Jackson DataFormat: AVRO framework introduction and use in Java

Jackson DataFormat: Avro is a module of the Jackson library. It allows Java developers to use AVRO format for serialization and dependent operation.AVRO is a high -performance, scalable data serialization system, which provides a compact binary format and contains a JSON representation for describing the data mode. Below is a sample code that uses Jackson DataFormat: AVRO framework for AVRO serialization and derivativeization: First of all, we need to add Jackson DataFormat: Avro's dependencies to pom.xml: <dependency> <groupId>com.fasterxml.jackson.dataformat</groupId> <artifactId>jackson-dataformat-avro</artifactId> <version>2.10.2</version> </dependency> Next, we can define a Java class to indicate the data that we want to serialize and deeperate: public class Person { private String name; private int age; // omit the getter and setter method } Then, we can use Jackson DataFormat: Avro for serialization and back -sequencing operations: import com.fasterxml.jackson.dataformat.avro.AvroMapper; import com.fasterxml.jackson.dataformat.avro.AvroSchema; public class AvroExample { public static void main(String[] args) throws IOException { // Create AVROMAPPER objects AvroMapper avroMapper = new AvroMapper(); // Create Person objects Person person = new Person(); person.setName("John"); person.setAge(30); // The sequence of the Person object is transformed into a byte array in the AVRO format byte[] serializedPerson = avroMapper.writer() .with(new AvroSchema(Person.class)) .writeValueAsBytes(person); // Sequence the adverse sequence of the byte array in the AVRO format into a Person object Person deserializedPerson = avroMapper.reader(Person.class) .with(new AvroSchema(Person.class)) .readValue(serializedPerson); // Person objects after the output back -sequentialization System.out.println(deserializedPerson); } } The above code demonstrates how to use Jackson DataFormat: AVRO for serialization and dependentization operation.First of all, we create an Avromapper object, then create a Person object and serialize it into an array in Avro format.Finally, we transformed the byte array to the Person object and output the result of the back -sequentialization. Summarize: This article introduces the use of Jackson DataFormat: Avro framework.By adding Jackson DataFormat: Avro's dependence, we can use the AVRO format for data serialization and derivativeization of data.The above example demonstrates how to use the Jackson DataFormat: Avro for serialization and back -sequence operation, and provide a simple Java class to represent the data to be operated.I hope this article can help you learn and use Jackson DataFormat: Avro.
