在使用redis时，会用到RedisTemplate工具，需要配置配置类，以此来连接工厂、序列化存入的键值。
这里配置了两个不同的配置类，内容大致形同，细节略有不同，可挑选使用。

Redis配置类1

具备：序列化、工厂连接、键值字符串序列化、hash键值字符串序列化

package com.data.config;

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.RedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

/**
 * @ClassDescription:
 * @Author：李白
 * @Date：2023/7/25 14:44
 */
@Configuration
public class RedisTemplateConfig {

    @Bean(name = "redisTemplate")
    public RedisTemplate redisTemplate(RedisConnectionFactory factory){
        System.out.println("redis序列化-->");
        RedisTemplate redisTemplate = new RedisTemplate();
        RedisSerializer redisSerializer = new StringRedisSerializer();
        //连接工厂
        redisTemplate.setConnectionFactory(factory);
        //键序列化
        redisTemplate.setKeySerializer(redisSerializer);
        //值序列化
        redisTemplate.setValueSerializer(redisSerializer);
        //key hashMap序列化
        redisTemplate.setHashKeySerializer(redisSerializer);
        //value hashMap序列化
        redisTemplate.setHashValueSerializer(redisSerializer);
        return redisTemplate;
    }

}

Redis配置类2

具备：序列化、工厂连接、键值序字符串列化、hash键值Json序列化

package com.data.config;

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
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;

/**
 * @ClassDescription:
 * @Author：李白
 * @Date：2023/7/25 14:44
 */
@Configuration
public class RedisTemplateConfig {
    @Bean
    @SuppressWarnings("all")
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {
        RedisTemplate<String, Object> template = new RedisTemplate<String, Object>();
        template.setConnectionFactory(factory);
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
        ObjectMapper om = new ObjectMapper();
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(om);
        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
        // key采用String的序列化方式
        template.setKeySerializer(stringRedisSerializer);
        // hash的key也采用String的序列化方式
        template.setHashKeySerializer(stringRedisSerializer);
        // value序列化方式采用jackson
        template.setValueSerializer(jackson2JsonRedisSerializer);
        // hash的value序列化方式采用jackson
        template.setHashValueSerializer(jackson2JsonRedisSerializer);
        template.afterPropertiesSet();
        return template;
    }

}
