Spring Ehcache configuration : java.lang.IllegalStateException: error

Question

pom.xml

ehcache.xml

<cache name="myList" 
    overflowToDisk="false"  statistics="true"
    eternal="false"
    maxElementsInMemory="10000"
    timeToIdleSeconds="0"
    timeToLiveSeconds="300"
    memoryStoreEvictionPolicy="LFU" />

Java file

     public class MyClass
  {
    
    public final Map<String, String> getDepartmentsList(String userid) {
        System.out.println("I am getting the dept");
        Map<String, String> deptMap = myService.getAuthorizedDept(userid);
        return deptMap;
    }
 }
 
@Service 
import org.springframework.cache.annotation.Cacheable;
public class Myservice
{
@Cacheable(value = "myList", keyGenerator = "cacheKeyGenerator" )
    public Map<String, String> getDepartmentsList(String userid){
    }
}

cache-service.xml cacheManager configuration. I think mine is not correct and that's why I am getting the error. I am not sure what is wrong.

The following cache-service.xml worked for me.
