private JTree getJTree() {
  if (jTree == null) {
   jTree = new JTree();
   DefaultTreeModel treeModel=null;
   DefaultMutableTreeNode parent=new DefaultMutableTreeNode("车队信息");
   DefaultMutableTreeNode node1=new DefaultMutableTreeNode("车队1");
   DefaultMutableTreeNode node2=new DefaultMutableTreeNode("京H8888");
   DefaultMutableTreeNode node3=new DefaultMutableTreeNode("京J5619");
   DefaultMutableTreeNode node4=new DefaultMutableTreeNode("车队2");
   DefaultMutableTreeNode node5=new DefaultMutableTreeNode("冀C66155");
   DefaultMutableTreeNode node6=new DefaultMutableTreeNode("冀F88088");
   treeModel=new DefaultTreeModel(parent);



   treeModel.insertNodeInto(node1,parent,parent.getChildCount());
   treeModel.insertNodeInto(node2,node1,node1.getChildCount());
   treeModel.insertNodeInto(node3, node1,node1.getChildCount());
   treeModel.insertNodeInto(node4, parent,parent.getChildCount());
   treeModel.insertNodeInto(node5, node4,node4.getChildCount());
   treeModel.insertNodeInto(node6, node4, node4.getChildCount());

   jTree=new JTree(treeModel);
   jTree.setVisible(true);
  }
  return jTree;
}
