RedisTemplate设置的key，redis客户端取不到

原因：RedisTemplate 在set key时，key被序列化
解决办法1:

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.StringRedisSerializer;

@Configuration
public class RedisConfig {

    @Bean
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(factory);
        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
        template.setKeySerializer(stringRedisSerializer);
        template.setValueSerializer(stringRedisSerializer);
        template.setHashValueSerializer(stringRedisSerializer);
        template.setHashKeySerializer(stringRedisSerializer);
        return template;
    }
}

解决方法2：
直接用StringRedisTemplate操作
