springboot整合jp

SpringBoot整合JPA的步骤如下：
1. 在POM.xml文件中添加相关依赖，包括`spring-boot-starter-data-jpa`和`mysql-connector-java`。
2. 在Dao层创建接口，一般继承`JpaRepository<T, ID>`，其中T是实体类类型，ID是表主键类型。例如：`public interface UserVoDao extends JpaRepository<UserVO, Integer>`。
3. 在`application.properties`文件中配置数据库连接信息，包括`spring.datasource.driver-class-name`、`spring.datasource.url`、`spring.datasource.username`和`spring.datasource.password`等。
4. 在主类中添加`@EnableJpaRepositories`注解来扫描Dao层接口的包，添加`@EntityScan`注解来扫描实体类的包。例如：

@SpringBootApplication(scanBasePackages = "com.feifan.controller")
@EntityScan("com.feifan.controller")
@EnableJpaRepositories(basePackages = "com.feifan.controller")
public class Run {
    public static void main(String[] args) {
        SpringApplication.run(Run.class, args);
    }
}

以上是使用JPA方式整合SpringBoot和数据库的步骤。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
