本文介绍了一个名为CrossInfoExt的卡口扩展类及其关联的方法setChildren。该类用于表示具有层级结构的数据，并提供了设置子节点的功能。每个实例代表一个卡口信息节点，包含ID、名称等属性。

public void setChildren(CrossInfoExt crossTree, List<CrossInfoExt> lists){

    List<CrossInfoExt> lists1 = new ArrayList<>();
    for(CrossInfoExt crossInfoExt : lists){

        if(crossTree.getId() == crossInfoExt.getParentId()){
            if(crossInfoExt.getIsLeaf() == 0){
                setChildren(crossInfoExt,lists);
            }
            lists1.add(crossInfoExt);
        }
    }
    crossTree.setChildren(lists1);

}
