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
127.0.0.1:6379> keys *
“\xac\xed\x00\x05t\x00\x04pass”“\xac\xed\x00\x05t\x00\x04name”“name”
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：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;
}
补充：也可直接使用 StringRedisTemplate ，下附redis的缓存配置，可做参考

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;
}
}
