在spring boot中使用redis

第一步,引入依赖

    ```
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-redis</artifactId>
    </dependency>
    ```

第二步,配置redis

spring:
  redis:
    host: localhost
    port: 6379
    password: root
    database: 1

创建redis配置类

 @Configuration
@Slf4j
public class RedisConfiguration {
    @Bean
    public RedisTemplate redisTemplate(RedisConnectionFactory redisConnectionFactory){
        log.info("开始创建redis模板对象");
        RedisTemplate redisTemplate=new RedisTemplate();
        //设置redis的连接工厂对象
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        //设置redis key 的序列化器
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        return redisTemplate;
    }
}
