\xac\xed\x00\x05t\x00\x02，在SpringBoot中操作redis时，发现key多了前面的字符串

                   在SpringBoot中操作redis时，发现key多了\xac\xed\x00\x05t\x00\x02前缀
原因：
我们注入的RedisTemplate在对Redis进行操作时，采用了
JdkSerializationRedisSerializer对数据进行序列化

        this.defaultSerializer = new JdkSerializationRedisSerializer(this.classLoader != null ? this.classLoader : this.getClass().getClassLoader());

@Nullable
private RedisSerializer<?> defaultSerializer;
@Nullable
private ClassLoader classLoader;
@Nullable
private RedisSerializer keySerializer = null;
@Nullable
private RedisSerializer valueSerializer = null;
@Nullable
private RedisSerializer hashKeySerializer = null;
@Nullable
private RedisSerializer hashValueSerializer = null;

如上代码所示，对我们的key进行了JdkSerializationRedisSerializer序列化操做，所以就导致了我们的key前面出现了\xac\xed\x00\x05t\x00\x02k1这些字符
解决办法：非常简单
将注入的RedisTemplate改为StringRedisTemplate注入即可完成

 @Autowired
    private StringRedisTemplate redisTemplate;

原理：StringRedisTemplate采用了RedisSerializer.string(）方法，将二进制数据转换为字符串

public class StringRedisTemplate extends RedisTemplate<String, String> {
    public StringRedisTemplate() {
        this.setKeySerializer(RedisSerializer.string());
        this.setValueSerializer(RedisSerializer.string());
        this.setHashKeySerializer(RedisSerializer.string());
        this.setHashValueSerializer(RedisSerializer.string());
    }
