生成树结构数据

private List<SysDept> getChild(int parentKey, List<SysDept> deptList) {
        List<SysDept> childrenList = new ArrayList();
        if (!CollectionUtils.isEmpty(deptList)) {
            Iterator var4 = deptList.iterator();

            SysDept node;
            while(var4.hasNext()) {
                node = (SysDept)var4.next();
                if (Objects.equals(node.getDeptParentId(), parentKey)) {
                    childrenList.add(node);
                }
            }

            var4 = childrenList.iterator();

            while(var4.hasNext()) {
                node = (SysDept)var4.next();
                List<SysDept> child = this.getChild(node.getDeptId(), deptList);
                List<SysDept> old = node.getChildren();
                old.addAll(child);
                node.setChildren(old);
            }
        }

        return childrenList;
    }
