java - 使用 jdbc 驱动程序将 java 连接到 SQL Server

Question

我阅读了与之相关的其他主题，但没有找到解决方案，

        String jdbcUrl = "jdbc:sqlserver://;server_name=MYSERVERNAME,instancename=MAINSTANCENAME:1211;databaseName=MYDATABASENAME;user=MYUSER;password=MYPASSWORD";         
        Connection conn = DriverManager.getConnection(jdbcUrl);

        System.out.println("successfull");

结果是错误:线程“main”java.sql.SQLException中出现异常:没有找到适合jdbc的驱动程序:sqlserver://;...

在 pom thera 中是依赖项:

<dependencies>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>3.8.1</version>
            <scope>test</scope>
        </dependency>
        <!-- https://mvnrepository.com/artifact/com.microsoft.sqlserver/mssql-jdbc -->
        <dependency>
            <groupId>com.microsoft.sqlserver</groupId>
            <artifactId>mssql-jdbc</artifactId>
            <version>7.1.1.jre10-preview</version>
            <scope>test</scope>
        </dependency>

    </dependencies>

Answer 1

从此:

<dependency>
    <groupId>com.microsoft.sqlserver</groupId>
    <artifactId>mssql-jdbc</artifactId>
    <version>7.1.1.jre10-preview</version>
    <scope>test</scope>
</dependency>

删除这一行:

    <scope>test</scope>

它使 JDBC 驱动程序仅在单元测试期间可用。
