Redis支持

CacheManager配置

针对@Cacheable、@CacheEvict等注解进行了相应配置。

@Bean
public CacheManager cacheManager(LettuceConnectionFactory lettuceConnectionFactory) {
    RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig()
            //变双冒号为单冒号
            .computePrefixWith(name -> name + ":")
            .serializeKeysWith(RedisSerializationContext.SerializationPair.fromSerializer(new StringRedisSerializer()))
            .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(new GenericJackson2JsonRedisSerializer()))
            .disableCachingNullValues();
    return RedisCacheManager.RedisCacheManagerBuilder
            .fromConnectionFactory(lettuceConnectionFactory)
            .cacheDefaults(config)
            .transactionAware()
            .build();
}

Redis序列化配置

使用Jackson2JsonRdisSerializer代替了默认的序列化方法，让缓存数据不再展示为乱码。

@Bean
RedisTemplate<String, Object> objRedisTemplate(LettuceConnectionFactory lettuceConnectionFactory) {
    Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<>(
            Object.class);
    ObjectMapper om = new ObjectMapper();
    om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
    om.activateDefaultTyping(om.getPolymorphicTypeValidator(), ObjectMapper.DefaultTyping.NON_FINAL);
    om.setSerializationInclusion(JsonInclude.Include.NON_NULL);
    om.configure(SerializationFeature.FAIL_ON_EMPTY_BEANS, false);
    jackson2JsonRedisSerializer.setObjectMapper(om);

    RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
    redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
    redisTemplate.setDefaultSerializer(jackson2JsonRedisSerializer);
    redisTemplate.setKeySerializer(jackson2JsonRedisSerializer);
    redisTemplate.setHashKeySerializer(jackson2JsonRedisSerializer);
    redisTemplate.setEnableTransactionSupport(true);
    redisTemplate.setConnectionFactory(lettuceConnectionFactory);
    redisTemplate.afterPropertiesSet();
    return redisTemplate;
}
