注意：我能够运行与 jdbc 相同的查询，并且我通过工作室的测试连接显示连接成功。

Answer 1

使用下面的 driverClassName：

net.sourceforge.jtds.jdbc.Driver

数据库url:

jdbc:jtds:sqlserver://server:port/database

Answer 2

这就是我以前配置 MSSql 服务器的方式:-

 <db:generic-config name="Generic_Database_Configuration"
        url="jdbc:sqlserver://ANIRBAN-PC\SQLEXPRESS:1433;databaseName=MyDBName;user=sa;password=mypassword"
        driverClassName="com.microsoft.sqlserver.jdbc.SQLServerDriver" doc:name="Generic Database Configuration" />

然后:-

<db:select config-ref="Generic_Database_Configuration" doc:name="Database">
    <db:parameterized-query><![CDATA[select * from table1]]></db:parameterized-query>
</db:select>

并且它运行成功......

你能试试同样的吗

Answer 3

端口有问题，最终给出端口号

jdbc:sqlserver://host:49389;instance=MYINST;username=sa;password=sa.
