How to use the KONIG YAML framework in the Java library for data serialization and desertileization

How to use the KONIG YAML framework in the Java library for data serialization and desertileization I. Introduction In Java development, the serialization and dependency of data are common tasks.The KONIG YAML framework is a serialization and device -oriented JAVA library for handling Yaml (Yaml Ain'T Markup Language) format.This article will introduce how to use the KONIG YAML framework in Java for data serialization and derivativeization of data. Introduction to KONIG YAML framework The KONIG YAML framework is an open source Java class library, which aims to provide serialization and derivative support for YAML format data.YAML is a readable data format that is usually used to configure files and data exchange.The KONIG YAML framework can easily convert the Java object to the data in YAML format and convert YAML data back to the Java object. Third, the use of KONIG YAML The following will introduce how to use the KONIG YAML framework in the Java library for serialization and derivativeization of data. Step 1: Import Konig Yaml framework First, we need to import the related library of the Konig Yaml framework in the Java project.You can add the following dependencies in the construction file in Maven or Gradle projects: <dependency> <groupId>io.konig</groupId> <artifactId>konig-yaml</artifactId> <version>1.0.0</version> </dependency> Step 2: Define the Java object Next, we need to define a Java class to indicate data that is to be serialized and derived.For example, suppose we have a Person class that contains names and Age attributes: public class Person { private String name; private int age; // Eliminate the constructor, Getter, and Setter method } Step 3: Serialization to YAML data The serial sequence of Java objects to YAML data is very simple.We can use the YAMLWRITER class provided by Konig Yaml to complete: import io.konig.yaml.YamlWriter; import java.io.StringWriter; // Create Person objects Person Person = New Person ("Zhang San", 25); // Create StringWriter for receiving serialized YAML data StringWriter stringWriter = new StringWriter(); // Create yamlwriter objects YamlWriter writer = new YamlWriter(stringWriter); // Write the Person object into YAML data writer.write(person); // Close yamlwriter writer.close(); // Output YAML data System.out.println(stringWriter.toString()); Run the above code, and will output the following YAML data: name: "Zhang San" age: 25 Step 4: Capitalization to Java object It is also very simple to transform YAML data to the Java object.We can use the YamlReader class provided by Konig Yaml to complete: import io.konig.yaml.YamlReader; // Suppose we have a string containing yaml data String yamlstring = "name: \" Zhang San \ " age: 25"; // Create yamlreader objects YamlReader reader = new YamlReader(); // Create Person objects from YAML data Person person = reader.read(yamlString, Person.class); // Output the attribute value of the Person object System.out.println(person.getName()); System.out.println(person.getAge()); Run the above code, the result will be output: Zhang San 25 At this point, we have learned how to use the Konig YAML framework in the Java library for data serialization and derivativeization of data. in conclusion The KONIG YAML framework provides a simple way to serialize and derivativeize YAML data in Java.We can import the Konig Yaml library to define the Java object, use Yamlwriter for serialization, and use YamlReader for a back serialization to realize the mutual conversion between Java objects and YAML data.This method provides us with great convenience and flexibility for processing YAML format data. You can now use the tutorial provided by this article to start using the Konig Yaml framework in Java for the practice of data serialization and derivativeization.
