我无法从已部署的 bluemix 应用程序连接到我的 Compose MongoDB 服务。似乎找不到必要的证书。我原以为它会直接从环境变量 VCAP_SERVICES 中获取它。
我可以在我的本地测试环境中正常运行，因为我将 key 导入到 Java 中适当的 keystore 中。
如果我查看他们在 bluemix 上的 node.js 示例，他们实际上在连接期间传递了证书。但是，我在 Java API 上的任何地方都找不到它。
我认为我要么需要将此证书添加到 bluemix 上的 VM(似乎不太可能)，要么我需要在我不能(看不到如何)时通过 Java 驱动程序传递它。
想法？
郑重声明，这是我得到的异常:

最佳答案
记录了一些选项 here .例如:
将证书导入Java truststore文件，将文件打包到Java应用程序中，并通过JAVA_OPTS环境变量指定其路径；信任库文件可以放在资源目录下。这可用于单个应用程序:
通过使用“cf set-env”命令:
cf set-env <app> JAVA_OPTS '-Djavax.net.ssl.TrustStore=classpath:resources/config/truststore'
通过使用 manifest.yml:
---
applications:
- name: java-app
...
env:
JAVA_OPTS: '-Djavax.net.ssl.TrustStore=classpath:resources/config/truststore'
