Json序列化

@Configuration
public class RedisConfig {

  @Bean
  @SuppressWarnings("all")
  public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {
      RedisTemplate<String, Object> template = new RedisTemplate<String, Object>();
      template.setConnectionFactory(factory);
      Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
      ObjectMapper om = new ObjectMapper();
      om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
      om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
      jackson2JsonRedisSerializer.setObjectMapper(om);
      StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();

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

      return template;
  }
