How to configure the Redis SpringBoot class

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.GenericJackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

/**

@Configuration
public class RedisConfig {

    // springboot启动后，自定义容器内部的redisTemplate对象，
    @Bean
    public <T> RedisTemplate<String, T> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate<String, T> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);
		
        // 使用GenericJackson2JsonRedisSerializer序列化器，可以序列化和反序列化带泛型的数组
        GenericJackson2JsonRedisSerializer genericJackson2JsonRedisSerializer = new GenericJackson2JsonRedisSerializer();
        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();

        redisTemplate.setKeySerializer(stringRedisSerializer);
        redisTemplate.setValueSerializer(genericJackson2JsonRedisSerializer);
        redisTemplate.setHashKeySerializer(stringRedisSerializer);
        redisTemplate.setHashValueSerializer(genericJackson2JsonRedisSerializer);

        // 在设置好redisTemplate属性后，使用afterPropertiesSet()方法使得设置生效
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }
