配置redis的IP地址和端口號

redis:
 host: ip地址
 port: 6379

redis二進制序列化

創建一個redis的config類

@Configuration
public class RedisConfig {
    @Bean
    public RedisTemplate redisTemplate(RedisConnectionFactory redisConnectionFactory){
        //解決序列化丟失類型信息
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        objectMapper.activateDefaultTyping(LaissezFaireSubTypeValidator.instance,ObjectMapper.DefaultTyping.NON_FINAL, JsonTypeInfo.As.PROPERTY);
        //反序列化
        objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES,false);

        //使用Jackson2JsonRedisSerialize 替換默認序列化(默認采用的是JDK序列化)
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
        jackson2JsonRedisSerializer.setObjectMapper(objectMapper);


        RedisTemplate redisTemplate = new RedisTemplate();
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        redisTemplate.setKeySerializer(RedisSerializer.string());
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.setHashKeySerializer(RedisSerializer.string());
        redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.afterPropertiesSet();

        return redisTemplate;
    }
}
