How to serialize a Java object to an XML string
Java objects can be serialized into XML strings using JAXB. First introduce JAXB dependencies into the project, especially Java 9 and above. Then add the @XmlRootElement annotation to the class, and provide getter/setter and @XmlElement annotations for the field. Then create a Marshaller through JAXBContext and combine it with StringWriter to convert the object into a formatted XML string. Ensure that the class has a no-argument constructor and uses annotations correctly, and finally outputs XML content such as Alice30.
