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jacksontemplate.setValueSerializer(jackson2JsonRedisSerializer);// hash的value序列化方式采用jacksontemplate.setHashValueSerializer(jackson2JsonRedisSerializer);template.afterPropertiesSet();return template;}}
