Java GLCanvas序列化

在我的应用程序中，我使用JOGL lib与OpenGL一起工作

我需要序列化javax.media.opengl.awt.GLCanvas的实现

import javax.media.opengl.*;
import javax.media.opengl.awt.GLCanvas;
import javax.media.opengl.glu.GLU;
import java.io.Serializable;

public class Canvas extends GLCanvas implements GLEventListener, Serializable {
private GLU glu;

private static final int FPS = 60;
private FPSAnimator animator;

public Canvas() {
    addGLEventListener(this);
}

@Override
public void init(GLAutoDrawable drawable) {
    drawable.setGL(new DebugGL2(drawable.getGL().getGL2()));

    glu = new GLU();

    animator = new FPSAnimator(this, FPS);
    animator.start();
}

@Override
public void display(GLAutoDrawable drawable) {
    if (!animator.isAnimating()) return;
    final GL2 gl = drawable.getGL().getGL2();

    gl.glClear(GL2.GL_COLOR_BUFFER_BIT | GL2.GL_DEPTH_BUFFER_BIT);

    setCamera(gl, glu, camera.getHeight(), camera.getOrigin());
}

@Override
public void reshape(GLAutoDrawable drawable, int x, int y, int width, int height) {
    final GL2 gl = drawable.getGL().getGL2();
    gl.glViewport(0, 0, width, height);
}

@Override
public void dispose(GLAutoDrawable drawable) {

}

private void setCamera(GL2 gl, GLU glu, float distance, Float origin) {
    gl.glMatrixMode(GL2.GL_PROJECTION);
    gl.glLoadIdentity();

    float widthHeightRatio = (float) getWidth() / (float) getHeight();
    glu.gluPerspective(45, widthHeightRatio, 1, 1000);
    glu.gluLookAt(origin.x, origin.y, distance, origin.x, origin.y, 0, 0, 1, 0);

    gl.glMatrixMode(GL2.GL_MODELVIEW);
    gl.glLoadIdentity();
}
}

我试着写我的画布

   fout = new FileOutputStream("F:\\canvas.ser");
   oos = new ObjectOutputStream(fout);
   oos.writeObject(mCanvas);

但我有一个错误：

因此，GLCanvas中的字段是不可序列化的。我能做什么？

不确定这是否能解决您的问题，但是

javax.media.opengl

建议您使用的是过时的jogl版本。您可以使用反射API在序列化期间将不可序列化字段设置为null，或者将GLCanvas包装到实现可外部化的自定义类中，并完全覆盖默认序列化，但这非常困难：s
