  使用xml配置文件加载

  对于大多数之前使用xml文件配置的同学，还想沿用xml文件配置Redis，只要在application中引入xml文件即可。

  @ImportResource(locations={"classpath:spring/spring-redis.xml"})
  @SpringBootApplication
  public class SpringBootRedisApplication {
      public static void main(String[] args) {
          SpringApplication.run(SpringBootRedisApplication.class, args);
      }
  }
