构建Tree对象

@Data
public  class Tree<T> {

    //节点ID
    private String id;
    //父ID
    private String parentid;
    //显示节点文本
    private String title;
 
    //是否有父节点
    private boolean hasParent = false;
    //是否有子节点
    private boolean hasChildren = false;
    
    //节点属性
    private Map<String, Object> attributes;
    //节点的子节点
    private List<Tree<T>> children;
    //节点是否被选中 true false
    private boolean checked = false;
  }

存入方式：找到根节点，根据根节点找list子节点，再迭代子节点
