java swing 文件拖拽解析

好的，关于Java Swing文件拖拽解析，您可以参考以下代码实现：

import javax.swing.*;
import java.awt.*;
import java.awt.datatransfer.*;
import java.awt.dnd.*;
import java.io.*;

public class FileDrop extends JPanel implements DropTargetListener {

    private DropTarget dropTarget;
    private JLabel message;

    public FileDrop() {
        setLayout(new BorderLayout());
        message = new JLabel("拖拽文件到此区域");
        message.setHorizontalAlignment(SwingConstants.CENTER);
        add(message, BorderLayout.CENTER);
        dropTarget = new DropTarget(this, DnDConstants.ACTION_COPY_OR_MOVE, this, true);
    }

    @Override
    public void dragEnter(DropTargetDragEvent dtde) {}

    @Override
    public void dragOver(DropTargetDragEvent dtde) {}

    @Override
    public void dropActionChanged(DropTargetDragEvent dtde) {}

    @Override
    public void dragExit(DropTargetEvent dte) {}

    @Override
    public void drop(DropTargetDropEvent dtde) {
        try {
            dtde.acceptDrop(DnDConstants.ACTION_COPY_OR_MOVE);
            Transferable transferable = dtde.getTransferable();
            DataFlavor[] flavors = transferable.getTransferDataFlavors();
            for (DataFlavor flavor : flavors) {
                if (flavor.isFlavorJavaFileListType()) {
                    Object data = transferable.getTransferData(flavor);
                    if (data instanceof java.util.List) {
                        java.util.List<File> files = (java.util.List<File>) data;
                        for (File file : files) {
                            System.out.println("文件路径：" + file.getAbsolutePath());
                        }
                    }
                }
            }
            dtde.dropComplete(true);
        } catch (Exception e) {
            e.printStackTrace();
            dtde.dropComplete(false);
        }
    }

    public static void main(String[] args) {
        JFrame frame = new JFrame("文件拖拽解析");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(400, 300);
        frame.setLocationRelativeTo(null);
        frame.setContentPane(new FileDrop());
        frame.setVisible(true);
    }
}

这是一个基于Java Swing实现的文件拖拽解析程序，您可以将文件拖拽到窗口中间的区域，程序会将文件路径输出到控制台中。希望对您有所帮助。
