现象：
使用redistemplate操作redis，随后在客户端keys *查询，发现key值多了前缀，但是不影响程序读写
经查阅资料，是RedisTemplate默认序列化方式用的是JdkSerializationRedisSerializer，此时我将key序列化方式改成StringRedisSerializer，将value序列化方式改为Jackson2JsonRedisSerializer
代码如下
private RedisTemplate redisTemplate;@Autowired(required = false)public void setRedisTemplate(RedisTemplate redisTemplate) {RedisSerializer stringSerializer = new StringRedisSerializer();//序列化为StringJackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);//序列化为JsonredisTemplate.setKeySerializer(stringSerializer);redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);redisTemplate.setHashKeySerializer(stringSerializer);redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);this.redisTemplate = redisTemplate;}
修改后再操作，前缀不见了
最后附上常见的序列化方式
