Question

我无法将数据保存到数据库中。我可以在日志中看到插入SQL语句，并且还将生成的ID写入日志。我面临的问题是数据没有从会话中持久存储到数据库中。从数据库中获取数据时我没有遇到任何问题。我使用的用户具有对数据库的读/写访问权限，而且我也没有收到任何错误。

我使用的是Spring 4.2.3，Hibernate 5.5.0，MySQL 5和Primefaces 5.3。

我搜索所有论坛，发现没有任何帮助我。有人遇到过类似的问题吗？

模型

@Entity
@Table(name = "borrower", uniqueConstraints = {
        @UniqueConstraint(columnNames = "borrower_id")
})
public class Borrower implements java.io.Serializable {

    private static final long serialVersionUID = 1L;
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "borrower_id", unique = true, nullable = false)
    private Integer borrowerId;
    @Column(name = "borrower_code", nullable = true, length = 20)
    private String borrowerCode;
    @Column(name = "first_name", nullable = false, length = 45)
    private String firstName;
    @Column(name = "last_name", nullable = true, length = 45)
    private String lastName;
    @Column(name = "phone", nullable = true, length = 45)
    private String phone;
    @Column(name = "borrower_status", nullable = false, length = 15)
    private String borrowerStatus;
    @Column(name = "email_id", nullable = false, length = 200)
    private String emailId;

    public Borrower() {
    }

    // Getters and setters
}

DAO

public class BorrowerDAOImpl extends HibernateDaoSupport implements BorrowerDAO {

    private final Logger logger = LogManager.getLogger(getClass());
    @Autowired
    private SessionFactory sessionFactory;

    @Override
    public boolean saveBorrower(Borrower borrower) {
        try {
            Session session = sessionFactory.getCurrentSession();
            session.persist(borrower);
            session.flush();
            logger.info("Borrower '{} {}' with Borrower ID '{}' saved successfully.", borrower.getFirstName(), borrower.getLastName(), borrower.getBorrowerId());
            session.disconnect();
            return true;
        }
        catch (Exception e) {
            logger.error("Unable to add new borrower '{} {}', error: ", borrower.getFirstName(), borrower.getLastName(), e);
            return false;
        }
    }
}

服务

@Service("borrowerBO")
@SessionScoped
@Transactional(readOnly = true)
public class BorrowerBOImpl implements BorrowerBO {

    @Autowired
    BorrowerDAO borrowerDAO;

    @Transactional(readOnly = false)
    @Override
    public boolean saveBorrower(Borrower borrower) {
        return borrowerDAO.saveBorrower(borrower);
    }

    public BorrowerDAO getBorrowerDAO() {
        return borrowerDAO;
    }

    public void setBorrowerDAO(BorrowerDAO borrowerDAO) {
        this.borrowerDAO = borrowerDAO;
    }
}
