级联树SELECTTREE格式调整

步骤：

1、将全部列表设置成Map<Long, List<Obejct>> map的格式，方便查看每个父级对应的子列表，减少循环次数

2、对这个map进行递归，重新进行级联树的集合调整，将子集放置在对应的childs里面。

    public DynamicDeployTable selectDynamicDeployTableTree(String formCode) {
        log.info("selectDynamicDeployTableTree：{}", formCode);
        // 顶级父节点
        DynamicDeployTable returnDynamicDeployTable = null;
        List<DynamicDeployTable> dynamicDeployTableList = selectDynamicDeployTableList(formCode);
        Map<Long, List<DynamicDeployTable>> dynamicDeployTableMap = new HashMap<>();

        for (DynamicDeployTable dynamicDeployTable : dynamicDeployTableList) {
            Long parentId = dynamicDeployTable.getParentId();
            if (parentId == 0L) {
                returnDynamicDeployTable = dynamicDeployTable;
                continue;
            }
            List<DynamicDeployTable> dynamicDeployTables = dynamicDeployTableMap.get(parentId);
            if (ObjectUtil.isNotEmpty(dynamicDeployTables)) {
                dynamicDeployTables.add(dynamicDeployTable);
            } else {
                dynamicDeployTables = ListUtil.createList();
                dynamicDeployTables.add(dynamicDeployTable);
                dynamicDeployTableMap.put(parentId, dynamicDeployTables);
            }
        }
        recursionFn(dynamicDeployTableMap, returnDynamicDeployTable);
        return returnDynamicDeployTable;
    }

    /**
     * 递归列表
     *
     * @param dynamicDeployTableMap 全部列表
     * @param parentDynamicDeployTable 父级对象
     */
    private void recursionFn(Map<Long, List<DynamicDeployTable>> dynamicDeployTableMap, DynamicDeployTable parentDynamicDeployTable) {
        List<DynamicDeployTable> dynamicDeployTables = dynamicDeployTableMap.get(parentDynamicDeployTable.getDynamicId());
        if (ObjectUtil.isEmpty(dynamicDeployTables)) {
            return;
        }
        parentDynamicDeployTable.setChildren(dynamicDeployTables);
        for (DynamicDeployTable deployTable : dynamicDeployTables) {
            recursionFn(dynamicDeployTableMap, deployTable);
        }
    }

2.根据根节点设置

    public List<WmsMaterialClass> getMaterialClassTreeList(WmsMaterialClassVo materialClassVo) {
        log.info("getMaterialClassTreeList,INPUT:{}", JSONObject.toJSONString(materialClassVo));
        List<WmsMaterialClass> initList = getMaterialClassList(materialClassVo);
        if (ObjectUtils.isEmpty(initList)) {
            return ListUtil.createList();
        }
        Map<Long, List<WmsMaterialClass>> matClasChildMap = new HashMap<>();
        for (WmsMaterialClass item : initList) {
            Long parentId = item.getParentId();
            List<WmsMaterialClass> materialClasses = matClasChildMap.get(parentId);
            if (ObjectUtil.isEmpty(materialClasses)) {
                materialClasses.add(item);
                matClasChildMap.put(parentId, materialClasses);
            } else {
                materialClasses.add(item);
            }
        }
        List<WmsMaterialClass> rootNodes = matClasChildMap.get(0L);
        if (ObjectUtils.isEmpty(rootNodes)) {
            return ListUtil.createList();
        }
        for (WmsMaterialClass rootNode : rootNodes) {
            childTree(matClasChildMap,rootNode);
        }
        return rootNodes;
    }

    private void childTree(Map<Long, List<WmsMaterialClass>> matClasChildMap,WmsMaterialClass node) {
        Long nodeId = node.getId();
        List<WmsMaterialClass> children = matClasChildMap.get(nodeId);
        if (!ObjectUtils.isEmpty(children)) {
            node.setChildren(children);
            for (WmsMaterialClass child : children) {
                childTree( matClasChildMap,child);
            }
        }
    }
