@Configuration
public class RedisConfig {
  @Bean
  public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
    RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<>();
    //给redis模板先设置连接工厂，在设置序列化规则
    redisTemplate.setConnectionFactory(redisConnectionFactory);
    //设置序列化规则
    redisTemplate.setKeySerializer(new StringRedisSerializer());
    redisTemplate.setValueSerializer(genericJackson2JsonRedisSerializer());
    redisTemplate.setHashKeySerializer(genericJackson2JsonRedisSerializer());
    redisTemplate.setHashValueSerializer(genericJackson2JsonRedisSerializer());
    redisTemplate.setDefaultSerializer(genericJackson2JsonRedisSerializer());
    return redisTemplate;
  }
  @Bean
  public Jackson2JsonRedisSerializer genericJackson2JsonRedisSerializer() {
    return new Jackson2JsonRedisSerializer(Object.class);
  }
}
