No suitable ServiceConnectorCreator found error - Spring cloud/CloudFoundry
提问by Hari Nair
All,
全部，
I have a spring boot app that gives me an error, when I try to push to IBM Bluemix/CloudFoundry.
当我尝试推送到 IBM Bluemix/CloudFoundry 时，我有一个 Spring Boot 应用程序给我一个错误。
This is a spring boot app, using spring cloud and trying to connect to a relational db service (sqldb which is a cloud version of DB2) service.
这是一个 spring boot 应用程序，使用 spring cloud 并尝试连接到关系数据库服务（sqldb 是 DB2 的云版本）服务。
I could connect without spring cloud, where I explicitly specified the db credentials from vcap_services in my property file. However I am trying to avoid that using spring cloud abstraction, but gets the error mentioned below.
我可以在没有 spring cloud 的情况下进行连接，我在我的属性文件中明确指定了来自 vcap_services 的数据库凭据。但是我试图避免使用 spring 云抽象，但得到了下面提到的错误。
My expectation is the spring boot/cloud should identify the test-sqldb service I bound to the app and create a data source on the fly. Instead I get the error given below when I do cf push.
我的期望是 spring boot/cloud 应该识别我绑定到应用程序的 test-sqldb 服务并动态创建数据源。相反，当我执行 cf push 时，我得到了下面给出的错误。
Is it fair to assume that spring boot/cloud pair will orchestrate the data source for me as I have the db2 driver jar and attached service in environment.? If not, can some one point to me what am I missing?
假设 spring boot/cloud 对将为我编排数据源是否公平，因为我在环境中有 db2 驱动程序 jar 和附加服务。？如果没有，有人可以指出我缺少什么吗？

I have following config in spring context file as given below as mentioned in thislink. Using the cloud profile to separate from my local datasource config.
在提到下面给出我有以下的Spring上下文文件中配置该链接。使用云配置文件与我的本地数据源配置分开。
spring config- this is imported to my spring context and is in effect when I run with cloud profile
spring 配置- 这将导入到我的 spring 上下文中，并在我使用云配置文件运行时生效
<beans profile="cloud">
<cloud:data-source id="dataSourcePref" service-name="test-sqldb">
<!-- <cloud:pool-data-sources>
<value>TomcatJdbc</value>

Seems I understood what is happening.
似乎我明白发生了什么。
An answer in thisthread mentions about Service connectors that gave me a hint.
该线程中的一个答案提到了给我提示的服务连接器。
SqlDb need DB2DataSourceCreator which was not available in spring-cloud-connectors version 1.1.1-release, which I was using. It supports others like MySQL, Postgres, Redis, MongoDB, RabbitMQ, etc..
SqlDb 需要 DB2DataSourceCreator，这在我使用的 spring-cloud-connectors 1.1.1-release 版本中不可用。它支持其他如 MySQL、Postgres、Redis、MongoDB、RabbitMQ 等。
Upgraded to 1.2.0-release and I am able to pass this error point. Thanks for two of you who tried to help.
升级到 1.2.0-release，我能够通过这个错误点。感谢你们中的两个试图提供帮助的人。
