Solución:
intente seguir el código, me funciona en spring-boot 2.1.0.RELEASE
@Bean
public RedisCacheManager redisCacheManager(LettuceConnectionFactory lettuceConnectionFactory) {
RedisCacheConfiguration redisCacheConfiguration = RedisCacheConfiguration.defaultCacheConfig()
.disableCachingNullValues()
.entryTtl(Duration.ofHours(1))
.serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(RedisSerializer.json()));
redisCacheConfiguration.usePrefix();
return RedisCacheManager.RedisCacheManagerBuilder.fromConnectionFactory(lettuceConnectionFactory)
.cacheDefaults(redisCacheConfiguration).build();
}
Ya no acepta RedisTemplate. Así que prueba esto:
@Bean
public RedisCacheManager cacheManager(RedisConnectionFactory redisConnectionFactory,
ResourceLoader resourceLoader) {
RedisCacheManager.RedisCacheManagerBuilder builder = RedisCacheManager
.builder(redisConnectionFactory)
.cacheDefaults(determineConfiguration(resourceLoader.getClassLoader()));
List<String> cacheNames = this.cacheProperties.getCacheNames();
if (!cacheNames.isEmpty()) {
builder.initialCacheNames(new LinkedHashSet<>(cacheNames));
}
return builder.build();
}
private org.springframework.data.redis.cache.RedisCacheConfiguration determineConfiguration(
ClassLoader classLoader) {
if (this.redisCacheConfiguration != null) {
return this.redisCacheConfiguration;
}
CacheProperties.Redis redisProperties = this.cacheProperties.getRedis();
RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig();
ObjectMapper mapper = new Jackson2ObjectMapperBuilder()
.modulesToInstall( new SimpleModule().addSerializer( new NullValueSerializer(null)) )
.failOnEmptyBeans( false )
.build();
mapper.enableDefaultTyping( ObjectMapper.DefaultTyping.NON_FINAL, JsonTypeInfo.As.PROPERTY);
GenericJackson2JsonRedisSerializer serializer = new GenericJackson2JsonRedisSerializer( mapper );
//get the mapper b/c they registered some internal modules
config = config.serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(serializer));;
if (redisProperties.getTimeToLive() != null) {
config = config.entryTtl(redisProperties.getTimeToLive());
}
if (redisProperties.getKeyPrefix() != null) {
config = config.prefixKeysWith(redisProperties.getKeyPrefix());
config = config.computePrefixWith(cacheName -> redisProperties.getKeyPrefix() + cacheName + "::");
}
if (!redisProperties.isCacheNullValues()) {
config = config.disableCachingNullValues();
}
if (!redisProperties.isUseKeyPrefix()) {
config = config.disableKeyPrefix();
}
return config;
}
