java连接到单个类中的两个不同数据库

Question

我需要从我的代码连接到两个不同的数据库。首先是Hive数据库，另一个是Oracle。为此，我需要加载两个不同的驱动程序，一个用于Hive，另一个用于Oracle。以下是我所做的：

        Class.forName("org.apache.hive.jdbc.HiveDriver");
        System.out.println("Driver Found");
        Connection connection = DriverManager.getConnection(
                "jdbc:hive2://10.8.219.36:10000/default", "lab", "lab");
        System.out.println("Connection established");

        System.out.println("------------------");

        Class.forName("oracle.jdbc.driver.OracleDriver");
        System.out.println("Driver Found");
        Connection connection1 = DriverManager.getConnection(
                "jdbc:oracle:thin:@97.253.16.117:1521:NATTDB11",
                "CDR_LOADER", "CDR_LOADER");
        System.out.println("Connection established");

当我运行上述代码时，得到的错误是：

Driver Found
Connection established
------------------
Driver Found
java.lang.IllegalArgumentException: Bad URL format
at org.apache.hive.jdbc.Utils.parseURL(Utils.java:185)
at org.apache.hive.jdbc.HiveConnection.<init>(HiveConnection.java:84)
at org.apache.hive.jdbc.HiveDriver.connect(HiveDriver.java:104)
at java.sql.DriverManager.getConnection(Unknown Source)
at java.sql.DriverManager.getConnection(Unknown Source)
at Demo.main(Demo.java:17)

我该怎么做？提前谢谢你

Answer 1

尝试使用以下方法显式注册这两个驱动程序：

DriverManager.registerDriver (new oracle.jdbc.driver.OracleDriver());
DriverManager.registerDriver (new org.apache.hive.jdbc.HiveDriver());

然后测试这两种连接类型
