我想使用Hibernate從JSP插入數據到MySQL，但無法獲得會話工廠的對象。java.lang.ClassNotFoundException：org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter）
我成功創建了Hibernate util類的對象，但是在獲取數據時顯示錯誤。
雖然我在JSP頁面中輸入數據並獲取DAO層中的數據。但是在DAO層，我擴展了會話工廠類。但我無法完成任務。
（Struts Action類）
package org.sachin.action;
import java.util.List;
import org.sachin.hibernate.AdminCreate;
import org.sachin.hibernate.AdminManager;
import com.opensymphony.xwork2.ActionSupport;
public class Addad extends ActionSupport {
private AdminCreate admincreate;
private List<AdminCreate> adminList;
private Long id;
AdminManager adminmanager;
public Addad() {
AdminManager adminmanager=new AdminManager();
}
public String execute() {
return SUCCESS;
}
public String add() {
AdminManager adm=new AdminManager();
System.out.println(getadmin());
try {
adm.add(getadmin());
} catch (Exception e) {
e.printStackTrace();
}
return SUCCESS;
}
public AdminCreate getadmin() {
return admincreate;
}
public List<AdminCreate> getadminList() {
return adminList;
}
public void setadmin(AdminCreate adminCreate) {
this.admincreate = adminCreate;
}
public void setadminList(List<AdminCreate> adminList) {
this.adminList = adminList;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
}
（Hibernate工具類）
package org.sachin.hibernate;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.AnnotationConfiguration;
public class HibernateUtil {
private static final SessionFactory sessionFactory = buildSessionFactory();
private static SessionFactory buildSessionFactory() {
try {
// Create the SessionFactory from hibernate.cfg.xml
return new AnnotationConfiguration().configure()
.buildSessionFactory();
} catch (Throwable ex) {
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}
（DAO類）
package org.sachin.hibernate;
import java.util.List;
import org.hibernate.HibernateException;
import org.hibernate.classic.Session;
public class AdminManager extends HibernateUtil {
public AdminCreate add(AdminCreate admincreate) {
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
session.save(admincreate);
session.getTransaction().commit();
return admincreate;
}
public List<AdminCreate> list() {
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
List<AdminCreate> admin = null;
try {
admin = (List<AdminCreate>)session.createQuery("from admin").list();
} catch (HibernateException e) {
e.printStackTrace();
session.getTransaction().rollback();
}
session.getTransaction().commit();
return admin;
}
}
（讀取數據）

標題與主體無關。 –
同意;完全不清楚你要問什麼，或者問題是什麼。 –
我只是問，我想保存從jsp到數據庫使用hibernate獲取的數據。我嘗試使用上面的代碼。但沒有運氣。一味建議 – sachin
