Question

我正在尝试连接到外部mySql数据库。我在控制台上收到此错误消息：

Caused by: org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Access denied for user 'adminbnnSIES'@'localhost' (using password: YES))

Caused by: org.springframework.transaction.CannotCreateTransactionException: Could not open Hibernate Session for transaction; nested exception is org.hibernate.exception.GenericJDBCException: Cannot open connection

这就是我的applicationContext.xml的样子：

    </bean>
    <!-- Detect @Transactional Annotation -->
    <tx:annotation-driven transaction-manager="transactionManager" />
</beans>

我无法在任何地方找到答案。在我的pom.xml中，我有这种依赖：

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.1.31</version>
</dependency>

在本地连接上我没有这样的问题，这是我的本地bean设置：

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
    destroy-method="close">
    <property name="driverClassName" value="com.mysql.jdbc.Driver" />
    <property name="url" value="jdbc:mysql://localhost:3306/test" />
    <property name="username" value="root" />
    <property name="password" value="" />
</bean>

Answer 1

我认为问题应该在你指定的主机上，“localhost”似乎不适合外部数据库。

此Openshift指南可能会有所帮助：
