请教一下为啥我的 HashOperations<String, String, Integer> 的操作结果里会有一些奇怪的字符，能够去除吗？

springboot data redis

@Configuration
public class RedisConfiguration {

    @Bean
    public LettuceConnectionFactory redisConnectionFactory() {
        return new LettuceConnectionFactory(new RedisStandaloneConfiguration("localhost", 6379));
    }

    @Bean
    public RedisTemplate<String, Object> redisTemplate(@Autowired RedisConnectionFactory factory) {
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(factory);
        return template;
    }

    @Bean
    public HashOperations<String, String, Integer> hashOperations(@Autowired RedisTemplate<String, Object> template) {
        return template.opsForHash();
    }
}

键应该是干脆利落的 message:friend:4，但是结果是 \xac\xed\x00\x05t\x00\x10message:friend:4

前面那几个东西看着可太烦了

其实你用前面一串乱码搜索就能找到很多人的回答了, 这个就是 spring data 的序列化配置问题

RedisTemplate 设置一下 key 和 vlue 的序列化方法

谢谢几位我再搜索了下改成这样基本就好了

@Bean
public RedisTemplate<String, Object> redisTemplate(@Autowired RedisConnectionFactory factory) {
RedisTemplate<String, Object> template = new RedisTemplate<>();
template.setConnectionFactory(factory);
template.setDefaultSerializer(new StringRedisSerializer());
return template;
}

就是这样的话，HashOperations 的泛型必须是 HashOperations<String, String, String>。
