Jackson DataFormat: The use guide of the Smile framework in the Java library

Jackson DataFormat: The use guide of the Smile framework in the Java library Smile (Simple Binary Encoding for XML) is a framework for serialization and dependentization of high -efficiency data in the Java library.It uses a binary format to encode data, which can provide smaller data transmission size and faster serialization.This article will introduce you how to use Jackson DataFormat: Smile framework in the Java library and provide some Java code examples. 1. Introduce the Smile library First, you need to introduce Smile libraries in your Java project.You can use Maven or Gradle to manage dependency relationships.In your project configuration file, add the following dependencies: <dependency> <groupId>com.fasterxml.jackson.dataformat</groupId> <artifactId>jackson-dataformat-smile</artifactId> <version>2.13.0</version> </dependency> 2. Turn the object sequence to SMILE format Next, let's see a example of serializing the Java object to Smile format.Suppose we have a class called `Person`, with the attributes of` name` and `age`: public class Person { private String name; private int age; public Person() {} public Person(String name, int age) { this.name = name; this.age = age; } // Getters and setters } Below is a code example that sequences the `Person` to the Smile format: ObjectMapper mapper = new ObjectMapper(new SmileFactory()); Person Person = New Person ("Zhang San", 25); byte[] smileData = mapper.writeValueAsBytes(person); In the above example, we created an example of the `ObjectMapper` and used the` SmileFactory` as its factory.Then, we convert the `Person` object to the byte array of Smile format. 3. Circular sequencing Smile data into objects Let's see a example of serializing Smile data into Java objects.Using the byte array generated in the example of the `Person` class and serialized examples, we can perform the following operations: Person deserializedPerson = mapper.readValue(smileData, Person.class); System.out.println("Name: " + deserializedPerson.getName()); System.out.println("Age: " + deserializedPerson.getAge()); In the above code, we use the `Readvalue` method to convert Smile data back to the` Person` object, and print the `name` and` aggestal attributes of the objectized objectized objects. In summary, you now understand how to use Jackson DataFormat: Smile framework for data serialization and derivativeization in the Java library.By using SMILE format, you can get smaller data size and faster speed when transmitting and storing data.Hope this article will help you! Please note that in order to run the above code example, you need to import the following packages: import com.fasterxml.jackson.databind.ObjectMapper; import com.fasterxml.jackson.dataformat.smile.SmileFactory; I hope these example code can help you start using Jackson DataFormat: Smile framework.I wish you a happy programming!
