Redis序列化，及LocalDateTime序列化配置

@Configuration
public class RedisConfig {

    @Bean
    public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) throws UnknownHostException {
        RedisTemplate<Object, Object> template = new RedisTemplate();
        template.setConnectionFactory(redisConnectionFactory);
        // 解决中文乱码问题
        //反序列化
        Jackson2JsonRedisSerializer jackson =new Jackson2JsonRedisSerializer<>(Object.class);
        ObjectMapper mapper = new ObjectMapper();
        mapper.activateDefaultTyping(mapper.getPolymorphicTypeValidator(), ObjectMapper.DefaultTyping.NON_FINAL);
        jackson.setObjectMapper(mapper);
        template.setKeySerializer(StringRedisSerializer.UTF_8);
        template.setValueSerializer(jackson);
        template.setHashKeySerializer(StringRedisSerializer.UTF_8);
        template.setHashValueSerializer(jackson);

        //下面代码解决LocalDateTime序列化与反序列化不一致问题
        Jackson2JsonRedisSerializer<Object> j2jrs = new Jackson2JsonRedisSerializer<>(Object.class);
        ObjectMapper om = new ObjectMapper();
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        // 解决jackson2无法反序列化LocalDateTime的问题
        om.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);
        om.registerModule(new JavaTimeModule());om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL, JsonTypeInfo.As.PROPERTY);j2jrs.setObjectMapper(om);
        // 序列化 value 时使用此序列化方法
        template.setValueSerializer(j2jrs);
        template.setHashValueSerializer(j2jrs);
        return template;
    }
