从JDBC连接到MSSQL服务器时的Windows身份验证问题

Question

尝试通过Windows身份验证从Linux机器上运行的Java应用程序连接到MS SQL服务器。连接字符串：

jdbc：sqlserver：//192.168.1.50\SQLEXPRESS：1433;DatabaseName=MyData;integratedSecurity=true;authenticationScheme=JavaKerberos

出现连接错误：

com.microsoft.sqlserver.jdbc.SQLServerException: Integrated authentication failed. ClientConnectionId:42aee675-fd0d-489e-af73-574ae5c304fa
       at com.microsoft.sqlserver.jdbc.SQLServerConnection.terminate(SQLServerConnection.java:2670) ~[mssql-jdbc-6.4.0.jre8.jar:?]

       at com.microsoft.sqlserver.jdbc.SQLServerConnection.connect(SQLServerConnection.java:1077) ~[mssql-jdbc-6.4.0.jre8.jar:?]

如何理解此错误以及如何修复它？

UPD

如果我删除 authenticationScheme=JavaKerberos，如下所示：

jdbc:sqlserver://192.168.1.50\SQLEXPRESS:1433;DatabaseName=MyData;integratedSecurity=true;

我有错误：

java.sql.SQLException: No suitable driver found for
       at java.sql.DriverManager.getConnection(DriverManager.java:689) ~[?:1.8.0_171]
       at java.sql.DriverManager.getConnection(DriverManager.java:247) ~[?:1.8.0_171]

UPD 2

保留< code > authenticationScheme = JavaKerberos 并删除< code > integrated security = true ,如下所示:

jdbc:sqlserver://192.168.1.50\SQLEXPRESS:1433;DatabaseName=MyData;authenticationScheme=JavaKerberos

给出错误:

Answer 1

在Linux机器上运行的应用程序，该计算机是否加入了Windows域？

如果不是，那么您可能需要使用SQL身份验证:

jdbc:sqlserver://192.168.1.50\SQLEXPRESS;user=MyUserName;password=*****;

否则，这个尝试没有 authenticationScheme=JavaKerberos 和指定默认端口：

jdbc:sqlserver://192.168.1.50\SQLEXPRESS;DatabaseName=MyData;integratedSecurity=true;
