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.
