Consider this example -
I have a class called Report that has a field of type Message. The Message class has a field called "body" which is a string. "body" can be any string, but sometimes it contains properly formatted XML content. How can I ensure that when the "body" contains XML content, the serialization takes the form of an XML structure rather than what it gives at present?
Here is the code with the output -
Report class
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlType;
@XmlRootElement(name = "Report")
@XmlType(propOrder = { "message"})
public class Report
{
private Message message;
public Message getMessage() { return message; }
public void setMessage(Message m) { message = m; }
}
Message class
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlType;
@XmlType(propOrder = { "body" })
public class Message
{
private String body;
public String getBody() { return body; }
@XmlElement
public void setBody(String body) { this.body = body; }
}
Main
import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Marshaller;
public class SerializationTest
{
public static void main(String args[]) throws Exception
{
JAXBContext jaxbContext = JAXBContext.newInstance(Report.class);
Marshaller jaxbMarshaller = jaxbContext.createMarshaller();
jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
Report report = new Report();
Message message = new Message();
message.setBody("Sample report message.");
report.setMessage(message);
jaxbMarshaller.marshal(report, System.out);
message.setBody("<rootTag><body>All systems online.</body></rootTag>");
report.setMessage(message);
jaxbMarshaller.marshal(report, System.out);
}
}
The output is as follows -
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Report>
<message>
<body>Sample report message.</body>
</message>
</Report>
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Report>
<message>
<body><rootTag><body>All systems online.</body></rootTag></body>
</message>
</Report>
As you can see in the above output, for the second instance of "body", the serialization produced
<body><rootTag><body>All systems online.</body></rootTag></body>
instead of
<body><rootTag><body>All systems online.</body></rootTag></body>
How to solve this problem?
