春季無法使用Hive加載JDBC驅動程序類[org.apache.hive.jdbc.HiveDriver]

Question

我嘗試通過我的spring應用程序連接配置單元。我已經用MYSQL服務器配置了配置單元。我使用了以下屬性來配置數據庫。

db.dialect=org.hibernate.dialect.MySQLDialect
db.driver=org.apache.hive.jdbc.HiveDriver
db.url=jdbc:hive2://localhost:10000/MY_DATABASE
db.class=org.apache.hive.jdbc.HiveDriver
db.user=hadoop
db.password=hadoop

這是我在db.properties文件中使用的。但是運行該應用程序時，出現以下異常。

PropertyAccessException 1: org.springframework.beans.MethodInvocationException: Property 'driverClassName' threw exception; nested exception is java.lang.IllegalStateException: Could not load JDBC driver class [org.apache.hive.jdbc.HiveDriver]

    at org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:291)
    at org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:193)

在pom.xml中，我添加了以下依賴項

            <dependency>
              <groupId>org.apache.hive</groupId>
              <artifactId>hive-jdbc</artifactId>
              <version>2.1.1</version>
            </dependency>

Answer 1

您使用了錯誤的驅動程序類名稱，因此也出現了錯誤。 您需要更換它

db.driver=org.apache.hive.jdbc.HiveDriver

同

db.driver=org.apache.hadoop.hive.jdbc.HiveDriver

您可以在這里參考驅動程序文檔，以防萬一。

希望這能解決您的問題！
