maxOccurs=”unbounded” />
i want to generate this type of .xsd file using java code..? How can i do that.?
Specially how to generate Simple type elements and put restrictions on it ?
解决方案
Instead of creating your own simple type to represent integers starting with 0, you could leverage the existing xs:nonNegativeInteger type. I’ll demonstrate with an example.
SpThread
You can use the @XmlSchemaType annotation to specify what type should be generated in the XML schema for a field/property.
package forum;
import javax.xml.bind.annotation.XmlSchemaType;
public class SpThread {
private int durTime;
@XmlSchemaType(name=”nonNegativeInteger”)
public int getDurTime() {
return durTime;
}
public void setDurTime(int durTime) {
this.durTime = durTime;
}
}
Demo
You can use the generateSchema method on JAXBContext to generate an XML schema:
package forum;
import java.io.IOException;
import javax.xml.bind.*;
import javax.xml.transform.Result;
import javax.xml.transform.stream.StreamResult;
public class Demo {
public static void main(String[] args) throws Exception {
JAXBContext jc = JAXBContext.newInstance(SpThread.class);
jc.generateSchema(new SchemaOutputResolver() {
@Override
public Result createOutput(String namespaceUri, String suggestedFileName) throws IOException {
StreamResult result = new StreamResult(System.out);
result.setSystemId(suggestedFileName);
return result;
}
});
}
}
Output
Below is the XML schema that was generated.
