides a fast and efficient JSON serialization and deepening function, enabling developers to easily process JSON data in Java applications.This article will introduce the basic concepts and usage methods of JSONiter Scala Core, and provide corresponding programming examples and related configuration descriptions. JSON processing is very common in modern software development, especially when constructing and maintaining Web services and APIs.JSON is a lightweight data exchange format that is commonly used in data transmission and storage.To process JSON data with Java, you need to write a large amount of code and complex analysis logic.The Jsoniter Scala Core library provides developers with a simple and efficient solution. Installation and configuration: Before using JSONITER Scala Core, we need to add corresponding dependencies to the configuration file of the project.You can introduce the following code to Maven or Gradle configuration files to introduce JSONITER Scala Core libraries: Maven configuration: <dependency> <groupId>com.github.plokhotnyuk.jsoniter-scala</groupId> <artifactId>jsoniter-scala-core_2.13</artifactId> <version>2.7.1</version> </dependency> Gradle configuration: groovy implementation 'com.github.plokhotnyuk.jsoniter-scala:jsoniter-scala-core_2.13:2.7.1' Example: Below we will introduce how to use JSONITER Scala Core for serialization and derivativeization of JSON. 1. The serialization object is JSON string: First of all, we need to define a Java class to indicate the object of serialization.For example, consider the following Person classes: scala case class Person(name: String, age: Int) Next, we can use the JSONITER Scala Core to sequence the Person object to the JSON string.The following is an example code: scala import com.github.plokhotnyuk.jsoniter_scala.core._ val person = Person("Alice", 25) val jsonString = writeToString(person) println(jsonString) In the above code, we first created a Person object, and then serialized it into a JSON string with the method of `` `)` `` `` `` ``).Finally, we print the JSON string after serialized. 2. Turn the JSON string back -sequentially serialized into the object: Contrary to serialization, we can use the JSONITER Scala Core to turn the JSON string to the object.The following is an example code: scala val jsonStr = """{"name":"Alice","age":25}""" val person = readFromString[Person](jsonStr) println(person) In the above code, we first provide a JSON string, and then use the `ReadFromString () method to series into the Person object.Finally, we print the PERSON object after the output reverse sequentialization. Summarize: This article introduces the basic concepts and usage methods of the JSONiter Scala Core library.The library provides a fast and efficient way to process JSON data.We understand how to convert Java objects into JSON string and convert the JSON string into Java objects through serialization and derivativeization methods.By learning these basic concepts, developers can easily process JSON data in Java applications.I sincerely hope that this article will help you.
