In this article, let us see how to avoid converting < to < ; and > to > ; and & to & ; during JAXB Marshalling operation.
1. CharacterEscapeHandler creation
Create a custom Escape Handler by implementing the CharacterEscapeHandler interface as given below.
public class JaxbCharacterEscapeHandler implements CharacterEscapeHandler {
public void escape(char[] buf, int start, int len, boolean isAttValue,
Writer out) throws IOException {
for (int i = start; i < start + len; i++) {
char ch = buf[i];
out.write(ch);
}
}
}
2. Marshaller Code
Use the below code snippet for JAXB Marshalling operation.
Note: Please go through the basics of using JAXB Marshalling code samples before using this example
import java.io.PrintWriter;
import java.io.StringWriter;
import java.io.Writer;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Marshaller;
import com.sun.xml.bind.marshaller.CharacterEscapeHandler;
import com.sun.xml.bind.marshaller.DataWriter;
public class JaxbMarshaller {
public static void main(String[] args) {
// Note: Provide input for the below objects
Object jaxbObject = null; // Create the right Input object
String packageName = jaxbObject.getClass().getPackage().getName(); // Provide the package name of the generated classes
try {
JAXBContext jaxbContext = JAXBContext.newInstance(packageName);
Marshaller marshaller = jaxbContext.createMarshaller();
// Set UTF-8 Encoding
marshaller.setProperty(Marshaller.JAXB_ENCODING, "UTF-8");
// The below code will take care of avoiding the conversion of < to < and > to > etc
StringWriter stringWriter = new StringWriter();
PrintWriter printWriter = new PrintWriter(stringWriter);
DataWriter dataWriter = new DataWriter(printWriter, "UTF-8", new JaxbCharacterEscapeHandler());
// Perform Marshalling operation
marshaller.marshal(jaxbObject, dataWriter);
System.out.println(stringWriter.toString());
} catch (JAXBException e) {
System.err.println("Error in marshalling...");
}
}
}
