解決Spring Boot 使用RedisTemplate 存儲鍵值出現亂碼 \xac\xed\x00\x05t\x00

 

最近使用spring-data-redis RedisTemplate 操作redis時發現存儲在redis中的key不是設置的string值，前面還多出了許多類似\xac\xed\x00\x05t\x00這種字符串，如下

127.0.0.1:6379> keys *
1) "\xac\xed\x00\x05t\x00\x04pass"
2) "\xac\xed\x00\x05t\x00\x04name"
3) "name"

 

spring-data-redis的RedisTemplate<K, V>模板類在操作redis時默認使用JdkSerializationRedisSerializer來進行序列化，如下

private boolean enableDefaultSerializer = true;
private RedisSerializer<?> defaultSerializer = new JdkSerializationRedisSerializer();
private RedisSerializer keySerializer = null;
private RedisSerializer valueSerializer = null;
private RedisSerializer hashKeySerializer = null;
private RedisSerializer hashValueSerializer = null;

解決方法：更改序列化方式

private RedisTemplate redisTemplate;
 
@Autowired(required = false)
public void setRedisTemplate(RedisTemplate redisTemplate) {
    RedisSerializer stringSerializer = new StringRedisSerializer();
    redisTemplate.setKeySerializer(stringSerializer);
    redisTemplate.setValueSerializer(stringSerializer);
    redisTemplate.setHashKeySerializer(stringSerializer);
    redisTemplate.setHashValueSerializer(stringSerializer);
    this.redisTemplate = redisTemplate;
}

 

補充：也可直接使用 StringRedisTemplate ，下附redis的緩存配置，可做參考

    private long expiration;
 
    @Bean
    CacheManager cacheManager(RedisConnectionFactory connectionFactory) {
        // 配置序列化（解決亂碼的問題）
        RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig()
                .entryTtl(Duration.ofSeconds(expiration))
                .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(jackson2JsonRedisSerialize()))
                .disableCachingNullValues();
 
        return RedisCacheManager.builder(connectionFactory).cacheDefaults(config).build();
    }
 
    @Bean
    public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory factory) {
        StringRedisTemplate template = new StringRedisTemplate(factory);
        template.setValueSerializer(jackson2JsonRedisSerialize());
        template.afterPropertiesSet();
        return template;
    }
 
    private Jackson2JsonRedisSerializer jackson2JsonRedisSerialize(){
        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);
        return jackson2JsonRedisSerializer;
    }
}
