将 springboot 应用程序与部署在 openshift 上的 cassandra 集成

Question

我已经在 openshift (OpenShift Web Console) 中部署了 cassandra 3.11 服务 通过端口转发，我将通过我的本地连接到 cassandra 服务 终端。 oc 端口转发 cassandra-0 9042:9042 cqlsh -u 卡桑德拉 -p 卡桑德拉 我想通过我的 springboot 应用程序访问 cassandra 服务。 为此，我正在使用以下属性文件。

spring.data.cassandra.contact-points=cassandra-0.cassandra-1:9042,cassandra-1.cassandra-1:9042,cassandra-2.cassandra-1:9042
#spring.data.cassandra.port=9042
spring.data.cassandra.username=cassandra
spring.data.cassandra.password=cassandra
spring.data.cassandra.cluster-name=cassandra

When I am trying to run springboot application through above property file I am getting below error 

org.springframework.beans.factory.BeanCreationException.

Answer 1

试试localhost:9042。

oc port-forward 可以将请求从本地转发到远程 pod。所以，访问localhost:9042会转发到cassandra-0:9042
