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，我需要为Hive加载两个不同的驱动程序，为Oracle加载另一个驱动程序。这是我做的：

        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");

当我运行上面的代码时，这就是错误：

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。

尝试使用以下方法显式注册两个驱动程序：

<table id="tabla">
  <thead>
    <tr>
        <th>producto</th>
        <th>entry</th>
        <th>exit</th>
        <th>stock</th>

    </tr>
  </thead>
  <tbody>
<tr><td class="opening balance">10</td></tr>
    <tr>
        <td class="info">TP031</td>
        <td class="entry">4</td>
        <td class="exit">0</td>

        <td class="stock">14</td>
    </tr>
    <tr>
        <td class="info">SI0352</td>
        <td id="entry">0</td>
        <td class="exit">3</td>

        <td class="stock">11</td>
    </tr>
    <tr>
        <td class="info">MP4012</td>
        <td class="entry">0</td>
        <td class="exit">3</td>
        <td class="stock">9</td>
    </tr>
  </tbody>
</table>

然后测试两种连接类型。
