Java에서 JSON 파일을 구문 분석 중입니다. Jackson이나 GSON이 아닌 JSON을 정리하십시오. 제 문제는 새로운 .json 파일을로드 할 때 JTree가 새로 고쳐지지 않는다는 것입니다. stackoverflow 및 다른 포럼에서 발견 한 여러 가지 옵션을 시도했지만 솔루션을 찾지 못했습니다.JTree가 새로 고침되지 않고 새로운 JSON을로드 한 후 제어가 작동하지 않습니다.
아래 코드를 작성하겠습니다.
NodeStorage, NodeEntity 등은 DefaultMutableTreeNode를 상속받은 NodeInfo의 하위 클래스입니다.
ViewTree는 DefaultTreeModel을 확장합니다.
특별히 찾아해야코드 기능은 내가 여기를 작성하고 코드의 나머지 부분 (전체 GUI 클래스가 다른 창에서이 클래스 아래에 기록됩니다) initialiseTree입니다 :
public void initialiseTree() throws IOException, JSONException {
this.setScrollPane(null);
this.setJtree(null);
this.setViewTree(null);
if(this.getPathMetaschema() == null) {
this.setNodeStorage(new NodeStorage(new ModelStorage("Empty root", "emptroot", null)));
}
else {
JSONinit(pathMetaschema);
setNodeStorage(new NodeStorage(this.getModelStorage()));
}
this.setViewTree(new ViewTree(this.getNodeStorage()));
this.getViewTree().setMyRoot(this.getNodeStorage());
this.getViewTree().reload(this.getNodeStorage());
this.getViewTree().nodeChanged(this.getViewTree().getMyRoot());
// this.getViewTree().addTreeSelectionListener(new ControllerTree(this));
// TODO: OVO NIJE BILO OVDE VEC JE BILO U INICIJALIZACIJI POCETNOJ. RESITI PROBLEM.
setJtree(new JTree(this.getViewTree()));
jtree.setEditable(true);
DefaultMutableTreeNode currentNode = (DefaultMutableTreeNode) this.getViewTree().getRoot();
do {
if (currentNode.getLevel()==1)
jtree.expandPath(new TreePath(currentNode.getPath()));
currentNode = currentNode.getNextNode();
}
while (currentNode != null);
// jtree.setExpandsSelectedPaths(false);
jtree.getSelectionModel().setSelectionMode(TreeSelectionModel.SINGLE_TREE_SELECTION);
scrollPane = new JScrollPane(this.getJtree());
add(scrollPane, BorderLayout.WEST);
getJtree().setCellRenderer(new MyTreeCellRenderer());
SwingUtilities.updateComponentTreeUI(this.getJtree());
// scrollPane.repaint();
// this.getJtree().repaint();
// this.repaint();
// this.revalidate();
// this.validate();
}

누군가가 이에 대한 답변을 얻길 바랍니다. 저는 GUI를하고 싶지 않습니다. 특히 스윙이 아닙니다. 저는 백엔드 녀석입니다.
고마워요! :)
