我在下面的代码中遇到了itemTree.stopEditing()的问题.

我可以很好地编辑设备.编辑将节点文本从IP地址更改为beIP地址+主机名(使字符串更长).问题是,编辑后,JTree显示IP后跟"..."

看起来Tree没有更新它的UI.我以为使用树的编辑功能会自动更新UI？我该怎么办？

this.setShowsRootHandles(true);
this.addMouseListener(new MouseAdapter() {
    @Override
    public void mousePressed(MouseEvent e) {
        System.out.println("\n[MyItemTree]mousePressed");
        MyItemTree itemTree = (MyItemTree) e.getSource();
        TreePath tp = itemTree.getPathForLocation(e.getX(), e.getY());
        Rectangle pathBounds = itemTree.getUI().getPathBounds(itemTree, tp);
        TreePath[] selectionPaths = itemTree.getSelectionPaths();//what if this is empty?
        Object lastPathComponent = tp.getLastPathComponent();// what if this is empty?
        digOutNodesForSelection((DefaultMutableTreeNode) lastPathComponent, itemTree);
        itemTree.setEditable(true);

        ArrayList<DefaultMutableTreeNode> nodes = new ArrayList();
        for (int i = 0; i < selectionPaths.length; i++) {
            Object lastPathComponent1 = selectionPaths[i].getLastPathComponent();
            //Should only be adding the Leaf Nodes here
            if (lastPathComponent1 instanceof …

我有这个字符串.我试图从每个条目拉出接口,nameif和安全级别.

我的 HashSet 包含多个具有相同 HashCode 的“AccessRequest”。我只希望有一个实例。我不认为具有相同 HashCode 的项目可以出现在 HashSet 中。我在这里做错了什么？

更新：基于 HashSet 只保留一个不等于列表中另一个项目的假设，并且也许我的 equals/hash 方法需要简化，我已经更新了我的问题。我仍然收到多个在我的哈希集中评估为等于的项目。

以下是“AccessRequest”中的 HashCode 和 Equals 方法

更新：我更新了我的哈希值，等于只有我需要“等于”的必要字段

    @Override
public int hashCode() {
    int hash = 5;
    hash = 79 * hash + Objects.hashCode(this.targets);
    hash = 79 * hash + Objects.hashCode(this.sources);
    hash = 79 * hash + Objects.hashCode(this.destinations);
    hash = 79 * hash + Objects.hashCode(this.services);
    hash = 79 * hash + Objects.hashCode(this.action);
    return hash;
}

@Override
public boolean equals(Object obj) {
    if (this == obj) {
        return true; …
