redis prefix redis prefix前缀

直接上源码：

@Slf4j
@Order
@Configuration
public class PreKeyRedisConfig {
    public static final String DEFUAL_PREFIX = "XXX##";
    @Autowired
    private StringRedisTemplate stringRedisTemplate;
    @Autowired
    private RedisTemplate redisTemplate;

    class PrefixRedisSerializer extends StringRedisSerializer {
        @Override
        public byte[] serialize(String s) {
            if (s == null) {
                return null;
            }
            // 这里加上你需要加上的key前缀
            String realKey = DEFUAL_PREFIX + s;
            return super.serialize(realKey);
        }
        @Override
        public String deserialize(byte[] bytes) {
            String s = bytes == null ? null : new String(bytes);
            int index = s.indexOf(DEFUAL_PREFIX);
            if (index != -1) {
                return s.substring(index + 2);
            }
            return s;
        }
    }

    @Bean
    public StringRedisSerializer stringRedisSerializer() {
        StringRedisSerializer serializer = new PrefixRedisSerializer();
        redisTemplate.setKeySerializer(serializer);
        redisTemplate.afterPropertiesSet();
        stringRedisTemplate.setKeySerializer(serializer);
        stringRedisTemplate.afterPropertiesSet();
        return serializer;
    }
}
