#缓存配置

#Redis配置
spring.redis.database=0
spring.redis.host=192.168.205.100

dao

@Repository
public class BookDao {
    @Cacheable("c1")
    public Book getBookById(Integer id) {
        System.out.println("getBookById");
        Book book = new Book();
        book.setId(id);
        book.setName("三国演义");
        book.setAuthor("罗贯中");
        return book;
    }
}

项目入口类开启缓存：

@SpringBootApplication
@EnableCaching
public class RediscacheApplication {
    public static void main(String[] args) {
        SpringApplication.run(RediscacheApplication.class, args);
    }
}
