使用jdbc链接sqlserver 2008出现Could not get JDBC Connection,项目可以启动,但不能访问数据库 5C

JDBC:图片说明
mybatis:图片说明

jar包没问题,可以正常连接2005的数据库,链接这个2008的就不行了,求助各位大神啊

报错代码:### The error occurred while executing a query

Cause: org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (I/O Error: Connection reset)] with root cause

检查下sql server是否启用了远程访问,防火墙是否允许1433端口,以及sql server是否使用了tcp/ip协议。

上面是逆向工程的mapper,后来我自己写了个TestMapper,还是出现同样的问题: ![图片说明](https://img-ask.csdn.net/upload/201712/28/1514454719_724728.png) 另外navicat访问数据库没问题。我想会不会是连接池配置的问题,也许那些配置可能导致这种情况??

如何用JDBC将sqlserver2008大量数据转移到oracle 11g上

sqlserver2008里有一张表,表上有3K多万行的数据要先用JDBC读取,再写入到oracle,其中sqlserver有个字段是image,我是菜鸟转换不来,在线等大神来回答,也可以把代码发我邮箱370408013@qq.com,这里提问第一次,求大虾指点,这个项目我做了快一个月了还是搞不定。。。
