根据节点递归出子集

根据节点，查询出所有子节点（递归）

public List<BudgetCbs> treeBudgetCbsList(List<BudgetCbs> budgetCbsList, String pid) {
        //子节点
        List<BudgetCbs> childBudgetCbs = new ArrayList<BudgetCbs>();
        treeBudgetCbsList1(childBudgetCbs, budgetCbsList, pid);
        return childBudgetCbs;
    }
    public List<BudgetCbs> treeBudgetCbsList1(List<BudgetCbs> childBudgetCbs, List<BudgetCbs> budgetCbsList, String pid) {
        for (BudgetCbs bc : budgetCbsList) {
            //遍历出父id等于参数的id，add进子节点集合
            if (org.apache.commons.lang3.StringUtils.isNotBlank(bc.getParent())) {
                if (bc.getParent().equals(pid)) {
                    //递归遍历下一级
                    treeBudgetCbsList1(childBudgetCbs, budgetCbsList, bc.getDataId());
                    childBudgetCbs.add(bc);
                }
            }
        }
        return childBudgetCbs;
    }
