我有以下问题：

我有两个应用程序 app_1 和 app_2。

  • app_1 运行 Tomcat 7 (JBoss EWS 2.0)。
  • App_2 运行共享 MySQL。

我可以通过 MySQL 命令行从 app_1 连接到 app_2 没有问题。

现在当我在Spring conf文件中输入相同的数据连接并放入app_1时，我无法连接到app_2。

我错了什么？

这是我的配置。

数据源.xml

<bean id="dataSource"
    class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="username" value="adminus7xxx" />
    <property name="password" value="xxxxx" />
    <property name="driverClassName" value="com.mysql.jdbc.Driver" />
    <property name="url" value="jdbc:mysql://525543ddd382ece1c300018b-lieferplatz.rhcloud.com:36091/<db_name>" />
</bean>

该程序在我的本地 Tomcat 上运行没有问题，当然还有本地连接数据

这是错误跟踪
