Entity

@Entity(name = "Customer")
public class Customer {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    @Column(length = 64)
    private String name;
    @Column(length = 64)
    private String email;
    @Column(length = 64)
    private String address;
    @Column(length = 11)
    private String phone;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }
}

Controller

@RestController
public class  CustomerController {
  @Autowired
    CustomerRepository customerRepository;
    
     @RequestMapping(value = "/save",method = RequestMethod.POST)
    public void save(){
         Customer customer = new Customer();
         customer.setEmail("ggggggggg");
         customerRepository.save(customer);
     }
}

Repository层

@Repository
public interface CustomerRepository extends JpaRepository<Customer,Long> {
}

导包全为jax下
jpa底层使用Hibernate3自动建表
