Analysis of the simple YAML framework technical principles and advantages of the simple YAML framework in the java class library
I. Overview
Yaml (belongs to "Yaml Ain'T Markup Language") is a human -friendly data serialized language that is used to store and exchange data in a highly readable and easy -to -understand manner.In Java development, YAML has become a common configuration file format for the necessary data for storing and configuration applications.In order to easily handle the YAML file, the Java class library provides some simple YAML framework technology to help developers read, operate and write Yaml file easily.This article will analyze the principles and advantages of these YAML framework technology.
Second, the simple YAML framework technology in the Java class library
1. SnakeYAML
Snakeyaml is a powerful Java library for serialization and derivativeization between Java objects and YAML data.It analyzes the YAML file as a Java object and provides flexible APIs for the data of the operation and modification of the object.The following is a sample code that uses Snakeyaml to analyze the yaml file and convert it to the Java object:
import org.yaml.snakeyaml.Yaml;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.util.Map;
public class SnakeYamlExample {
public static void main(String[] args) {
try {
Yaml yaml = new Yaml();
FileInputStream inputStream = new FileInputStream("config.yml");
Map<String, Object> data = yaml.load(inputStream);
System.out.println(data);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
}
2. Jackson YAML
Jackson is a popular Java library for serialization and derivativeization between Java objects and JSON data.The Jackson library also provides support for YAML, which can be used to read and write Yaml files.The following is a sample code that uses Jackson Yaml to read Yaml files and converts it into the Java object:
import com.fasterxml.jackson.databind.ObjectMapper;
import java.io.File;
import java.io.IOException;
import java.util.Map;
public class JacksonYamlExample {
public static void main(String[] args) {
try {
ObjectMapper mapper = new ObjectMapper(new YAMLFactory());
Map<String, Object> data = mapper.readValue(new File("config.yml"), Map.class);
System.out.println(data);
} catch (IOException e) {
e.printStackTrace();
}
}
}
Third, the advantages of simple YAML framework technology
1. High readability: YAML uses indentation and symbols to indicate the hierarchical structure, making the reading and editing of the configuration file more intuitive and easy to understand.
2. Flexibility: Use the YAML framework technology to easily read and operate data in the YAML file, and map it to the Java object, so that flexible data operations and processing can be performed in the code.
3. Maintenance of the data structure: YAML framework technology can maintain the data structure integrity in the YAML file to ensure that the data will not be lost or changed during serialization and derivativeization.
4. Scalability: By using the YAML framework technology, developers can easily expand and customize the data structure of YAML files to meet specific application needs.
Summary: The simple YAML framework technology in the Java class library provides developers with a convenient, highly readable and flexible way to process YAML files.Whether you choose Snakeyaml or Jackson Yaml, you can easily read, operate and write Yaml files with your own API.These simple YAML framework technology provides rapid analysis and processing capabilities for YAML files, providing developers with a better development experience and flexibility.
