Sql server 在IntelliJ中为SQL SERVER 2008设置数据源时出现NullPointerException

我试图使用sqljdbc4在Intellij中为SQL SERVER 2008设置一个数据源，收到一个错误窗口，其中显示java.lang.NullPointerException

我试过的网址：

jdbc:sqlserver://localhost\.:1433;databaseName=mobitrack

jdbc:sqlserver://localhost:1433;databaseName=mobitrack

但结果是一样的

知道是什么导致了异常吗

先谢谢你

以下是异常的屏幕截图：

是的，该URL不正确。试试这个：

jdbc:sqlserver://localhost:1433;databaseName=mobitrack

第一件事：SQL Server侦听器是否已启动并侦听端口1433

打开命令shell并键入

netstat-a

。如果在端口1433上看不到

侦听

，Java将无法连接

NullPointerException

并不意味着您没有连接。我敢打赌还有别的地方出了问题

打印堆栈跟踪。它告诉您有空引用的文件和行号。在调试器中单步执行，查看是什么以及原因

我不知道JDBC驱动程序JAR是从哪里来的，但我用于SQL Server的驱动程序名为sqljdbc.JAR。尝试更新驱动程序JAR，看看是否有帮助

我可以用IntelliJ实现这一点，你也可以。

尝试127.0.0.1而不是localhost。请尝试IDEA或IDEA。你的版本很古老。另外，请检查您是否有，或者改为尝试。我更新了想法，效果很好，谢谢。顺便说一句，问题在于表格之间的关系，而旧的想法却无法识别它们。
