hibernate - 未找到从 JNDI 检索的 DataSource 的驱动程序

问题描述

我正在尝试使用 Jndiobject 连接到 HANA 系统

<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName" value="java:comp/env/jdbc/DefaultDB" />
</bean>

在某个地方我猜我错过了一些 maven 依赖项，因为当我连接到本地 MySQL 时它工作正常，但是当我像上面的代码一样更改数据源时，我得到了下面提到的错误。

请帮忙。

解决方案

最后通过添加 HANAROW Dialect 和下面的 bean 不要忘记打开通往 SCP 的隧道。

    class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="com.sap.db.jdbc.Driver" />
    <property name="url" value = "jdbc:sap://localhost:30015/?autocommit=false" />
    <property name="username" value="user" />
    <property name="password" value="pass" />

</bean>
