Question

我试图用jaxb编组一个包含Image的对象，然后解组它（即保存/加载）。

有没有办法存储该图片？

我正在尝试创建一个返回描述swt.image imagedata的字节数组的函数，但是一旦我将其标记为@XmlElement，存储它的过程就会失败抛出这样的异常：

com.sun.xml.internal.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions
JAXB annotation is placed on a method that is not a JAXB property
    this problem is related to the following location:
        at @javax.xml.bind.annotation.XmlElement()

另外，我已经测试过将SWT.Image转换为AWT.BufferedImage，但我仍然得到相同的异常。

您的异常表示您已在不是访问者的方法（get / set方法）上放置了注释。以下是使用java.awt.Image属性的示例：

<强>根

package forum9094655;

import java.awt.Image;

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement
public class Root {

    private Image image;

    public Image getImage() {
        return image;
    }

    public void setImage(Image image) {
        this.image = image;
    }

}

package forum9094655;

import java.awt.Image;
import java.awt.image.BufferedImage;

import javax.xml.bind.JAXBContext;
import javax.xml.bind.Marshaller;

public class Demo {

    public static void main(String[] args) throws Exception {
        JAXBContext jc = JAXBContext.newInstance(Root.class);

        Root root = new Root();
        Image image = new BufferedImage(1,1,BufferedImage.TYPE_INT_RGB);
        root.setImage(image);

        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(root, System.out);
    }

}

JAXB编组/解组SWT.Image或AWT BufferedImage
