# 79.3 使用Spring Data仓库

Spring Data可以为你的`@Repository`接口创建各种风格的实现。Spring Boot会为你处理所有事情，只要那些`@Repositories`接口跟你的`@EnableAutoConfiguration`类处于相同的包（或子包）。

对于很多应用来说，你需要做的就是将正确的Spring Data依赖添加到classpath下（JPA对应`spring-boot-starter-data-jpa`，Mongodb对应`spring-boot-starter-data-mongodb`），创建一些repository接口来处理`@Entity`对象。相应示例可参考[JPA样本](https://github.com/spring-projects/spring-boot/tree/v2.0.0.RELEASE/spring-boot-samples/spring-boot-sample-data-jpa)与[Mongodb样本](https://github.com/spring-projects/spring-boot/tree/v2.0.0.RELEASE/spring-boot-samples/spring-boot-sample-data-mongodb)。

Spring Boot会基于它找到的`@EnableAutoConfiguration`来尝试猜测你的`@Repository`定义的位置。想要获取更多控制，可以使用`@EnableJpaRepositories`注解（来自Spring Data JPA）。
