解决redis乱码问题

@Configuration
public class RedisConfig {
    // 编写自己的redistemplate类


    // redis序列化乱码问题，解决
    // 固定模板，拿来可用
    @Bean
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(redisConnectionFactory);
        // JSON序列化
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer= new Jackson2JsonRedisSerializer<Object>(Object.class);
        ObjectMapper om =new ObjectMapper();
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        om.activateDefaultTyping(LaissezFaireSubTypeValidator.instance, ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(om);
        // 序列化String
        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();

        //key采用string的序列化方式
        template.setKeySerializer(stringRedisSerializer);
        //hash的key也采用string序列化
        template.setHashKeySerializer(stringRedisSerializer);
        //value采用jackson
        template.setValueSerializer(jackson2JsonRedisSerializer);
        //hash采用jackson
        template.setHashValueSerializer(jackson2JsonRedisSerializer);
        template.afterPropertiesSet();

        return template;
    }
