Exceptions while running spring boot code with distributed terracotta ehcache - spring

Question

i have created a spring boot project which uses distributed ehcache. I downloaded and run terracotta server with configuration in tc-config.xml. Servers are running successfully on localhost:9510. following is my ehcache.xml which is in classpath of spring boot project
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="ehcache.xsd">
<terracottaConfig url="localhost:9510"/>
<cache name="ticketsCache" maxEntriesLocalHeap="1000">
<terracotta consistency="eventual"/>
</cache>
</ehcache>
Following is my maven dependencies.

Following is my code in which i am trying to create a cache manager so that it can be used in my application
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cache.CacheManager;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.cache.ehcache.EhCacheCacheManager;
import org.springframework.cache.ehcache.EhCacheManagerFactoryBean;
import org.springframework.context.annotation.Bean;
import org.springframework.core.io.ClassPathResource;
#SpringBootApplication
#EnableCaching
public class TicketBookingManagementApplication {
public TicketBookingManagementApplication() {
}
#Bean
public CacheManager cacheManager() {
return new EhCacheCacheManager(ehCacheCacheManager().getObject());
}
#Bean
public EhCacheManagerFactoryBean ehCacheCacheManager() {
EhCacheManagerFactoryBean cmfb = new EhCacheManagerFactoryBean();
cmfb.setConfigLocation(new ClassPathResource("ehcache.xml"));
cmfb.setShared(true);
return cmfb;
}
public static void main(String[] args) {
SpringApplication.run(TicketBookingManagementApplication.class, args);
}
}
But i am getting exceptions as below

Any help would be appreciated

Answer 1

You have mismatched versions:
Your XML and the Spring integration are relevant for Ehcache 2.x
Your Ehcache dependencies are the Ehcache 3.x coordinates
You need to pick one as Ehcache 2 and 3 are not compatible between each others.
If you want to use Ehcache 2.x, comment out the Ehcache 3 dependencies and use the Ehcache 2 ones.
If you want to use Ehcache 3.x, replace the Spring Ehcache integration by the Spring JCache integration and update the XML to use the Ehcache 3 format.

Answer 2

Use below maven dependency in your pom.xml
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
<version>4.3.4.RELEASE</version>
</dependency>
Also, make sure that you use version 4.3.4. Don't use 5.0.6 It didn't work for me.
