java - 找不到合适的 ServiceConnectorCreator 错误 - Spring cloud/CloudFoundry

Question

全部，

当我尝试推送到 IBM Bluemix/CloudFoundry 时，我有一个 spring boot 应用程序出现错误。

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，它是 DB2 的云版本)服务。

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 cloud 抽象，但出现了下面提到的错误。

我的期望是 spring boot/cloud 应该识别我绑定(bind)到应用程序的 test-sqldb 服务并即时创建数据源。相反，当我执行 cf push 时，我得到了下面给出的错误。

假设 spring boot/cloud 对会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，有人可以指出我错过了什么吗？

我在 spring 上下文文件中有以下配置，如 this 中所述关联。 使用云配置文件与我的本地数据源配置分开。

spring 配置 - 这被导入到我的 spring 上下文中，并且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>
            <value>TomcatDbcp</value>
            <value>BasicDbcp</value>
        </cloud:pool-data-sources>-->
    </cloud:data-source>
</beans>    

Spring Boot 应用类

@SpringBootApplication
@ImportResource("classpath:/META-INF/spring/my-jpa-beans.xml")
public class JpaTestApplication {

    public static void main(String[] args) {
       SpringApplication.run(JpaTestApplication.class, args);
    }
 }

Answer 1

看来我明白发生了什么。

this 中的答案线程提到了有关服务连接器的信息，这给了我一个提示。

SqlDb 需要 DB2DataSourceCreator，它在我使用的 spring-cloud-connectors 版本 1.1.1-release 中不可用。它支持其他如 MySQL、Postgres、Redis、MongoDB、RabbitMQ 等。

升级到 1.2.0-release，我可以通过这个错误点。 感谢你们两个试图提供帮助的人。
