How Java uses XStream serialization and deserialization

XStream is a serialization and deserialization framework between Java objects and XML, which can convert Java objects into XML format and also convert XML formatted data back into Java objects. The design goal of XStream is to simplify the conversion between Java objects and XML data, providing a simple API interface that eliminates the need for developers to pay attention to the details of XML data structures. The following is an introduction to the key methods commonly used in XStream and sample code: 1. Initialize XStream object Firstly, we need to create an XStream object and perform some basic configuration. XStream xstream = new XStream(); 2. Serialize Java objects into XML The toXML () method can be used to convert Java objects into XML formatted strings. Person person = new Person("John", 25); String xml = xstream.toXML(person); System.out.println(xml); 3. Deserialize XML into Java objects The from XML () method can be used to convert XML formatted strings into Java objects. String xml = "<person><name>John</name><age>25</age></person>"; Person person = (Person) xstream.fromXML(xml); System.out.println(person.getName()); System.out.println(person.getAge()); 4. Custom XML tag name If you need to use a custom XML tag name, you can use the alias() method to map the Java class name to the XML tag name. xstream.alias("person", Person.class); 5. Ignore a field If you do not want to include a field in XML, you can use the omitField() method to ignore it. xstream.omitField(Person.class, "age"); 6. Add additional XML tags In addition to the fields of Java objects, we can also manually add some additional XML tags. xstream.aliasField("full-name", Person.class, "name"); Maven Dependency: <dependency> <groupId>com.thoughtworks.xstream</groupId> <artifactId>xstream</artifactId> <version>1.4.17</version> </dependency> Through the above introduction, you can use the XStream framework for serialization and deserialization operations between Java objects and XML.
