SpringBoot 2.1.1.RELEASE 集成JPA  
依赖:

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

编程：

/**
     * 部门对象 sys_dept
     * 
     */
    @Entity
    @Table(name="app_dept")
    public class Dept extends BaseEntity
    {
        private static final long serialVersionUID = 1L;
    
        /** 部门ID */
        @Id
        @GeneratedValue(strategy = GenerationType.IDENTITY) // 设置主键自增
        @Column(name = "dept_id")
        private Long deptId;
        /** 部门名称 */
        @Column(name = "dept_name")
        private String deptName;
    
        public Long getDeptId() {
            return deptId;
        }
    
        public void setDeptId(Long deptId) {
            this.deptId = deptId;
        }
    
        public String getDeptName() {
            return deptName;
        }
    
        public void setDeptName(String deptName) {
            this.deptName = deptName;
        }
    }
    public interface DeptRepository  extends JpaRepository<Dept, Long> {
    
    }
    public interface IDeptService {
        Dept findById(Long id);
        List<Dept> findAll();
        Dept save(Dept dept);
        void  delete(Long id);
        Page<Dept> findAll(Pageable pageable);
    }
    @Service
    public class DeptServiceImpl implements IDeptService {
    
        @Resource
        private DeptRepository deptRepository;
        @Override
        public Dept findById(Long id) {
            return deptRepository.getOne(id);
        }
    
        @Override
        public List<Dept> findAll() {
            return deptRepository.findAll();
        }
    
        @Override
        public Dept save(Dept dept) {
            return deptRepository.save(dept);
        }
    
        @Override
        public void delete(Long id) {
            deptRepository.deleteById(id);
        }
    
        @Override
        public Page<Dept> findAll(Pageable pageable) {
            return deptRepository.findAll(pageable);
        }
    
    }
    测试：
    
    @Test
    public void RepositoryTest(){
       Dept dept=new Dept();
       dept.setDeptName("研发中心");
       deptService.save(dept);
    
    }
