在application.yml中配置Redis服務地址

創建Redis配置類

/*** Redis配置類** 該類配置了Redis的核心功能* RedisTemplate的序列化配置*/
@Configuration
@EnableCaching // 啟用Spring緩存注解支持
public class RedisConfig extends CachingConfigurerSupport
{/*** 配置RedisTemplate** @param connectionFactory Redis連接工廠* @return 配置好的RedisTemplate實例*/@Bean@SuppressWarnings(value = { "unchecked", "rawtypes" })public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory connectionFactory){// 創建RedisTemplate實例RedisTemplate<Object, Object> template = new RedisTemplate<>();// 設置連接工廠template.setConnectionFactory(connectionFactory);// 創建FastJson2序列化器，用于值(value)的序列化FastJson2JsonRedisSerializer serializer = new FastJson2JsonRedisSerializer(Object.class);// 設置鍵(key)的序列化器為StringRedisSerializer// StringRedisSerializer專門用于字符串序列化，保證key的可讀性template.setKeySerializer(new StringRedisSerializer());// 設置值(value)的序列化器為FastJson2JsonRedisSerializer// 用于復雜對象的序列化template.setValueSerializer(serializer);// 設置Hash結構的key的序列化器template.setHashKeySerializer(new StringRedisSerializer());// 設置Hash結構的value的序列化器template.setHashValueSerializer(serializer);// 初始化模板屬性template.afterPropertiesSet();return template;}}

緩存工具類
