public class MyPluginAction {
    public void actionPerformed(AnActionEvent e) {
        // 获取当前上下文
        DataContext dataContext = e.getDataContext();
        
        // 获取编辑器对象
        Editor editor = PlatformDataKeys.EDITOR.getData(dataContext);
        
        // 获取当前打开文件的VirtualFile对象
        VirtualFile file = FileEditorManager.getInstance(e.getProject()).getFile(editor.getDocument());
        
        // 获取文件路径
        String filePath = file.getPath();
        
        // 打印文件路径
        System.out.println("当前打开文件的路径：" + filePath);
    }
