我需要通过apache storm(部署在远程集群中)序列化复杂对象(opencv:Mat)。任何人都可以建议我一个很好的教程自定义kryo序列化或提出如何做到这一点的解决方案? 提前谢谢!
答案 0 :(得分:0)
我创建了一个bean
public class DataBean{
Mat imageMatrix;
int id;
public DataBean(){
}
public DataBean(int id, Mat matrix) {
setId(id);
setImageMatrix(matrix);
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public Mat getImageMatrix() {
return imageMatrix;
}
public void setImageMatrix(Mat matrix)
{
this.imageMatrix=matrix;
}
}
然后我创建了序列化程序如下:
public class DataBeankryo extends Serializer<DataBean> implements Serializable{
@Override
public DataBean read(Kryo arg0, Input arg1, Class<DataBean> arg2) {
DataBean bean=new DataBean();
bean.setId(arg1.readInt());
bean.setImageMatrix(arg0.readObject(arg1,org.opencv.core.Mat.class));
return bean;
}
@Override
public void write(Kryo arg0, Output output, DataBean bean) {
//arg0.register(org.opencv.core.Mat.class);
output.writeInt(bean.getId());
arg0.writeObject(output,bean.getImageMatrix(),arg0.getSerializer(org.opencv.core.Mat.class));
//arg0.writeClassAndObject(output, bean);
output.close(); }}
我希望这可以帮到你!
