JAXB Java編組錯誤

[英]JAXB Java Marshalling error

我試圖用JAXB封送一個簡單的Java類,但遇到了錯誤。 我正在尋找解決以下錯誤的建議,這些是錯誤:

javax.xml.bind.JAXBException
 - with linked exception:
[java.io.FileNotFoundException: C:\file.xml (Access is denied)]
    at javax.xml.bind.helpers.AbstractMarshallerImpl.marshal(Unknown Source)
    at JAXBExample.main(JAXBExample.java:23)
Caused by: java.io.FileNotFoundException: C:\file.xml (Access is denied)
    at java.io.FileOutputStream.open(Native Method)
    at java.io.FileOutputStream.<init>(Unknown Source)
    at java.io.FileOutputStream.<init>(Unknown Source)
    ... 2 more

當我嘗試為JAXB封送處理運行類時,將出現錯誤。 它是從教程網站( http://www.mkyong.com/java/jaxb-hello-world-example/ )下載的,因此應該是正確的。

這是元帥課:

import java.io.File;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Marshaller;

public class JAXBExample {
    public static void main(String[] args) {

      Customer customer = new Customer();
      customer.setId(100);
      customer.setName("mkyong");
      customer.setAge(29);

      try {

        File file = new File("C:\\file.xml");
        JAXBContext jaxbContext = JAXBContext.newInstance(Customer.class);
        Marshaller jaxbMarshaller = jaxbContext.createMarshaller();

        // output pretty printed
        jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);

        jaxbMarshaller.marshal(customer, file);
        jaxbMarshaller.marshal(customer, System.out);

          } catch (JAXBException e) {
        e.printStackTrace();
          }
    }
}

封送處理類引用Customer類。 這是客戶類別:

import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement
public class Customer {

    String name;
    int age;
    int id;

    public String getName() {
        return name;
    }

    @XmlElement
    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    @XmlElement
    public void setAge(int age) {
        this.age = age;
    }

    public int getId() {
        return id;
    }

    @XmlAttribute
    public void setId(int id) {
        this.id = id;
    }

}

該錯誤似乎與XML無關-您根本無權訪問您要打開的文件。

嘗試刪除“ C:\\\\”,以使該文件位於工作目錄中,而不是C驅動器的頂部。
