A arrayindexoutofboundsexception problem was encountered while learning Spring Cloud config .

Learning Reference 70037291, the demo in this blog post uses the CAMDEN.SR6 version.

I used the FINCHLEY.RC2 version when I built the project, the other configurations are the same, but each access profile will be reported arrayindexoutofboundsexception, as follows:

A review found that there was an error in calling the Lookuphttpclientbuilder method in the Httpclientconfigurablehttpconnectionfactory class.

I'm debugging after the 69th line breaks.

My URI in the config file is "Https://gitee.com/tree-cai/springCloudDemo.git", and the spec here is

When spec.substring (0, "\") occurs, the problem is not resolved at the moment of arrayindexoutofboundsexception.

So I tried to use the FINCHLEY.RC1 version to find the access OK.

The Httpclientconfigurablehttpconnectionfactory class is not available in the FINCHLEY.RC1 package.

Record it and pit my long time of Spring Cloud Config.
