无法使用的自定义的RedisConfig RedisTemplate序列化 是什么问题

Question

我的RedisConfig文件

package com.changyanan.config;

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.ObjectMapper.DefaultTyping;
import com.fasterxml.jackson.databind.jsontype.impl.LaissezFaireSubTypeValidator;
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.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

/**
 * @Author 常亚南

 * @Description: 方法是自定义redis的配置类，自定义序列化器
 */
@Configuration
public class RedisConfig {

    @Bean
    @SuppressWarnings("all")
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory)  {
        RedisTemplate<String, Object> template = new RedisTemplate<>();

        template.setConnectionFactory(redisConnectionFactory);
        //自定义Jackson序列化配置
        Jackson2JsonRedisSerializer jsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        objectMapper.activateDefaultTyping(LaissezFaireSubTypeValidator.instance, DefaultTyping.NON_FINAL);
        jsonRedisSerializer.setObjectMapper(objectMapper);

        //key使用String的序列化方式
        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
        template.setKeySerializer(stringRedisSerializer);
        //hash的key也是用String的序列化方式
        template.setHashKeySerializer(stringRedisSerializer);
        //value的key使用jackson的序列化方式
        template.setValueSerializer(jsonRedisSerializer);
        //hash的value也是用jackson的序列化方式
        template.setHashValueSerializer(jsonRedisSerializer);
        template.afterPropertiesSet();

        return template;

    }
}

测试类

package com.changyanan.redis02springboot;


import com.changyanan.pojo.User;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.boot.test.context.SpringBootTest;

import org.springframework.data.redis.connection.RedisConnection;
import org.springframework.data.redis.core.RedisTemplate;


@SpringBootTest
class Redis02SpringbootApplicationTests {

    @Autowired
    private RedisTemplate redisTemplate;

    @Test
    void contextLoads() {
        //操作list集合
        redisTemplate.opsForList();
        //操作字符串类似 String
        redisTemplate.opsForValue();

         //获取Redis的连接对象
        RedisConnection connection = redisTemplate.getConnectionFactory().getConnection();
        connection.flushDb();

        redisTemplate.opsForValue().set("k1","dachongming");
        System.out.println(redisTemplate.opsForValue().get("k1"));

        redisTemplate.opsForValue().set("k2","大聪明");
        System.out.println(redisTemplate.opsForValue().get("k2"));

    }


}

还式走原生的 redisTemplate 不加载自己 的 RedisConfig redisTemplate是什么问题

看样子没啥问题 包扫描那一块没有限制吧？
