Is there any way to tell what version of Spring I have? [duplicate]

This question already has an answer here:

• Need Spring version# - only have spring.jar file 5 answers

I have inherited a Java web app that uses the Spring framework. I know that it is pretty dated but I cannot find out what version of Spring it uses. All Spring files don't have any version number so are named such as spring-core.jar. Also the date/time stamp doesn't help as that is from this year.

Is there any reliable way to determine the Spring version?
