Jackson DataFormat XML's efficient application in Java
Jackson DataFormat XML is a library for serialization and derivativeized XML data for serialization and derivativeization of XML in Java.In the development of Java, the processing of XML data is very common, especially in the case of data exchange with external systems.Jackson DataFormat XML provides a simple and flexible way to process XML data, allowing developers to easily convert XML data into Java objects and convert the Java object to XML data.
To apply Jackson DataFormat XML efficiently in Java, some configuration and codes need to be performed.The following is a complete example. It demonstrates how to use the Jackson DataFormat XML library to sequence the Java object to XML data and sequence the XML data to the Java object.
First, you need to add Jackson DataFormat XML libraries to the project dependency item.You can use Maven or Gradle to manage the dependence of the project.
Maven dependencies:
<dependency>
<groupId>com.fasterxml.jackson.dataformat</groupId>
<artifactId>jackson-dataformat-xml</artifactId>
<version>2.12.1</version>
</dependency>
Gradle dependencies:
groovy
implementation 'com.fasterxml.jackson.dataformat:jackson-dataformat-xml:2.12.1'
Next, we can define a Java class to indicate data to indicate serialization and derivativeization.
import com.fasterxml.jackson.dataformat.xml.XmlMapper;
public class Person {
private String name;
private int age;
// Must be provided with a constructor without parameters
public Person() {
}
public Person(String name, int age) {
this.name = name;
this.age = age;
}
// getter and setter method
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
// The main method is used to demonstrate the process of serialization and device
public static void main(String[] args) throws Exception {
// Create an XMLMAPPER object
XmlMapper xmlMapper = new XmlMapper();
// Create a Person object
Person Person = New Person ("Zhang San", 25);
// Sequence the Person object to XML string
String xml = xmlMapper.writeValueAsString(person);
System.out.println(xml);
// Turn the XML string back -sequence to the Person object
Person deserializedPerson = xmlMapper.readValue(xml, Person.class);
System.out.println(deserializedPerson.getName());
System.out.println(deserializedPerson.getAge());
}
}
In the above code, we first created a XMLMAPPER object, which is used to perform serialization and derivativeization operations.Then, we created a Person object and serialized it to XML string.Next, we transformed the XML strings into the Person object and print out its attributes.
By running the above code, you will see the output result as follows:
<Person><name>张三</name><age>25</age></Person>
Zhang San
25
The above is a simple example of using the Jackson DataFormat XML library in Java to highly apply XML serialization and derivativeization in Java.Using this library, you can easily process XML data to achieve data exchange and storage with external systems.
