使用hutool的树结构工具时,其内置的TreeNode类只有固定的几个属性,想添加自定义属性怎么办?
文档中给出了自定义字段名的方法,但是自定义的字段名还是不能从每个TreeNode结点中获取
我的解决方法是新建一个结点类继承TreeNode,添加自定义属性,并实现构造方法
@Data public class LayerTopicTreeNode extends TreeNode<String> { private String code; private String name; private Integer weight; private String description; private String icon; private String pCode; private Integer resourceCount; public LayerTopicTreeNode(){} public LayerTopicTreeNode(String code,String name,String description,String icon,String pCode,Integer resourceCount,Integer weight){ super(code,pCode,name,weight); this.code = code; this.name = name; this.weight = weight; this.description = description; this.icon = icon; this.pCode = pCode; this.resourceCount = resourceCount; } }
在添加结点集合时使用自定义的这个节点类
这样在构建时就可以从node结点中获取自定义的字段值
