Solution :
Make sure, following jar file included in your class path and lib folder.

spring-expression-3.1.1.RELEASE.jar

if you are using maven, make sure you have included dependency for spring-expression jar file

 

   org.springframework
   spring-expression
   ${org.springframework.version}
   

Note : Replace ${org.springframework.version} with version number.
