之前写过一篇用stream流实现查询树型结构的文章，现在以hutool中的TreeUtil再来实现一次，之前的帖子Java Stream流实现递归查询树型结构
查询出所有数据，用父节点递归查询出所有子节点数据
/**
* 封装备注分类集合
*
* @param remarkTypeList 备注分类集合
* @return 递归好的集合
*/
@Override
public List<Tree<String>> queryTreeList(List<RemarkType> remarkTypeList) {
//配置
TreeNodeConfig treeNodeConfig = new TreeNodeConfig();
treeNodeConfig.setIdKey("remarkTypeId");
treeNodeConfig.setNameKey("typeName");
treeNodeConfig.setParentIdKey("parentId");
// 最大递归深度
treeNodeConfig.setDeep(3);
//转换器
return TreeUtil.build(remarkTypeList, "0", treeNodeConfig,
(treeNode, tree) -> {
tree.setId(treeNode.getRemarkTypeId().toString());
tree.setParentId(treeNode.getParentId().toString());
tree.setName(treeNode.getTypeName());
tree.putExtra("displayStatus",treeNode.getDisplayStatus());
tree.putExtra("sort",treeNode.getSort());
tree.putExtra("contactWay",treeNode.getContactWay());
});
}
查询结果:
