redis序列化

jedis重写序列化

    @Bean("redisTemplate")
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {
        // 构建序列化规则、在springboot 1.5.22.RELEASE下使用Jackson2JsonRedisSerializer存入redis的数据是一个json字符串，不带对象标识
        GenericJackson2JsonRedisSerializer genericJackson2JsonRedisSerializer = new GenericJackson2JsonRedisSerializer();

        // 配置redisTemplate
        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(factory);

        // 设置key-value 序列化规则
        redisTemplate.setDefaultSerializer(genericJackson2JsonRedisSerializer);
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }

lettuce 重写序列化

	@Bean
	public RedisTemplate<String, Object> redisTemplate(LettuceConnectionFactory lettuceConnectionFactory) {
		// 设置序列化
		Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<Object>(Object.class);
		ObjectMapper om = new ObjectMapper();
		om.setVisibility(PropertyAccessor.ALL, Visibility.ANY);
		om.enableDefaultTyping(DefaultTyping.NON_FINAL);
		jackson2JsonRedisSerializer.setObjectMapper(om);
		// 配置redisTemplate
		RedisTemplate<String, Object> redisTemplate = new RedisTemplate<String, Object>();
		redisTemplate.setConnectionFactory(lettuceConnectionFactory);
		RedisSerializer<?> stringSerializer = new StringRedisSerializer();
		redisTemplate.setKeySerializer(stringSerializer);// key序列化
		redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);// value序列化
		redisTemplate.setHashKeySerializer(stringSerializer);// Hash key序列化
		redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);// Hash value序列化
		redisTemplate.afterPropertiesSet();
		return redisTemplate;
	}
