请勿使用setBounds(). Swing旨在与布局管理器一起使用.

Don't use setBounds(). Swing was designed to be used with layout managers.

您可以通过以下操作将文本字段添加到标签中:

You can add the text fields to the label by doing something like:

JLabel myLabel = new JLabel( new ImageIcon("system\\myBackground.jpg") );
mylabel.setLayout( new FlowLayout() );
mylabel.add(login);
mylabel.add(password);

为标签使用适当的布局管理器以获取所需的布局.

Use the appropriate layout manager for the label to get the desired layout.
