XSTREAM framework introduction and use tutorial
XSTREAM is a Java object serialization and desertileization library. It can convert the object to XML or JSON format, and it can reverse the process. The XML or JSON will be converted back to the object.XSTREAM provides developers with a convenient and simple way to handle the serialization and derivatives of complex objects without manually writing tedious codes.
The main features of XSTREAM are flexibility and scalability.Developers can use annotations or configuration files to define the process of serialization and derivativeization to meet various needs.In addition, XSTREAM also provides a set of simple and easy -to -use APIs, enabling developers to quickly get started and start using the framework.
The steps of using the XSTREAM framework are as follows:
Step 1: Import the dependency library of the XSTREAM framework.You can introduce the following Maven dependencies to the construction document of the project:
<dependency>
<groupId>com.thoughtworks.xstream</groupId>
<artifactId>xstream</artifactId>
<version>1.4.15</version>
</dependency>
Step 2: Create a Java object and annotate the fields that need to be serialized and deeper.For example, we create a class called Person:
public class Person {
@XStreamAlias("name")
private String name;
@XStreamAlias("age")
private int age;
public Person(String name, int age) {
this.name = name;
this.age = age;
}
// omit the getter and setter method
}
In the above code, we use the `@xstreamalias` annotation provided by XSTREAM to specify the element name in the xml.
Step 3: Use XSTREAM for serialization and dependentization operation.Here are some common operation examples:
The sequence of the object to XML string:
XStream xstream = new XStream();
String xml = xstream.toXML(person);
System.out.println(xml);
Calculate the XML string to the object:
XStream xstream = new XStream();
Person person = (Person) xstream.fromXML(xml);
System.out.println(person.getName());
System.out.println(person.getAge());
The sequence of the object to the JSON string:
XStream xstream = new XStream(new JsonHierarchicalStreamDriver());
String json = xstream.toXML(person);
System.out.println(json);
Circularize the JSON string to the object:
XStream xstream = new XStream(new JsonHierarchicalStreamDriver());
Person person = (Person) xstream.fromXML(json);
System.out.println(person.getName());
System.out.println(person.getAge());
The XSTREAM framework also supports many other functions, such as field aliases, custom converters, ignoring fields, etc.You can learn more about the official documentation of XSTREAM.
To sum up, the XSTREAM framework is a convenient and easy -to -use Java object serialization and deepening library.By using XSTREAM, developers can easily convert the object to XML or JSON format, and can easily convert XML or JSON back to objects.If you need to handle the serialization and derivativeization of complex objects, and do not want to write tedious code, xstream is a good choice.
