使用redisTemplate存储数据,出现\xAC\xED\x00\x05t\x00

耳一文 2022-08-18 阅读 93

本文开发环境:SpringBoot+RedisTemplate

代码:

/**
* 缓存Map
*
* @param key
* @param dataMap
* @return
*/
@Override
public <T> HashOperations<String, String, T> setCacheMap(String key, Map<String, T> dataMap) {

HashOperations hashOperations = redisTemplate.opsForHash();
if (null != dataMap) {
for (Map.Entry<String, T> entry : dataMap.entrySet()) {
hashOperations.put(key, entry.getKey(), entry.getValue());
}
}
return hashOperations;
}

存到数据库,发现key,hash key/value都有\xAC\xED\x00\x05t\x00前缀。

后来添加了一个配置内,如下:

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

@Configuration
public class RedisConfig {

@Bean
public RedisTemplate redisTemplate(RedisConnectionFactory connectionFactory) {

RedisTemplate template = new RedisTemplate<>();

template.setConnectionFactory(connectionFactory);

//使用Jackson2JsonRedisSerializer来序列化和反序列化redis的value值
//
Jackson2JsonRedisSerializer serializer = new Jackson2JsonRedisSerializer(Object.class);

ObjectMapper mapper = new ObjectMapper();

mapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);

mapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);

serializer.setObjectMapper(mapper);

template.setValueSerializer(serializer);

//使用StringRedisSerializer来序列化和反序列化redis的key值

template.setKeySerializer(new StringRedisSerializer());


/*hash字符串序列化方法*/
template.setHashKeySerializer(new StringRedisSerializer());
template.setHashValueSerializer(new StringRedisSerializer());

template.afterPropertiesSet();

return template;

}

}

添加那3行代码解决问题。如果不使用json功能,注释ObjectMapper相关代码
