The 

java.lang.NoClassDefFoundError: Lorg/springframework/expression/spel/support/SimpleEvaluationContext;

means that you have upgraded to the latest Spring Integration, but you still stick with the previous Spring Framework version.

Or you need to rely on the transitive dependency from the Spring Integration, or upgrade Spring Framework as well.

All the reason of such a breaking change is here: https://spring.io/blog/2018/04/05/multiple-cve-reports-published-for-the-spring-framework
