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

                   在SpringBoot中操作redis時，發現key多了\xac\xed\x00\x05t\x00\x02前綴
原因：
我們注入的RedisTemplate在對Redis進行操作時，採用了
JdkSerializationRedisSerializer對數據進行序列化

        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;

如上代碼所示，對我們的key進行了JdkSerializationRedisSerializer序列化操做，所以就導致了我們的key前面出現了\xac\xed\x00\x05t\x00\x02k1這些字符
解決辦法：非常簡單
將注入的RedisTemplate改爲StringRedisTemplate注入即可完成

 @Autowired
    private StringRedisTemplate redisTemplate;

原理：StringRedisTemplate採用了RedisSerializer.string(）方法，將二進制數據轉換爲字符串

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());
    }
