我正在使用Spring 4.x和Hibernate 4.x開發基於簡單休息的CURD操作。每當我調用url來獲取數據庫中的所有用戶時，我都會遇到異常。嵌套異常是java.lang.NoSuchMethodError：org.hibernate.SessionFactory.openSession（）Lorg/hibernate/classic/Session;]
for servlet [helloApp] in context with path [/helloApp] threw exception [Request processing failed; nested exception is org.springframework.transaction.CannotCreateTransactionException: Could not open Hibernate Session for transaction; nested exception is java.lang.NoSuchMethodError: org.hibernate.SessionFactory.openSession()Lorg/hibernate/classic/Session;] with root cause

任何人都可以請清除此異常有助於代碼。我正在使用郵差進行所有其他凝乳作業。請讓我知道是否需要其他代碼。
請在下面找到控制器 - 具有會話工廠對象
package com.controller;
import java.util.List;
import java.util.Date;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

DAO類 -

}
}
請顯示代碼，而不是僅顯示錯誤_com.controller.PersonController.getAllPerson（PersonController.java）_ – Mihir
如何在_DAO_中創建_sessionFactory_對象或者在類中創建單獨的_Util_類別對象。 – Mihir
您使用的是哪種_Hibernate＆Spring？ – Mihir
