Java使用SQLServerBulKCopy时出现的错误：对插入行执行操作失败 Unable to retrieve data from the source. 从 bcp 客户端收到一个对 colid 3 无效的列长度。
-------------------------------分割线----------------------------------
总结：Java使用SQLServerBulKCopy中遇到的坑，花了几个小时才能搞好！！！现在分享出来
第一个错误：java.sql.SQLException: 对插入行执行操作失败
此时数据库：此时主键是自增长
代码：做映射的时候
抛异常代码：

原因是可能是因为SQLServerBulKCopy没有考虑数据库的自增列
第二个错误：com.microsoft.sqlserver.jdbc.SQLServerException: Unable to retrieve data from the source.
此时数据库：此时主键是自增长，但是有ntext类型的值（text类型的不知道会不会也会报错，自己测试吧）
抛异常代码：
com.microsoft.sqlserver.jdbc.SQLServerException: Unable to retrieve data from the source.阅读源码：
【此时进入出错行看到下面代码↓↓↓】
这里获取nvarchar流，然后发现类型不一样！开始抛异常！
原因是因为数据库的列类型的原因String的值只能存在数据库类型的nvarchar类型
第三个错误：com.microsoft.sqlserver.jdbc.SQLServerException: 从 bcp 客户端收到一个对 colid 3 无效的列长度。
此时数据库：存在varchar类型

原因可能是因为数据库的列类型是varchar类型，不能接收中文字符串？？？（不确定）
解决思路：
1.数据库主键取消自增，把所有字符串的列全改为nvarchar类型
2.注释下图的一条或者改为false
3.因为id取消自增了所有需要增加id映射
4.解决！有问题可以留言(^_^)
