Redis with jHipster - Default configuration hasn't been specified

Question

im using jhipster version 7.6.0 and this is my CacheConfiguration class.

@Configuration
@EnableCaching
public class CacheConfiguration {

private GitProperties gitProperties;
private BuildProperties buildProperties;

@Bean
public javax.cache.configuration.Configuration<Object, Object> jcacheConfiguration(JHipsterProperties jHipsterProperties) {
    MutableConfiguration<Object, Object> jcacheConfig = new MutableConfiguration<>();

    URI redisUri = URI.create(jHipsterProperties.getCache().getRedis().getServer()[0]);

    Config config = new Config();
    if (jHipsterProperties.getCache().getRedis().isCluster()) {
        ClusterServersConfig clusterServersConfig = config
            .useClusterServers()
            .setMasterConnectionPoolSize(jHipsterProperties.getCache().getRedis().getConnectionPoolSize())
            .setMasterConnectionMinimumIdleSize(jHipsterProperties.getCache().getRedis().getConnectionMinimumIdleSize())
            .setSubscriptionConnectionPoolSize(jHipsterProperties.getCache().getRedis().getSubscriptionConnectionPoolSize())
            .addNodeAddress(jHipsterProperties.getCache().getRedis().getServer());

        if (redisUri.getUserInfo() != null) {
            clusterServersConfig.setPassword(redisUri.getUserInfo().substring(redisUri.getUserInfo().indexOf(':') + 1));
        }
    } else {
        SingleServerConfig singleServerConfig = config
            .useSingleServer()
            .setConnectionPoolSize(jHipsterProperties.getCache().getRedis().getConnectionPoolSize())
            .setConnectionMinimumIdleSize(jHipsterProperties.getCache().getRedis().getConnectionMinimumIdleSize())
            .setSubscriptionConnectionPoolSize(jHipsterProperties.getCache().getRedis().getSubscriptionConnectionPoolSize())
            .setAddress(jHipsterProperties.getCache().getRedis().getServer()[0]);

        if (redisUri.getUserInfo() != null) {
            singleServerConfig.setPassword(redisUri.getUserInfo().substring(redisUri.getUserInfo().indexOf(':') + 1));
        }
    }
    jcacheConfig.setStatisticsEnabled(true);
    jcacheConfig.setExpiryPolicyFactory(
        CreatedExpiryPolicy.factoryOf(new Duration(TimeUnit.SECONDS, jHipsterProperties.getCache().getRedis().getExpiration()))
    );
    return RedissonConfiguration.fromInstance(Redisson.create(config), jcacheConfig);
}

Here is dependency for redisson :

<dependency>
    <groupId>org.redisson</groupId>
    <artifactId>redisson</artifactId>
</dependency>

This is my application-dev.yml:

Everything is generated by jHipster and after installation of redis version 3.2.100, im getting this exception:

Project is compiling successfully by the way.

Thanks in advance for help!

It's seem related to Redis works. You can checkout docs: https://www.baeldung.com/hibernate-second-level-cache move to "What Is a Second-Level Cache".

First, enable bean "hibernatePropertiesCustomizer" in CacheConfiguration.java:

import org.hibernate.cache.jcache.ConfigSettings;

@Bean
public HibernatePropertiesCustomizer hibernatePropertiesCustomizer(CacheManager cm) {
    return hibernateProperties -> hibernateProperties.put(ConfigSettings.CACHE_MANAGER, cm);
}

Unfortunately, Redis in Jhipster don't initial cache for each entity model, so you must to initial cache for each model in domain package, like:

@Bean
    public JCacheManagerCustomizer cacheManagerCustomizer(javax.cache.configuration.Configuration<Object, Object> jcacheConfiguration) {
        return cm -> {
            // jhipster-needle-redis-add-entry
            createCache(cm, com.project.model.YourModel1.class.getName(), jcacheConfiguration);
            createCache(cm, com.project.model.YourModel2.class.getName(), jcacheConfiguration);
        };
    }

Please add all your Model(Entity class) using @Cache annotation.
Good luck,
