Spring boot caching with redis,key have \xac\xed\x00\x05t\x00\x06

I want to use Spring cache @Cacheable to manager cache.And the real cache is redis.

my code like that:

@PostMapping("/post")@CachePut(value = "abc", key = "#key")public String putInRedis(@RequestParam String key, @RequestParam String value) {    saveInDB(key, value);    return value;}@GetMapping("/get")@Cacheable(value = "abc", key = "#key")public String queryRedis(@RequestParam String key) {    return findByKey(key);}

After I have the post request which is

localhost:8080/post?key=key&value=value

the redis server appear a weird key

127.0.0.1:6379> keys *1) "abc:\xac\xed\x00\x05t\x00\x03key"127.0.0.1:6379> GET "abc:\xac\xed\x00\x05t\x00\x03key""\xac\xed\x00\x05t\x00\x05value"

how to set @Cacheable's Serializer like StringRedisTemplate default：

public StringRedisTemplate() {    RedisSerializer<String> stringSerializer = new StringRedisSerializer();    setKeySerializer(stringSerializer);    setValueSerializer(stringSerializer);    setHashKeySerializer(stringSerializer);    setHashValueSerializer(stringSerializer);}

my application.properties:

spring.redis.host=localhostspring.redis.password=spring.redis.port=6379
