Java HTML/XML - 如何使用JAXB使用xml模式检查java值

import java.io.File;

import javax.xml.XMLConstants;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.util.JAXBSource;
import javax.xml.validation.Schema;
import javax.xml.validation.SchemaFactory;

public class Main {

  public static void main(String[] args) throws Exception {
    SchemaFactory sf = SchemaFactory
        .newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
    Schema schema = sf.newSchema(new File("customer.xsd"));

    JAXBContext jc = JAXBContext.newInstance(Customer.class);

    Customer customer = new Customer();
    // populate the customer object
    JAXBSource source = new JAXBSource(jc, customer);
    schema.newValidator().validate(source);
  }

}

class Customer{}
