Struts 2, Spring и hibernate Интеграция: переменная класса класса struts 2 всегда равна нулю

Я разрабатываю веб-приложение с использованием Struts 2, Spring и hibernate.Struts 2, Spring и hibernate Интеграция: переменная класса класса struts 2 всегда равна нулю

и когда я запускаю приложение, он всегда возвращает null в переменных класса модели в классе действий.

вот фрагменты

теперь дело в том, что, когда я развернуть военный файл в Apache Tomcat и fillup СПЯ образуют нулевые значения переменной печати actionclass модели. Я не понимаю, почему.

я забыл упомянуть, вот struts.xml

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE struts PUBLIC "-//Apache software foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd">

    <constant name="struts.custom.i18n.resources" value="messages" /> 

    <package name="default" extends="struts-default"> 

    <action name="addStudentAction" class="org.Student.ActionClasses.ApplicationAction" method="addStudent" >

      <result name="input">/ApplyOnline/ApplicationForm.jsp</result> 
      <result name="failure">/ApplyOnline/ApplicationForm.jsp</result> 

     </action> 

    </package> 

</struts>

Поскольку вы экземпляр класса модели слишком поздно. Вы должны сделать это до перехватчика params. Вы можете сделать это inline или в конструкторе, но не в методе validate.

private StudentPersonalDetails spd = new StudentPersonalDetails(); 
private ContactDetails cd = new ContactDetails() ; 
private QualificationDetails qd = new QualificationDetails() ; 

public void validate() {  
     System.out.println("validate Method Called");

~~spd = new StudentPersonalDetails();~~

РЕДАКТИРОВАТЬ:

Конфигурация пружина должна быть

<bean id="ApplicationAction" class="org.Student.ActionClasses.ApplicationAction" scope="prototype"/>

Struts конфигурации

<action name="addStudentAction" class="ApplicationAction">

Я уже это сделал. Но ничего не меняется. – ARNAB2012

Какие изменения? См. Обновления. –

метод проверки класса действия, все еще дающий null в консоли для его system.out.pritln (spd.getFirstName), .... методы – ARNAB2012

Struts 2, Spring и hibernate Интеграция: переменная класса класса struts 2 всегда равна нулю
