这就成功了 为了更好的帮助&更快，考虑发布一个代码是相当损坏的一个是诚实的，但在这里你…抱歉损坏代码……仍然在学习阶段…我的观点是……在这里做什么，以便我的点击事件取代UI实例的UpPutpGe1实例在JSP公共空隙鼠标（MouthEngult）{if（e.getSource（）==ui.loadTemplate）{jsp.setViewportView（op1）；jsp.setVisible（false）；op1.setVisible（true）；jsp.getViewport（）.revalidate（）；//新建演示（）；//jsp.getViewport（）.repaint（）；}}您应该为变量找到更好的名称。p1没有传达其含义，firstPanel或panelOne会更好。一般来说，您应该更加注意可读性
