Problem with Redisson Hibernate 2L cache config in Spring MVC

I am trying to configure Redisson Hibernate 2L cache in Spring MVC project.
I had follow tutorials, although most of them is devoted to Spring Boot.
I have added dependencies in pom.xml file:

<dependency>
  <groupId>org.redisson</groupId>
  <artifactId>redisson</artifactId>
  <version>3.12.0</version>
</dependency>
<dependency>
  <groupId>org.redisson</groupId>
  <artifactId>redisson-hibernate-53</artifactId>
  <version>3.11.6</version>
</dependency>

In persistance.xml (second level cache is set to false for now, because I only try to make it start the application):

<property name="hibernate.cache.region.factory_class" value="org.redisson.hibernate.RedissonRegionFactory"/>
  <property name="hibernate.cache.use_second_level_cache" value="false"/>
  <property name="hibernate.cache.use_query_cache" value="false"/>

And in my Configuration file:

    @Bean(destroyMethod="shutdown")
  RedissonClient redisson() {
    Config config = new Config();
    config.useClusterServers()
            .addNodeAddress("redis://127.0.0.1:6379");
    return Redisson.create(config);
  }

  @Bean
  CacheManager cacheManager(RedissonClient redissonClient) throws IOException {
    Map<String, CacheConfig> config = new HashMap<>();
    config.put("testMap",
            new CacheConfig(120000, 180000)); //2min TTL and 3min max idle time
    return new RedissonSpringCacheManager(redissonClient, config);
  }

Project is building correctly, but when I try to run it, I recieve an error:

I do not know what I’m missing in order to locate Redisson configuration..?
I would appreciate any help!

    You forgot to define path to Redisson config:

    <property name="hibernate.cache.redisson.config" value="/redisson.yaml" />

    To initialize a RedissionClient in Java code you need to create a CustomRegionFactory extending RedissonRegionFactory, then override the method createRedissonClient to create your RedissonClient like this:

    final Config redissonConfig = new Config();
       redissonConfig.useSingleServer()
               .setKeepAlive(true)
               .setConnectTimeout(1000*3)
               .setRetryAttempts(5)
               .setDnsMonitoringInterval(1000*8)
               .setAddress("redis://127.0.0.1:6379");
       return Redisson.create(redissonConfig);

    Then you need to specify your CustomRegionFactory for hibernate.cache.region.factory_class

    Hope that helps!
