在mysql中创建的会计表

CREATE TABLE IF NOT EXISTS accountant (
    accountant_id varchar(255) NOT NULL,
    email varchar(255) NOT NULL,
    name varchar(255) NOT NULL,
    password varchar(255) NOT NULL,
    phone_number varchar(255) NOT NULL,
    ic_number varchar(255) NOT NULL,
    status int(11) NOT NULL,
    verification_code  VARCHAR(255),
    email_verified varchar(1) NOT NULL DEFAULT 'N',
    PRIMARY KEY (accountant_id) 
);
ALTER TABLE ACCOUNTANT ADD COLUMN `current_timestamp` TIMESTAMP NULL DEFAULT current_timestamp;

实体类是：

@Entity
@Table(name = "accountant")
public class Accountant {

    @Id
    @GeneratedValue(generator="system-uuid")
    @GenericGenerator(name="system-uuid", strategy = "uuid")
    @Column(name = "accountant_id", unique = true)
    private String id;

    @Column(name="email")
    private String email;

    @Column(name="name")
    private String name;

    @Column(name="password")
    private String password;

    @Column(name="phone_number")
    private String phoneNumber;

    @Column(name = "ic_number")
    private String icNumber;

    @Column(name = "status")
    private int status;

    @Column(name = "verification_code")
    private String verificationCode;

    @Column(name = "email_verified")
    private String emailVerified;

    @Column(name = "current_timestamp")
    private Timestamp currentTimeStamp;
}

服务类是：

@Service("accountantService")
public class AccountantServiceImpl implements AccountantService{

    @Autowired
    private AccountantRepository accountantRepository;

    @Override
    public Accountant saveAccountant(Accountant newAccountant, String role) {
        return accountantRepository.save(newAccountant);
    }
}

AccountantRepository类是：

@Repository("accountantRepository")
@Transactional
public interface AccountantRepository extends JpaRepository<Accountant, Long> {

    Accountant findByEmail(String email);
    Accountant findById(String id);
}

Answer 1

重命名列current_timestamp。因为current_timestamp是一个MySQL函数。

Spring JPA保存实体。 MySQLSyntaxErrorException错误
