我想使用Spring cache @Cacheable来管理器缓存。真正的缓存是redis。

我的代码是这样的：

@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);
}

在我有职位要求后

本地主机：8080 / post？key = key＆value = value

Redis服务器出现一个奇怪的密钥

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"

spring缓存

如何设置@Cacheable的StringRedisTemplate之类的序列化器默认值：

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

我的application.properties：

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