package com.zetcode;

import javax.swing.BorderFactory;
import javax.swing.JButton;
import javax.swing.JComponent;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JTextArea;
import javax.swing.SwingUtilities;
import net.miginfocom.swing.MigLayout;

public class CustomerDetailsMigLayoutEx extends JFrame {

    public CustomerDetailsMigLayoutEx() {

        initUI();
    }

    private void initUI() {

        JLabel custId1 = new JLabel("Cust Id");
        JLabel custId2 = new JLabel("A52501235");

        JLabel name1 = new JLabel("Name");
        JLabel name2 = new JLabel("Joe Beer");

        JLabel address1 = new JLabel("Address");
        JLabel address2 = new JLabel("112, 1st Street, City, State, Country");

        JLabel orders = new JLabel("<html><u style='font-size:13px'>Last 3 Orders</u></html>");

        JLabel date1 = new JLabel("11 Dec 2015");
        JLabel date2 = new JLabel("17 Dec 2015");
        JLabel date3 = new JLabel("19 Dec 2015");

        JTextArea area1 = new JTextArea(7, 28);
        area1.setBorder(BorderFactory.createEtchedBorder());

        JTextArea area2 = new JTextArea(7, 28);
        area2.setBorder(BorderFactory.createEtchedBorder());

        JTextArea area3 = new JTextArea(7, 28);
        area3.setBorder(BorderFactory.createEtchedBorder());

        JTextArea area4 = new JTextArea(7, 28);
        area4.setBorder(BorderFactory.createEtchedBorder());        

        JButton btn1 = new JButton("Submit");
        JButton btn2 = new JButton("Cancel");

        createLayout(custId1, custId2, name1, name2, address1, address2, 
                orders, date1, area1, date2, area2, date3, area3, 
                area4, btn1, btn2);

        setTitle("MigLayout example");
        setLocationRelativeTo(null);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }

    private void createLayout(JComponent... arg) {

        setLayout(new MigLayout("insets dialog, align 50% 50%, gap 5lp 7lp"));

        add(arg[0], "split 2, sgx");
        add(arg[1], "gapx 15lp, wrap");
        add(arg[2], "split 2, sgx");
        add(arg[3], "gapx 15lp, wrap");
        add(arg[4], "split 2, sgx");
        add(arg[5], "gapx 15lp, wrap");        
        add(arg[6], "gapy unrel, wrap");
        add(arg[7], "gapy rel, split 2");
        add(arg[8], "wrap");
        add(arg[9], "split 2");
        add(arg[10], "wrap");
        add(arg[11], "split 2");
        add(arg[12], "wrap");
        add(arg[13], "growx");        
        add(arg[14], "split 2, flowy");    
        add(arg[15]);    
        pack();
    }

    public static void main(String[] args) {

        SwingUtilities.invokeLater(() -> {
            CustomerDetailsMigLayoutEx ex = new CustomerDetailsMigLayoutEx();
            ex.setVisible(true);
        });
    }
}

为了执行您的布局类型，可以使用GridBagLayout或GroupLayout

这里有一个了解布局的有用链接：https://docs.oracle.com/javase/tutorial/uiswing/layout/visual.html

如图所示，您需要有一些列（按行2列）

为此，
GridBagLayout通过将组件放置在单元格网格内来对齐组件
而GroupLayout则分别处理水平和垂直布局。布局是为每个标注独立定义的

因此，对于您的示例，您必须定义3个面板（CustInfo、Lastorders和Notes），由一个组或GridBagLayout定义
