配置：

@Configuration
@EnableCaching
public class RedisConfig extends CachingConfigurerSupport{

    @Bean(name = "template")
    public RedisTemplate<String, Object> template(RedisConnectionFactory factory) {
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(factory);
        Jackson2JsonRedisSerializer<Object> jacksonSeial = new Jackson2JsonRedisSerializer<>(Object.class);
        ObjectMapper om = new ObjectMapper();
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        jacksonSeial.setObjectMapper(om);
        StringRedisSerializer stringSerial = new StringRedisSerializer();
        template.setKeySerializer(stringSerial);
        template.setValueSerializer(jacksonSeial);
        template.setHashKeySerializer(stringSerial);
        template.setHashValueSerializer(jacksonSeial);
        template.afterPropertiesSet();
        return template;
    }

}

用途：

@Autowired
    private RedisTemplate<String, Object> template;

还有这个

ValueOperations<String, Object> operations = template.opsForValue();

始终获取错误，警告堆栈跟踪为：

我只想用springbootdateredis做一些crud操作，比如template<string，object>。请帮帮我
