加了@JsonInclude(JsonInclude.Include.NON_NULL)也一直报错

Answer 1

出这个问题必然你在表上加上not null约束，然后你在插入时createTime 为null导致
从你的命名来看这个字段createTime是否想让它自动产生时间？
如果是的话，我建议你在插入的时候忽略这个字段

insert into hanma_order ( orderAmount, orderNo, orderStatus, payStatus, payTime, shopId, shopName, updateTime, userAddress, userId, userName, userOpenId, userPhone) values ( ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)

也就是这样，把字段从insert语句中拿走，然后在数据库给createTime 设置一个默认值，默认值为当前系统时间，由于你忽略了这个字段，那么数据库会默认以默认值给这个字段赋值，但是如果你包含了这个字段，即使你设置了默认值，数据库也不会为其设置默认值。
