java - 使用数据库服务自动配置在 IBM/Bluemix 上启动 java 应用程序时出错

Question

我在java上有一个应用程序，使用jpa(spring-data)，我使用cf:push在bluemix上构建，一切都好..但是当应用程序开始启动时抛出:

[INFO    ] Auto-reconfiguring beans of type javax.sql.DataSource
Failed to created cloud datasource for ubivisDB service
[INFO    ] FFDC1015I: An FFDC Incident has been created: "org.cloudfoundry.reconfiguration.org.springframework.cloud.service.ServiceConnectorCreationException: Failed to created cloud datasource for ubivisDB service com.ibm.ws.webcontainer.webapp.WebApp.notifyServletContextCreated 1341" at ffdc_15.08.28_19.03.47.0.log

当我查看服务是否通过 cf:services 绑定(bind)在应用程序上时:

 mvn -P bluemix cf:services

我认为这可能是 bluemix 更新自动配置...知道吗？ ps:以前我可以毫无问题地运行，但现在我不能......

经过几天没有任何改变，我发起了一场新的 war ......现在得到了error

当绑定(bind)公认的关系数据库服务(DB2、mysql 等)时，Liberty buildpack 会自动配置数据源。 JNDI 名称为“jdbc/”。因此，您可以使用该 JNDI 名称在代码或 JPA 配置/注释中查找数据源。阅读有关 Liberty buildpack 中此自动配置功能的更多信息:https://www.ng.bluemix.net/docs/starters/liberty/index.html#automaticconfigurationofboundservices
