Redis Desktop Manager中出现\xAC\xED\x00\x05t\x00乱码问题

问题

最近在使用Redis Tmeplate保存到Redis过程中出现了，以\xAC\xED\x00\x05t\x00\x12开头的乱码问题，具体如下图：

原因

其实就是，下面两个Redis配置注解不在主包名下面，导致Redis Template初始化设置没有生效，还有一个原因就是使用了默认的序列化方式。

@EnableCaching
@Configuration

解决

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.cache.annotation.EnableCaching;
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
     @SuppressWarnings("all")
     public RedisTemplate redisTemplate(RedisConnectionFactory factory) {
         RedisTemplate template = new RedisTemplate();
         template.setConnectionFactory(factory);
         Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
         ObjectMapper om = new ObjectMapper();
         om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
         om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
         jackson2JsonRedisSerializer.setObjectMapper(om);
         StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
         // key采用String的序列化方式
         template.setKeySerializer(stringRedisSerializer);
         // hash的key也采用String的序列化方式
         template.setHashKeySerializer(stringRedisSerializer);
         // value序列化方式采用jackson
         template.setValueSerializer(jackson2JsonRedisSerializer);
         // hash的value序列化方式采用jackson
         template.setHashValueSerializer(jackson2JsonRedisSerializer);
         template.afterPropertiesSet();
         return template;
     }
 }
