英文:
Exported swing project not displaying properly
问题
我最近一直在尝试使用Swing（初学者），在为朋友制作一个应用程序时遇到了问题。我使用的是IDEA IDE，布局和所有的框架都显示正常，但当我使用Maven导出项目时，jar文件显示的布局中缺少了面板和按钮。
我的框架源代码如下：
（注意：我删除了所有其他的方法，因为它们没有修改布局（只有其他对象的getter和setter），我还删除了按钮的actionCalls和其他类似的代码。）
public class OOBFrame extends JFrame {
// ...（你的代码继续）
public OOBFrame(String title) {
super(title);
setLayout(new GridBagLayout());
GridBagConstraints gc = new GridBagConstraints();
c.setBackground(Gui.BACKGROUND);
c.setLayout(new GridBagLayout());
c.setPreferredSize(Gui.getMonitorSize());
// ...（你的代码继续）
validate();
pack();
setExtendedState(JFrame.MAXIMIZED_BOTH);
setVisible(false);
}
}
谢谢你提供关于我可能做错了什么的任何见解。
该框架在应用程序的上一个窗口中也使用了setVisible(true)，所以这不是问题。
如果需要，我可以提供其他标签和面板的任何代码，或者整个项目的代码。
编辑后：
运行jar的控制台输出。
D:\GitProjects\KSP-NoU-Battle System 3\target>java -cp Battle_Simulator_3.0-1.0.0.0.jar impl.App
java.nio.file.NoSuchFileException: database.csv
[ERR 17:02:24] java.nio.file.NoSuchFileException: countermeasures.txt
[ERR 17:02:24] java.nio.file.NoSuchFileException: weapons.txt
[LOG 17:02:24] Crafts saved: [0]
然后日志结束，但应用程序的第一个窗口启动。然后是错误的窗口。
解决方案：应用程序缺少资源文件，导致面板无法加载。

I have been experimenting with Swing lately (beginner) and while trying to make one application for a friend, I encountered a problem. I am using IDEA IDE and the layout and all frames displays properly, but when I export the project using maven, the jar file shows the layout with missing panels and buttons.
My source code for the frame is:
(Note: I removed all other methods as they have not been modifying the layout (only getters and setters for other objects and I also removed actionCalls and other such code for the buttons.)
public class OOBFrame extends JFrame {
private final Container c = getContentPane();
private final DefaultListModel<Craft> textForWhite = new DefaultListModel<>();
private final DefaultListModel<Craft> textForBlack = new DefaultListModel<>();
private final JCraftList<Craft> whiteListedCrafts = new JCraftList<>(textForWhite);
private final JCraftList<Craft> blackListedCrafts = new JCraftList<>(textForBlack);
private final JScrollPane scrollerWhite = new JScrollPane(whiteListedCrafts);
private final JScrollPane scrollerBlack = new JScrollPane(blackListedCrafts);
private final SortedMap<Craft, ArrayList<JButton>> templateButtons = new TreeMap<>();
private final JButton nextScreen = new JButton("Finish");
private final JButton editing = new JButton("Edit selected");
private final ArrayList<Craft> selectedCraftsFromList = new ArrayList<>();
private JCraftPanel details;
private final GridBagConstraints gcDetails;
private JList<Craft> lastSelectedList;
public OOBFrame(String title) {
super(title);
setLayout(new GridBagLayout());
GridBagConstraints gc = new GridBagConstraints();
c.setBackground(Gui.BACKGROUND);
c.setLayout(new GridBagLayout());
c.setPreferredSize(Gui.getMonitorSize());
gc.gridx = 0;
gc.gridy = 0;
gc.fill = GridBagConstraints.HORIZONTAL;
gc.anchor = GridBagConstraints.NORTH;
gc.gridwidth = 6;
getContentPane().add(new JMenuExt(1), gc);
whiteListedCrafts.setBackground(Gui.BACKGROUND);
whiteListedCrafts.setForeground(Color.WHITE);
blackListedCrafts.setBackground(Gui.BACKGROUND);
blackListedCrafts.setForeground(Color.WHITE);
gc = new GridBagConstraints();
gc.gridheight = OOB.TEMPLATE.getCrafts().size();
gc.fill = GridBagConstraints.BOTH;
gc.weighty = 4;
gc.weightx = 1;
gc.gridx = 0;
gc.gridy = 1;
getContentPane().add(scrollerWhite, gc);
gc.gridx = 4;
gc.gridwidth = 2;
getContentPane().add(scrollerBlack, gc);
gc.fill = GridBagConstraints.HORIZONTAL;
gc.gridwidth = 1;
gc.gridheight = 1;
gc.gridy = 0;
gc.gridx = 1;
gc.weightx = 0.1;
for (Craft craft : OOB.TEMPLATE.getCrafts()) {
++gc.gridy;
templateButtons.put(craft, new ArrayList<>());
templateButtons.get(craft).add(new JButton("+"));
templateButtons.get(craft).add(new JButton("+"));
c.add(templateButtons.get(craft).get(0), gc);
++gc.gridx;
gc.weightx = 8;
JLabel newLabel = new JLabel(craft.getName());
newLabel.setForeground(Gui.FOREGROUND);
newLabel.setHorizontalAlignment(SwingConstants.CENTER);
newLabel.setPreferredSize(new Dimension(200, 20));
c.add(newLabel, gc);
gc.weightx = 0.1;
++gc.gridx;
c.add(templateButtons.get(craft).get(1), gc);
gc.gridx -= 2;
templateButtons.get(craft).get(0).addActionListener(e -> {
Craft newCraft = craft.copy(Side.WHITE);
OOB.WHITE.addCraft(newCraft);
textForWhite.addElement(newCraft);
whiteListedCrafts.updateUI();
});
templateButtons.get(craft).get(1).addActionListener(e -> {
Craft newCraft = craft.copy(Side.BLACK);
OOB.BLACK.addCraft(newCraft);
textForBlack.addElement(newCraft);
blackListedCrafts.updateUI();
});
}
gc.anchor = GridBagConstraints.SOUTH;
++gc.gridy;
++gc.gridy;
gc.gridx = 5;
gc.fill = GridBagConstraints.BOTH;
//nextScreen.setPreferredSize(new Dimension(200, 100));
getContentPane().add(nextScreen, gc);
details = new JCraftPanel(" ", selectedCraftsFromList, false);
gcDetails = new GridBagConstraints();
gcDetails.gridx = 0;
gcDetails.gridy = gc.gridy;
gcDetails.gridwidth = 4;
gcDetails.gridheight = 2;
gcDetails.weighty = 2;
gcDetails.fill = GridBagConstraints.BOTH;
add(details, gcDetails);
setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
validate();
pack();
setExtendedState(JFrame.MAXIMIZED_BOTH);
setVisible(false);
}
}
Thank you for any insight of what I could do wrong.
The Frame is also setVisible(true) in previous frame of the application, so that is not an issue.
I can provide any code of other labels and panels if needed or the whole project.
Edited:
Console run of the jar.
D:\GitProjects\KSP-NoU-Battle System 3\target>java -cp Battle_Simulator_3.0-1.0.0.0.jar impl.App
java.nio.file.NoSuchFileException: database.csv
[ERR 17:02:24] java.nio.file.NoSuchFileException: countermeasures.txt
[ERR 17:02:24] java.nio.file.NoSuchFileException: weapons.txt
[LOG 17:02:24] Crafts saved: [0]
Then the log ends but the application first window starts. Followed by the wrong window.
Solved: Application was missing resource files resulting in non-loadable panels.
