一、問題發現
專案中需要將部分資源存入redis中，資料型別為hash型別，程式碼使用的redisTemple。

Map map = new HashMap<String,Object>();
map.put("2021-03-12","100");
redisUtil.hashMultiSet("testHash",map);

redisUtil中的程式碼為

    public void hashMultiSet(final String key, Map<?, ?> map) {
        HashOperations<
 
String, Object, Object> hash = redisTemplate.opsForHash();
        hash.putAll(key, map);
    }

執行結果為

通過redis視覺化工具可以檢視到，所有的key和value還有hashkey和hashvalue的原始字元前，都加了一串字元。查了一下，這是JdkSerializationRedisSerializer進行序列化時，加上去的。
二、問題解決
通過查詢瞭解到現在可用的RedisSerializer主要有幾種：

（1）StringRedisSerializer

（2）Jackson2JsonRedisSerializer

（3）JdkSerializationRedisSerializer

（4）GenericToStringSerializer

（5）OxmSerializer
本次使用StringRedisSerializer來序列化和反序列化redis的key值，使用Jackson2JsonRedisSerializer來序列化和反序列化redis的value值（預設使用JDK的序列化方式）

package com.chinaunicom.utils;

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.
 
jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.autoconfigure.condition.ConditionalOnBean;
import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;
import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty;
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.RedisOperations;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

/**
 * 建立自定義redisTemplate
/
@Configuration
@ConditionalOnProperty(name = "jedis", havingValue = "true")
@ConditionalOnClass(RedisOperations.class)
public class RedisAutoConfig {

	private static Logger logger = LoggerFactory.getLogger(RedisAutoConfig.class);

	/**
	 * 自定義redisTemplate，修改序列化方式
	 */
	@Bean
	public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
		RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<>();
		redisTemplate.setConnectionFactory(redisConnectionFactory);

		// 使用Jackson2JsonRedisSerializer來序列化和反序列化redis的value值（預設使用JDK的序列化方式）
		Jackson2JsonRedisSerializer serializer = new Jackson2JsonRedisSerializer(Object.class);
		ObjectMapper mapper = new ObjectMapper();
		mapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
		mapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
		serializer.setObjectMapper(mapper);

		redisTemplate.setValueSerializer(serializer);
		redisTemplate.setHashValueSerializer(serializer);
		// 使用StringRedisSerializer來序列化和反序列化redis的key值
		redisTemplate.setKeySerializer(new StringRedisSerializer());
		redisTemplate.setHashKeySerializer(new StringRedisSerializer());

		redisTemplate.afterPropertiesSet();

		logger.info("Custom RedisTemplate success.");
		return redisTemplate;
	}

	@Bean
	@ConditionalOnBean(name = "redisTemplate")
	public RedisUtil redisUtils(RedisTemplate redisTemplate) {
		RedisUtil redisUtils = new RedisUtil();
		redisUtils.setRedisTemplate(redisTemplate);
		return redisUtils;
	}

}

配置類加上，完美解決當前問題
