Java 点击按钮，通过jtextpane显示数据

我现在有下面的swing表单，请您告知我希望生成并存储在StringWriter中的xml，我希望在点击名为generate的按钮时，相同的字符串显示在jtextpane本身中。请告知如何实现此目的

我不确定我是否理解正确，但如果您只想在按下按钮后向JTextField添加字符串，则应使用以下命令：

button.addActionListener(new ActionListener() 
{
        @Override
        public void actionPerformed(ActionEvent e)
        {
               textField.setText(yourString);
        }
});

---

请记住，您的文本字段应该是最终的，上面的代码只是实现这一点的一种方法。您还可以创建一个新类，该类实现ActionListener接口，并可以访问要在组件中双关的按钮、jtextfield和字符串

添加路由类。这可能不是必需的，但如果不运行代码，就很难解释该做什么。
