解决redis自增问题

作者:互联网

 redisTemplate.opsForValue().increment(key);
//                    redisTemplate.opsForValue().increment(key,1);

 会报错不能正常使用

在启动类加上即可

 @Bean
    public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory factory) {
        StringRedisTemplate template = new StringRedisTemplate(factory);
        //定义key序列化方式
        //RedisSerializer<String> redisSerializer = new StringRedisSerializer();//Long类型会出现异常信息;需要我们上面的自定义key生成策略,一般没必要
        //定义value的序列化方式
        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);

        // template.setKeySerializer(redisSerializer);
        template.setValueSerializer(jackson2JsonRedisSerializer);
        template.setHashValueSerializer(jackson2JsonRedisSerializer);
        template.afterPropertiesSet();
        return template;
    }
