最近使用spring-data-redis RedisTemplate 操作redis时发现存储在redis中的key不是设置的string值，前面还多出了许多类似\xac\xed\x00\x05t\x00这种字符串，如下

spring-data-redis的RedisTemplate<K, V>模板类在操作redis时默认使用JdkSerializationRedisSerializer来进行序列化，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;

解决方法：

@Resource
    public RedisTemplate<String, Object> redisTemplate;
    
    /**
     * redis序列化存储
     * @param redisTemplate
     */
    @SuppressWarnings({ "rawtypes", "unchecked" })
    @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;
    }
