Unsupported view type *.xhtml only types supported by this FlowViewResolver implementation are [.jsp] and [.jspx]

[quocbaodn94]

Hi All,
Currently,
I'm migrating the jsf, Spring MVC, and webflow 3.0.0 to springboot 3.5.5.
It is working normally on the springmvc, but the springboot jar file error.

WebFlowConfig1.java
WebMvcConfig.java

But I can't load the xhtml view.
It is not nice.
Message error:
