```java

@Configuration
public class RedisConfig {
@Bean
public RedisTemplate redisTemplate(RedisConnectionFactory redisConnectionFactory) {
RedisTemplate redisTemplate = new RedisTemplate<>();
//给redis模板先设置连接工厂，在设置序列化规则
redisTemplate.setConnectionFactory(redisConnectionFactory);
//设置序列化规则
redisTemplate.setKeySerializer(new StringRedisSerializer());
redisTemplate.setValueSerializer(genericJackson2JsonRedisSerializer());
redisTemplate.setHashKeySerializer(genericJackson2JsonRedisSerializer());
