1、pom.xml新添加依賴包：

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

2、在application.properties 文件中配置連接參數(shù)：

spring.datasource.url=jdbc:oracle:thin:@localhost:1521:orcl spring.datasource.username=userstudy spring.datasource.password=userstudy spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver spring.jpa.properties.hibernate.hbm2ddl.auto=update

3、創(chuàng)建實體類Teacher，由于配置了hibernate.hbm2ddl.auto，在應(yīng)用啟動的時候框架會自動去數(shù)據(jù)庫中創(chuàng)建對應(yīng)的表。

@Entity public class Teacher {@Id@GeneratedValueprivate Long id;@Column(nullable = false)private String name;
@Column(nullable = false)private Integer age;public Teacher() {}public Teacher(String name, Integer age) {this.name = name;this.age = age;} //get set 方法 }

　4、創(chuàng)建Teacher的數(shù)據(jù)訪問接口:

public interface TeacherRepository extends JpaRepository<Teacher, Long> {Teacher findByName(String name);Teacher findByNameAndAge(String name, Integer age);Teacher save(Teacher teacher); }

　5、新建Controller類：

@RestController @RequestMapping(value="/Teacher") public class TeacherController {@Autowiredprivate TeacherRepository teacherRepository;@RequestMapping(value="/findByName")public Teacher findByName(String name){Teacher teacher=teacherRepository.findByName(name);return teacher;}@RequestMapping(value="/findAll")public List<Teacher> findAll(){List<Teacher> teacher=teacherRepository.findAll();return teacher;} }

　6、啟動項目后測試：
