</beans>

But now it is throwing an exception as

Unexpected exception parsing XML document from ServletContext resource [/WEB-INF/applicationFlowContext.xml]; nested exception is java.lang.NoClassDefFoundError: org.springframework.core.enums.LabeledEnum

Please help to resolve this issue.

回答1:

You can modify your pom to have this. Our project uses Spring 4 and Spring Web Flow 2.4.1 without issues. I also have Spring Security in there (you can remove it if you don't plan to use it). You can add other resources as needed. Remove any jars in your WEB-INF/lib folder and run mvn compile.
