如何解決在Hibernate4中使用ServletContext資源中定義的名稱'sessionFactory'創建bean的錯誤

在我的應用程序中，我在應用程序中使用Hibernate4實現多租戶實施，我在Tomcat的catalina中遇到了以下錯誤。如何解決在Hibernate4中使用ServletContext資源中定義的名稱'sessionFactory'創建bean的錯誤

Caused by: org.springframework.beans.factory.BeanCreationException: Could not autowire field: 
protected org.hibernate.SessionFactory com.boxco.blip.dao.BaseDao.sessionFactory; 
nested exception is org.springframework.beans.factory.BeanCreationException: 
Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/applicationContext-persistence.xml]: 
Invocation of init method failed; nested exception is java.lang.NullPointerException

這裏是我的應用程序-persistance.xml

MY AddressDao.java文件

package com.boxco.blip.dao; 

import com.boxco.blip.model.Address; 

public interface AddressDao { 
    public Address getAddressByAddressId(int addressId); 
}

我AddressDaoImpl.java文件

package com.boxco.blip.dao; 

import org.apache.log4j.Logger; 
import org.hibernate.Criteria; 
import org.hibernate.criterion.Restrictions; 
import org.springframework.stereotype.Component; 
import org.springframework.stereotype.Repository; 

import com.boxco.blip.model.Address; 
@Component 
@Repository(value = "addressDao") 

public class AddressDaoImpl extends BaseDao implements AddressDao { 
private static final Logger logger = Logger.getLogger(AddressDaoImpl.class); 

    @Override 
public Address getAddressByAddressId(int addressId) { 
    logger.info("Entering getAddressByAddressId()........"); 
    Address address = null; 
    Criteria criteria = getSession().createCriteria(Address.class); 
    criteria.add(Restrictions.eq("addressId", addressId)); 
    criteria.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY); 
    address = (Address)criteria.uniqueResult(); 
    logger.info("Exiting getAddressByAddressId().........."); 
    return address; 
}

}

我的基本道文件，其中i初始化SessionFactory對象：其中，增加

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="..."> 

<mvc:annotation-driven/> 

<context:component-scan base-package="com.boxco"> 
    <!-- <context:exclude-filter type="regex" expression="com.boxco.blip.dao.*" /> -->

      <value>/WEB-INF/validatorFas-rules.xml</value>

    </property> 
</bean> 

<bean id="validator" class="org.springmodules.validation.commons.DefaultBeanValidator"> 
    <property name="validatorFactory" ref="validatorFactory"/> 
</bean>

錯誤是我SessionFactory初始化，但它爲什麼沒有得到

package com.boxco.blip.dao; 

import java.sql.SQLException; 
import java.util.Iterator; 
import java.util.Map; 
import java.util.Map.Entry; 
import java.util.Set; 

import org.hibernate.Criteria; 
import org.hibernate.HibernateException; 
import org.hibernate.Session; 
import org.hibernate.SessionFactory; 
import org.hibernate.criterion.Restrictions; 
import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.beans.factory.annotation.Qualifier; 
import org.springframework.orm.hibernate3.HibernateTemplate; 

import com.mysql.jdbc.Connection; 

public abstract class BaseDao 
{ 

@Autowired 
@Qualifier("sessionFactory") 
protected SessionFactory sessionFactory; 

protected void init(SessionFactory factory) { 
    try { 
     setSessionFactory(factory); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 

} 

public SessionFactory getSessionFactory() { 
    return sessionFactory; 
} 

public void setSessionFactory(SessionFactory sessionFactory) { 
    this.sessionFactory = sessionFactory; 
} 

public Session getSession() throws HibernateException { 
    // return sessionFactory.getCurrentSession(); 
    return sessionFactory.withOptions().tenantIdentifier("BLIP1314ERP") 
      .openSession(); 
} 

    //some more methods 
    }

我的調度員-servlet.xml文件init是我的問題..？（我正在處理這個錯誤的第一次）..

任何建議讚賞。

@Dirk Lachowski我已經重申了這個鏈接，並在我的.xml文件中添加了org.springframework.orm.hibernate4.LocalSessionFactoryBean＆ –

您能告訴我們完整的NullPointerException的堆棧跟蹤？ –

它不應該是你的解決方案，無論如何@ @ repository的@component註解是無用的。要麼插入@repository（更適合異常轉換）或@component。

我解決它由4.3.4更換我的JAR文件到4.1.7（降級我的罐子）冬眠的版本，我不知道爲什麼它不與Hibernate
