java如何实现递归删除树形数据的任一个节点

Connection connection = JDBCUtil_C3P0.getConnection();

try {
//关闭事务自动提交(开启事务)
connection.setAutoCommit(false);
//...你的操作
//以上全部操做无异常则提交事务
connection.commit();
} catch (SQLException e) {
	//一旦事务中有哪一步操做发生异常则进行事务回滚
	connection.rollback();
	e.printStackTrace();
}finally{
	//关闭链接资源
	//...
}

     * @param id 待删除节点的id

    public ResponseData<Boolean> deleteTreeNodeById(@RequestParam(name = "id") String id) {
        return successWithData(configDictService.deleteTreeNodeById(id));
    }

boolean deleteTreeNodeById(String id);

    @Override
    public boolean deleteTreeNodeById(String id) {
        List<String> deleteIdList = new LinkedList<>();
        deleteIdList.add(id);
        getAllChildrenIdList(id, deleteIdList);
        return baseMapper.deleteBatchIds(deleteIdList) == 1;
    }
