The like this: is not very clear, but you can add spacing by adding a transparent border of a certain width to the label
像这样：不是很清楚，但是可以通过给label添加一定宽度的透明边框来增加间距

If you're trying to push the label to one side of it's container, you can add a glue. Something like this:
如果您试图将标签推到容器的一侧，您可以添加胶水。像这样的东西：
JPanel panel = new JPanel();
panel.setLayoutManager(new BoxLayout(panel, BoxLayout.LINE_AXIS);
panel.add(new JLabel("this is your label with it's image and text"));
panel.add(Box.createHorizontalGlue());
Though your question isn't very clear.
虽然你的问题不是很清楚。

You dont need to modify the preferredSize of the JLabel, you can use the GridBagLayoutManager to specify separations between components, you only have to use the GridBagLayout in the container and add the JXLabel to it with a GridBagConstraintsobject specifiying the insets to the left:
您不需要修改 JLabel 的 preferredSize，您可以使用GridBagLayoutManager 来指定组件之间的分隔，您只需要在容器中使用 GridBagLayout 并使用GridBagConstraints对象向其添加 JXLabel 并指定左侧的插图：
JPanel panel=new JPanel(new GridBagLayout());
JLabel label=new JLabel("xxxxx");
GridBagConstraints constraints=new GridBagConstraints();
constraints.insest.left=X; // X= number of pixels of separation from the left component
panel.add(label,constraints);
Note that i have omitted a lot of configuration properties in the setup of the constraints, you better read the documentacion of GridBagLayout
请注意，我在约束的设置中省略了很多配置属性，您最好阅读GridBagLayout的文档
