java中的水平和垂直滚动条

我有一个文档比较程序，它使用xwpfdocumentapachepoi将.docx文件显示到文本区域。我需要在textarea中添加一个滚动条，因为我创建了一个固定高度和宽度的textarea。因此，在文本区域中无法看到超过文本的高度和宽度的文件。我研究了一些代码，并提出了这些代码

    JTextArea textAreaFile1 = new JTextArea();
    textAreaFile1.setEditable(false);
    JScrollPane scroll = new JScrollPane ( textAreaFile1 );
    scroll.setViewportView(textAreaFile1);
    scroll.setVerticalScrollBarPolicy ( ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS );

我不知道如何将其呈现到我的组布局中。我使用WindowBuilder创建GUI，因为代码是自动生成的，我不知道如何将其添加到自动生成的代码中。下面是布局的代码

GroupLayout groupLayout = new GroupLayout(frmOverallResults.getContentPane());
    groupLayout.setHorizontalGroup(
        groupLayout.createParallelGroup(Alignment.LEADING)
            .addGroup(groupLayout.createSequentialGroup()
                .addContainerGap()
                .addGroup(groupLayout.createParallelGroup(Alignment.LEADING)
                    .addGroup(groupLayout.createSequentialGroup()
                        .addComponent(textAreaFile1, GroupLayout.PREFERRED_SIZE, 371, GroupLayout.PREFERRED_SIZE)
                        .addGap(18))
                    .addGroup(groupLayout.createSequentialGroup()

我知道我不应该使用window builder并手动创建它。有什么想法吗？

我能给你的任何答案都是关于更换裁员经理，这显然不是一个小工作。另一个解决方案是返回WindowBuilder，确保将文本区域添加到视图中的滚动窗格中
