您可以为 UIDefaults 设置新值：

        UIDefaults def = UIManager.getLookAndFeelDefaults();
        def.put( "TabbedPane.foreground", Color.RED );
        def.put( "TabbedPane.textIconGap", new Integer(16) );
        def.put( "TabbedPane.background", Color.BLUE );
        def.put( "TabbedPane.tabInsets", new Insets(10,10,10,10) );
        def.put( "TabbedPane.selectedTabPadInsets", new Insets(10,20,10,20) );

这是密钥列表

TabbedPane.textIconGap
TabbedPane.contentOpaque
TabbedPane.focus
TabbedPane.foreground
TabbedPane.tabRunOverlay
TabbedPane.shadow
TabbedPane.darkShadow
TabbedPane.background
TabbedPane.ancestorInputMap
TabbedPane.focusInputMap
TabbedPane.tabInsets
TabbedPane.light
TabbedPane.contentBorderInsets
TabbedPane.tabsOverlapBorder
TabbedPane.tabsOpaque
TabbedPane.tabAreaInsets
TabbedPane.highlight
TabbedPane.font
TabbedPane.selectedTabPadInsets

对于 Nimbus LookAndFeel，还有一些其他Nimbus 默认值，例如：

      TabbedPane:TabbedPaneTabArea.contentMargins
      TabbedPane:TabbedPaneTabArea[Enabled].backgroundPainter
      TabbedPane:TabbedPaneTab[Selected].backgroundPainter
      TabbedPane:TabbedPaneTabArea[Enabled].backgroundPainter
      TabbedPane:TabbedPaneTab.contentMargins
      TabbedPane.tabOverlap

更改选项卡高度和宽度的一种方法是在选项卡的标签中使用 HTML 和/或 CSS。为此，您可以在 HTML 'span' 或 'p' 元素中使用 CSS 填充属性。

您可以按如下方式控制高度：

JTabbedPane tabs = new JTabbedPane();
tabs.setUI(new BasicTabbedPaneUI() {
    @Override
    protected int calculateTabHeight(int tabPlacement, int tabIndex, int fontHeight) {
        return 45; // manipulate this number however you please.
    }
});

如果每个选项卡需要不同的高度，这个答案也可能有用：How to handle the height of the tab title in JTabbedPane
