Spring cache with Redis: NullPointerException - spring

Question

When I added #Cacheable annotation to my service method and executed it, I got following error:
java.lang.ExceptionInInitializerError

My configuration bean:
#Bean
public JedisConnectionFactory jedisConnectionFactory() {
JedisConnectionFactory connectionFactory = new JedisConnectionFactory();
connectionFactory.afterPropertiesSet();
return connectionFactory;
}
#Bean
public RedisTemplate<String, MemberModel> redisTemplate() {
RedisTemplate<String, MemberModel> template = new RedisTemplate<>();
template.setConnectionFactory(this.jedisConnectionFactory);
template.afterPropertiesSet();
return template;
}
#Bean
public CacheManager cacheManager() {
RedisCacheManager redisCacheManager = new RedisCacheManager(redisTemplate);
redisCacheManager.afterPropertiesSet();
return redisCacheManager;
}
Method that needs cache:
#Override
#Transactional(readOnly = true)
#Cacheable(value = "memberCache", key = "#username")
public MemberModel findMember(String username, boolean isWired) {
MemberModel mem = memMapper.selectByUsername(username);
CheckUtils.nullCheck(mem);
return mem;
}
Everything looks like normal. I can't tell what's wrong here..

This could be due to version compatibility between jedis and spring-data.
Saw this - Spring Data Redis 1.5.0 seems to be compatible with Jedis 2.6.2
