Spring Layout未正确调整大小

我是Java GUI构建中的Spring布局的新手,但是如果我想按照我想要的方式布局GUI,似乎使用spring布局是唯一的方法。

我遇到的问题是,当我在JFrame上将resizable设置为false时,我的GUI面板之一扩展了一个像素或2。但是当我将resizeable设置为true时,一切都按照我想要的方式完美排列。我知道1或2像素并没有太多关闭,但它足以使我的GUI看起来很奇怪,因为有些文本框比其他文本框拉伸了1或2个像素。这是我的春季布局的代码:

    pnlTop.setLayout(layout);

    lblClosetLoc.setText("Closet location:");
    lblPhone1.setText("Phone 1:");
    lblJackPaired.setText("Jack paired:");
    lblPhone2.setText("Phone 2:");
    lblCubicle.setText("Cubicle:");
    lblJackType.setText("Jack type:");
    lblName.setText("Name:");
    lblPhoneJack1.setText("Phone jack 1:");
    lblPhoneJack2.setText("Phone jack 2:");
    lblDataJack1.setText("Data jack 1:");
    lblDataJack2.setText("Data jack 2:");
    lblComments.setText("Comments:");

    txtClosetLoc.setEditable(false);
    txtClosetLoc.setText("");
    txtPhone1.setEditable(false);
    txtPhone1.setText("");

    txtPhone2.setEditable(false);
