JDBC连接SQL Server遇到的问题

需要使用到微软的JDBC sql server的驱动类，去官网下载jar包

使用的URL模式："jdbc:sqlserver:地址:端口//;databaseName=YourDatabaseName"

不指定端口号，那么就使用默认端口号，一般为1433，可以在Sql Server的配置管理器中查看

我的端口为1433

当我使用其他端口的时候，有以下错误：

com.microsoft.sqlserver.jdbc.SQLServerException: 通过端口 1368 连接到主机 192.168.7.9 的 TCP/IP 连接失败。错误:“Connection refused: no further information。请验证连接属性。确保 SQL Server 的实例正在主机上运行，且在此端口接受 TCP/IP 连接， 还要确保防火墙没有阻止到此端口的 TCP 连接。”。

或

使用1433时有错误：

这应该是因为使用的JDK版本和JDK8不兼容，所以在运行的命令中加上--add-modules java.se.ee

即：

java -cp sqljdbc41.jar;. --add-modules java.se.ee ScoreStatistic
