How to solve the garbled code of @ Cacheable cache value?
RedisTemplate has been configured
@Bean
public RedisTemplate redisTemplateInit() {
//Key
redisTemplate.setKeySerializer(new StringRedisSerializer());
//Value
redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer());
return redisTemplate;
}
there is no problem setting values directly through RedisTemplate now.
but by caching data using @ Cacheable annotations on the method, key is normal and value will show some garbled code, as follows:
"xacxedx00x05tx00x1fStudent {name="test", age=22}"
is garbled in redis, and it is normal to take it directly with code
.
has anyone encountered this problem? How to solve
is it the second time to request the interface to garbled the returned data?
is still garbled when querying values in redis.
I also tested it in a small project in springboot, but it worked fine.
jpa:
show-sql: true
jackson:
default-property-inclusion: non_null
redis:
host: 192.168.1.111
port: 6379
it is normal for AOP that uses StringRedisTemplate to store token. No, I did not configure anything, but directly used the integration of springboot.
import org.springframework.data.redis.core.StringRedisTemplate;
then I added @ Cacheable to cache the product information when I asked for the list of the item.
@GetMapping("/list")
@Cacheable(cacheNames = "product",key = "1")
// @Cacheable(cacheNames = "product", key = "-sharpsellerId", condition = "-sharpsellerId.length() > 3", unless = "-sharpresult.getCode() != 0")
public ResultVO list(){
...
...
...
return ResultVOUtil.success(productVOList);
}
both the page and postman display data normally, and the console also runs out of sql (I perform two sql operations here)
sqlredis
redis
can you tell me more about your bug problem and reproduce the environment in which it happened?
