ehcache giving error after migrating spring boot from 1.5.12 to 1.5.13

Question

I have configured spring boot 1.5.12 + ehcache and everything was working fine until I upgraded spring boot to 1.5.13

application.yml has the below entry

spring:
  cache:
    jcache:
      provider: org.ehcache.jsr107.EhcacheCachingProvider
      config: ehcache.xml

my ehcache.xml is located under resources directory

The error I am receiving is:

Caused by: java.lang.IllegalArgumentException: Cache configuration does not exist 'ServletContext resource [/ehcache.xml]'

It looks like spring boot has started searching for ehcache.xml using servletContext resolver.

p.s. I had made no change in any of source code except the spring boot upgrade to 1.5.13

Am I missing some required configuration here?

Answer 1

I had figured out the fix for this problem. We need to specify the prefix classpath: with the file name to make it work.

My application.yml would look like this now

spring:
   cache:
     jcache:
        provider: org.ehcache.jsr107.EhcacheCachingProvider
        config: classpath:ehcache.xml

Hope that helps.
