орг.зимовать.исключение.ConstraintViolationException: не удалось выполнить инструкцию
так вот в чем дело.. Я создаю веб-приложение, используя struts2 и hibernate. Я создаю страницу изменения пароля, с помощью которой пользователь может изменить свой пароль. Но я получаю ошибку как "org.hibernate.exception.ConstraintViolationException: could not execute statement".. Ниже приведен мой код и трассировка стека.

Я новичок в распорках и спячке.. Поэтому я прошу вашей помощи.. Я могу дать больше информации, если нужно.. Я пробовал большинство решений уступили так, но никто из них не помог
1 ответов
ошибка ясна, пароль (старый или новый) не установлен в вашем действии POJO. Таким образом, вы получаете NULL который, кажется, не может быть вставлен вам DB (для НЕ НУЛЕВОГО ограничения на вас DB столбец).
имя тегов паролей не соответствует имени вашего POJO, это позволяет перехватчику параметров и управляемому моделью перехватчику заполнять ваш POJO. (В противном случае, как стойки могут касаться, какое поле должно быть помещено в какое свойство)
поэтому измените теги как (сделайте это и для других тегов):
<s:password name="oldpwd" label="Old Password"/>
<s:password name="newpwd" label="New Password"/>
пожалуйста, обратитесь к:
https://struts.apache.org/docs/parameters-interceptor.html
https://struts.apache.org/docs/model-driven.html
также, пожалуйста, обратитесь к представляет ли интерфейс ModelDriven эксплот безопасности в struts2?
