使用Java连接SQLserver数据库_com.microsoft.sqlserver.jdbc.sqlserverdatasource

0、准备

使用win10、SQLServer2012、eclipse2020-6、Java1.8.0_311

1、安装微软官方的JDBC，并配置环境变量 Download Microsoft JDBC Driver 6.0 for SQL Server from Official Microsoft Download Center

 

 下载sqljdbc_6.0.8112.200_chs.tar.gz，再将其解压sqljdbc_6.0.8112.200_chs.tar

 这里x64是在适于64位，x86是适于32位，选择合适自己电脑的，这里我的是64位的计算机，选择x64文件中的文件，下如图。

将此文件sqljdbc_auth.dll复制到D:\Java\jdk1.8.0_311\bin目录下（此路径就是安装java的路径）

然后再将此文件sqljdbc42.jar复制到D:\Java\jdk1.8.0_311\jre\lib\ext和D:\Java\jre1.8.0_311\lib\ext

 然后打开高级系统设置，配置环境变量

然后如图环境变量      

CLASSPATH,在原有的基础上添加D:\Java\sqljdbc42.jar（这里是存放sqljdbc42.jar的路径，记得用" ; "来与前面的分隔。

然后找到D:\Java\jre1.8.0_311\lib\security下的java.security文件

找到下面这些并注释，并保存

 

 2、sqlserver设置

首先打开SQLserver配置管理器，选择如图下的TCP/IP，并将其启动

然后选择TCP/IP点击右键，选择属性，如图修改

 

 选择SQL Server(MSSQLSERVER)重新启动

 然后检查1433端口是否打开，在cmd里输入netstat -an|findstr 1433

 3、在eclipse中实现Java和SQLserver连接代码

 在选中的Java工程下的src，如图操作

 导入之前的sqljdbc42.jar

 然后就可以在此Java工程下写代码啦！！！
