Question

我正在尝试将存储在我的MySQL中的图片作为类型Blob上传，并将其他信息（如名称，价格描述和ID）上传到TableView- From SceneBuilder。这是我的Getters and Setters课程：

package products;

import java.sql.Blob;
import javafx.beans.property.SimpleStringProperty;
import javafx.beans.property.StringProperty;


public class showp {
    public String id;
    public String name;
    public String price;
    public Blob picture;
    public String desc;
    public showp(String id, String name, String price,Blob image, String desc){
        this.id= id;
        this.name= name;
        this.price= price;
        this.picture=image;
        this.desc=desc;
    }
    //Getters
    public String getId(){
    return id;
    }
    public String getName(){
    return name;
    }
    public String getPrice(){
    return price;
    }
    public Blob getPicture(){
    return picture;
    }
    public String getDesc(){
    return desc;
    }
    //Setters
    public void setId(String Id){
    this.id=Id;
    }
    public void setName(String Name){
    this.name=Name;
    }
    public void setPrice(String Price){
    this.price=Price;
    }
    public void setPicture(Blob Picture){
    this.picture=Picture;
    }
    public void setDesc(String Desc){
    this.desc=Desc;
    }
}

这是一个类，我在其中用数据填充表：

 public void loadProducts() throws ClassNotFoundException{



      try {
            dc=new DbConncetion();
            Connection conn= dc.Connect();
            ol1=FXCollections.observableArrayList();
            ol1.clear();
            ResultSet rs = conn.createStatement().executeQuery("SELECT * FROM `products`");
            while(rs.next()){
                ol1.add(new showp(rs.getString(1),rs.getString(2),rs.getString(3), rs.getBlob(4) , rs.getString(5)));
            }
            pName.setCellValueFactory(new PropertyValueFactory<>("name"));
            priceP.setCellValueFactory(new PropertyValueFactory<>("price"));
                picP.setCellValueFactory(new PropertyValueFactory<>("image"));
            pView.setItems(null);
            pView.setItems(ol1);
        } catch (SQLException ex) {
            Logger.getLogger(Main1Controller.class.getName()).log(Level.SEVERE, null, ex);
        }


  }

我在这里和youtube上看到了很多例子，但我什么都不懂。任何人都可以解释我如何做到这一点。当我在我的表中执行该代码时，以这种格式com.mysql.jdbc.Blob@1b8f8da0显示名称，价格和Blob列。我只想要而不是com.mysql.jdbc.Blob@1b8f8da0来显示imageview中的真实图像或其他内容。提前致谢
