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上有一个使用jpa（spring-data）的应用程序，并且我在cf：push的bluemix上进行了构建，一切正常..但是当应用程序开始开始时抛出该错误：

[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

当我看到服务是否与cf：services绑定在应用程序上时：

 mvn -P bluemix cf:services

我认为可能是bluemix更新自动配置...任何想法吗？ ps：以前我可以毫无问题地运行，但是现在我不能...

经过几天没有任何变化，我发起了一场新的战争...现在出现了一个错误

当绑定了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名称将为“ jdbc /”。 因此，您可以使用该JNDI名称在代码或JPA配置/批注中查找数据源。 在Liberty buildpack中阅读有关此自动配置功能的更多信息： https ://www.ng.bluemix.net/docs/starters/liberty/index.html#automaticconfigurationofboundservices
