mysql 存储过程，以及mybatis如何调用

begin
     declare cargoSourceId varchar(20);
    
     declare done int;
     declare cur_test CURSOR for select cargo_source_id from orders where order_status = '10' and datediff(NOW(),update_time)>=3;
     declare continue handler FOR SQLSTATE '02000' SET done = 1;
     
         open cur_test;
         repeat
             fetch cur_test into cargoSourceId;
                         # 将要取消的失效对于的货源全部更新为“未下单”状态
             update cargo_source set is_ordered=0,update_time=now() where id=cargoSourceId;
         until done end repeat;
         close cur_test;
            # 失效订单
            update orders set order_status='50', update_time=now() where order_status = '10' and datediff(NOW(),update_time)>=3;

    <update id="updateOrderInvalidAfter3Days" statementType="CALLABLE">
         CALL updateOrderInvalidAfter3Days
     </update>

@Autowired
    private OrdersMapper ordersMapper;
    
    @Override
    public void updateOrderInvalidAfter3Days() {
        int result = ordersMapper.updateOrderInvalidAfter3Days();
        System.out.println(result);
