Cause: java.lang.IllegalArgumentException: Sharding value must implements Comparable

作者:互联网

在使用sharding jdbc 进行 分库分表时 插入语句 遇到如下错误

错误如下

Caused by: org.apache.ibatis.exceptions.PersistenceException: 
### Error updating database.  Cause: java.lang.IllegalArgumentException: Sharding value must implements Comparable.
### The error may exist in com/style/note/sharding/mapper/OrderGoodsMapper.java (best guess)
### The error may involve com.style.note.sharding.mapper.OrderGoodsMapper.insert-Inline
### The error occurred while setting parameters
### SQL: insert into t_order_goods(user_id,order_sn,goods_name,price,gmt_create,gmt_update) values(?,?,?,?,?,?)

代码如图

OrderGoods orderGoods = new OrderGoods();
//orderGoods.setUserId((long) i);
orderGoods.setOrderSn(order.getOrderSn());
orderGoods.setGoodsName("AAA");
orderGoods.setPrice(BigDecimal.valueOf(200));
orderGoods.setGmtCreate(instance.getTime());
orderGoods.setGmtUpdate(instance.getTime());
orderGoodsService.addOrderGoods(orderGoods);

注释的代码后面才补上 之前是没有的
因为order_goods表 根据user_id 进行分库 这个值没有设置就会出错了

总结一下这个错误的原因
