谷歌电子表格有问题：授权。通过 oauth2callback 时收到的确切错误如下... 500 服务器错误。消息 - 无法获取访问令牌。
本地开发环境：
- 骡子 ESB 3.9
- JDK 1.8_161
- 谷歌电子表格连接器 1.2.4
http://localhost:3000/oauth2callback?state= some_generated_state_value &code= some_generated_code
<google-spreadsheets:config-with-oauth name="Google_Spreadsheets" consumerKey="${google.apiKey}" consumerSecret="${google.apiSecret}" doc:name="Google Spreadsheets">
<google-spreadsheets:oauth-callback-config domain="localhost" localPort="3000" remotePort="3000" path="oauth2callback"/>
</google-spreadsheets:config-with-oauth>
<flow name="authorizationAndAuthenticationFlow">
<http:listener config-ref="httpListenerConfig" path="${google.api}/oauth-authorize" allowedMethods="GET" doc:name="HTTP" >

<google-spreadsheets:authorize config-ref="Google_Spreadsheets" accessTokenUrl="https://accounts.google.com/o/oauth2/token" authorizationUrl="https://accounts.google.com/o/oauth2/auth" doc:name="Google Spreadsheets"/>
<logger message="Google has authorized the connector." level="INFO" doc:name="Logger: Log Google authorization"/>
<set-payload value="You have successfully authorized the connector" doc:name="Set Payload"/>
</flow>
确切的堆栈跟踪错误如下...

有关如何解决此问题的任何想法。我不确定这是连接器源代码问题还是 Google 可能会在 v4 中更改其 OAUTH2 API 实现的问题。无论哪种方式，堆栈跟踪似乎都与 TLS 证书问题有关。也许需要提供 google api 证书，所以关于如何注入应用程序或 JVM 使用的信任库以通过此证书问题的任何想法？
