im使用azure数据库,然后将所有必需的JAR文件添加到我的库中。这是我的代码,我不确定为什么它无法连接。请指教。
String connectionUrl =
"jdbc:sqlserver://bcs430-final-project.database.windows.net:1433;"
+ "database=OASIS ASSISTANT;"
+ "user=farmingdale@bcs430-final-project;"
+ "password=bcs430w!;"
+ "encrypt=true;"
+ "trustServerCertificate=false;"
+ "loginTimeout=30;";
String insertSql = "select * from dbo.BCS102 where crse = bcs102 ";
ResultSet resultSet = null;
try (Connection connection = DriverManager.getConnection(connectionUrl);
PreparedStatement prepsInsertProduct = connection.prepareStatement(insertSql, Statement.RETURN_GENERATED_KEYS);) {
prepsInsertProduct.execute();
// Retrieve the generated key from the insert.
resultSet = prepsInsertProduct.getGeneratedKeys();
// Print the ID of the inserted row.
while (resultSet.next()) {
System.out.println("Generated: " + resultSet.getString(1));
}
}
// Handle any errors that may have occurred.
catch (Exception e) {
e.printStackTrace();
}
这里是错误
java.sql.SQLException: No suitable driver found for jdbc:sqlserver://bcs430-final-project.database.windows.net:1433;database=OASIS ASSISTANT;user=farmingdale@bcs430-final-project;password=bcs430w!;encrypt=true;trustServerCertificate=false;loginTimeout=30;

错误表明您没有为JDBC安装合适的驱动器。
请检查是否已添加依赖项。使用以下代码将Microsoft SQL Server JDBC驱动程序添加到项目的依赖项中。
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>mssql-jdbc</artifactId>
<version>7.0.0.jre8</version>
</dependency>
有关更多详细信息,您可以参考本文档Quickstart: Use Java to connect to and query an Azure SQL database。可以按照本教程进行操作,避免出现此错误。
此外,您想通过AD身份验证连接到Azure SQL数据库,您的连接字符串应如下所示:
jdbc:sqlserver://***.database.windows.net:1433;database=Mydatabase;user={your_username_here};password={your_password_here};encrypt=true;trustServerCertificate=false;hostNameInCertificate=*.database.windows.net;loginTimeout=30;authentication=ActiveDirectoryPassword
您可以在Portal上获得AD连接字符串:
希望这会有所帮助。
