任何正文请帮助我，当我点击更新或保存用户时，hibernate sql异常代码出现，我无法找到如何解决它。
所以请帮帮我!!! //更新我已将MainBase和集成代码会话管理删除到UserDAO。
public void setText(User user) {
this.txtUsername.setText(user.getUsername());
this.txtFullname.setText(user.getFullname());
Date birthdate = user.getBirthdate();
Calendar c = Calendar.getInstance();
c.setTime(birthdate);
SimpleDateFormat ft = new SimpleDateFormat("dd-MMM-yyyy");
//get Day Month Year tu birthdate he thong
int day = c.get(Calendar.DAY_OF_MONTH);
//Month bat dau tu 0
int month = c.get(Calendar.MONTH) + 1;
int year = c.get(Calendar.YEAR);
//dinh dang ngay thang DatePicker
String pattern = "dd-MMM-yy";
dpBirthdate.setConverter(new StringConverter<LocalDate>() {
DateTimeFormatter dateFormatter = DateTimeFormatter.ofPattern(pattern);
@Override
public String toString(LocalDate date) {
if (date != null) {
return dateFormatter.format(date);
} else {
return "";
}
}
@Override
public LocalDate fromString(String string) {
if (string != null && !string.isEmpty()) {
return LocalDate.parse(string, dateFormatter);
} else {
return null;
}
}
});
this.dpBirthdate.setValue(LocalDate.of(year, month, day));
this.txtAddress.setText(user.getAddress());
this.txtEmail.setText(user.getEmail());
this.txtPhonenumber.setText(user.getPhonenumber());
this.cbxRole.setValue(user.getRole());
}
public void btUpdate(ActionEvent evt) {
User user = dao.getByUsername(this.txtUsername.getText());
getText(user);
if (this.dao.save(user)) {
clearText();
tableUser();
}
}
用户DAO
public User getByUsername(String username) {
open();
User user = null;
try {
user = (User) ss.get(User.class, username);
} catch (Exception ex) {
System.out.println("Error Get Username \n" + ex);
}
close();
return user;
}
public boolean save(User user) {
try {
ss.beginTransaction();
ss.save(user);
ss.getTransaction().commit();
return true;
} catch (Exception ex) {
System.out.println("Error Save User \n" + ex);
ss.getTransaction().rollback();
return false;
}
}
当我点击更新或添加用户此节目异常
