Springboot 在 Java 给 Java 开发带来了极大的便利，那么如何把它集成到 Swing GUI 编程项目中，使得 GUI 编程更加高效？本人简单做了一下尝试，完成一个 demo ，贴出来供大家参考

具体步骤

创建一个 spring boot 项目

这步就不需要多说了，大家参考 spring 官网的初始化工具，自行搞一个。

在 eclipse 中安装 Swing 设计工具

这步也相对比较简单，大家随便找个博客照抄就可以。

Spring 上下文工具类

这个有什么用呢？后面会讲，先上代码

package com.example.demo.context;import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;public class SpringContext implements ApplicationContextAware {private static ApplicationContext context = null;@Overridepublic void setApplicationContext(ApplicationContext applicationContext) throws BeansException {context = applicationContext;}public static ApplicationContext getContext() {return context;}
}

应用程序上下文工具类

同样，下文会看到怎么用，还是先上代码

package com.example.demo.context;import javax.swing.JFrame;
import org.springframework.boot.context.event.ApplicationStartedEvent;
import org.springframework.context.ApplicationListener;
import com.example.demo.view.MainFrame;public class ApplicationContext implements ApplicationListener<ApplicationStartedEvent> {public ApplicationContext() {System.out.println("ApplicationContext is inited..");}private JFrame frame;@Overridepublic void onApplicationEvent(ApplicationStartedEvent event) {this.updateContent(MainFrame.getInstance());}public void updateContent(JFrame _frame) {if(this.frame != null) {this.frame.setVisible(false);}this.frame = _frame;this.frame.setVisible(true);}
}

写一个登录的 Frame

package com.example.demo.view;import java.awt.EventQueue;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.border.EmptyBorder;import com.example.demo.context.ApplicationContext;
import com.example.demo.context.SpringContext;public class LoginFrame extends JFrame {private static final long serialVersionUID = 1L;private JPanel contentPane;private static LoginFrame instance;public static LoginFrame getInstance() {if(instance == null) {instance = new LoginFrame();}return instance;}/*** Launch the application.*/public static void main(String[] args) {EventQueue.invokeLater(new Runnable() {public void run() {try {LoginFrame frame = new LoginFrame();frame.setVisible(true);} catch (Exception e) {e.printStackTrace();}}});}/*** Create the frame.*/public LoginFrame() {setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);setBounds(100, 100, 450, 300);contentPane = new JPanel();contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));setContentPane(contentPane);JButton btnNewButton = new JButton("New button");btnNewButton.addActionListener(new ActionListener() {public void actionPerformed(ActionEvent e) {SpringContext.getContext().getBean(ApplicationContext.class).updateContent(new MainFrame());}});contentPane.add(btnNewButton);}}

写一个主业务 Frame

package com.example.demo.view;import java.awt.BorderLayout;
import java.awt.Component;
import java.awt.EventQueue;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;import javax.swing.JFrame;
import javax.swing.JMenu;
import javax.swing.JMenuBar;
import javax.swing.JMenuItem;
import javax.swing.JPanel;
import javax.swing.border.EmptyBorder;import com.example.demo.context.ApplicationContext;
import com.example.demo.context.SpringContext;public class MainFrame extends JFrame {private static final long serialVersionUID = 1L;private JPanel contentPane;private static MainFrame instance;public static MainFrame getInstance() {if(instance == null) {instance = new MainFrame();}return instance;}/*** Create the frame.*/protected MainFrame() {setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);setBounds(100, 100, 450, 300);JMenuBar menuBar = new JMenuBar();setJMenuBar(menuBar);JMenu mnNewMenu = new JMenu("系统");menuBar.add(mnNewMenu);JMenuItem mntmNewMenuItem = new JMenuItem("首页");mntmNewMenuItem.addActionListener(menuClick);mnNewMenu.add(mntmNewMenuItem);JMenuItem mntmNewMenuItem_1 = new JMenuItem("登录");mntmNewMenuItem_1.addActionListener(menuClick);mnNewMenu.add(mntmNewMenuItem_1);contentPane = new JPanel();contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));setContentPane(contentPane);contentPane.setLayout(new BorderLayout(0, 0));}private void clearMainPanel() {Component[] cps = contentPane.getComponents();if(cps.length<=0) {return;}for(int i=0;i<cps.length;i++) {contentPane.remove(i);}}public static void main(String ...args) {EventQueue.invokeLater(new Runnable() {public void run() {try {MainFrame frame = new MainFrame();frame.setVisible(true);} catch (Exception e) {e.printStackTrace();}}});}private ActionListener menuClick = new ActionListener() {@Overridepublic void actionPerformed(ActionEvent e) {System.out.println(e.getActionCommand());if("登录".equals(e.getActionCommand())) {SpringContext.getContext().getBean(ApplicationContext.class).updateContent(LoginFrame.getInstance());}}};
}
