我知道这将是一个重复的问题，但我无法在我的案例中找到答案。我在MySQL数据库中有一个URL的图片（比如这个https://i.imgur.com/VcV0SG.jpg）。所以我需要在JTable中渲染这些图像。我怎样才能做到这一点？有谁能够帮我？提前谢谢。
代码
java.lang.reflect.Type listType = new TypeToken<ArrayList<Products>>() {}.getType();
List<Products> productsList = new Gson().fromJson(json, listType);
for(Products pro : productsList)
{
DefaultTableModel model = (DefaultTableModel) productsTable.getModel();
Vector<String> row = new Vector<String>();
row.add(pro.getCode());
row.add(pro.getName());
row.add(pro.getPrice());
//returns String (url of the image like `https://i.imgur.com/VcV0SG.jpg`)
row.add(pro.getPic());
model.addRow(row);
}

我知道你知道如何从MySQL中提取数据。如果您已有数据，则剩下的部分非常简单。使用import javax.swing.*;
import javax.swing.table.DefaultTableModel;
import java.awt.*;
import java.net.MalformedURLException;
import java.net.URL;
public class Main extends JPanel {
public static void main(String[] args) {
EventQueue.invokeLater(() -> {
try {
showGui();
} catch (MalformedURLException e) {
e.printStackTrace();
}
});
}
public Main() throws MalformedURLException {
Icon icon1 = new ImageIcon(new URL(
"https://www.cleverpetproducts.com/wp-content/uploads/2018/03/tardar.jpg"));
Icon icon2 = new ImageIcon(new URL(
"https://www.cleverpetproducts.com/wp-content/uploads/2018/03/tardar.jpg"));
Icon icon3 = new ImageIcon(new URL(
"https://www.cleverpetproducts.com/wp-content/uploads/2018/03/tardar.jpg"));
String[] columnNames = {"Picture", "Text"};
Object[][] data = {
{icon1, "Text 1"},
{icon2, "Text 2"},
{icon3, "Text 3"},
};
DefaultTableModel model = new DefaultTableModel(data, columnNames) {
public Class getColumnClass(int column) {
return getValueAt(0, column).getClass();
}
};
JTable table = new JTable(model);
table.setPreferredSize(new Dimension(500, 500));
table.getColumn(columnNames[0]).setPreferredWidth(300);
table.getColumn(columnNames[1]).setPreferredWidth(100);
table.setRowHeight(0, 100);
table.setRowHeight(1, 100);
table.setRowHeight(2, 100);
JScrollPane scrollPane = new JScrollPane(table);
add(scrollPane);
}
private static void showGui() throws MalformedURLException {
JFrame frame = new JFrame("Icon showcase");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(new Main());
frame.setLocationByPlatform(true);
frame.pack();
frame.setVisible(true);
}
}
。这是一个例子：
