问题：
Spring 4 Hibernate 4:sessionFactory为空
韦阳辉
我使用Spring 4.1.6.RELEASE Hibernate 4.3.8.Final。在Tomcat 7上配置并启动web应用程序后，我的sessionFactory==null。
你能写出我做错了什么吗？以下是我的消息来源：

这是我的DAO层。我为CRUD操作和具有特定方法的子类创建基本抽象类Abstract道。
AbstractDao.java
package org.foxresult.dao.abstraction;
import org.foxresult.dao.interfaces.GenericDao;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.criterion.Order;
import org.springframework.beans.factory.annotation.Autowired;
import java.io.Serializable;
import java.util.List;
public abstract class AbstractDao<T, PK extends Serializable> implements GenericDao<T, PK> {
@Autowired
protected SessionFactory sessionFactory;
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
public T getByPK(PK key) {
T entry = null;
Session session = null;
if (key != null)
try {
session = sessionFactory.openSession();
session.clear();
entry = (T) session.get(getClassType(), key);
} catch (Exception sql) {
sql.printStackTrace();
} finally {
closeSession(session);
}
return entry;
}
public List<T> getAll() {
List<T> result = null;
Session session = null;
try {
session = sessionFactory.openSession();
session.clear();
result = session.createCriteria(getClassType()).
addOrder(Order.asc("id")).list();
} catch (Exception e) {
e.printStackTrace();
} finally {
closeSession(session);
}
return result;
}
protected void closeSession(Session session) {
if ((session != null) && (session.isOpen())) {
session.close();
}
}
}
冬眠部道.java
package org.foxresult.dao.implementations;
import org.foxresult.dao.abstraction.AbstractDao;
import org.foxresult.dao.interfaces.DepartmentDao;
import org.foxresult.entity.Department;
@Component
public class HibernateDepartmentDao extends AbstractDao<Department, Integer> implements DepartmentDao {
public Class<Department> getClassType() {
return Department.class;
}
public Integer getPK(Department object) {
return object.getId();
}
}
希望你能帮助我。我是Spring初学者。谢谢
编辑：添加Tomcat日志。当加载webapp时，我向调用getAll方法的服务发送GET请求，并获取sessionFactory的NullPointerExeption。

编辑（2）：添加DepartmentResource.java.这是一个泽西REST服务。
package org.foxresult.resources;
import org.foxresult.dao.implementations.HibernateDaoFactory;
import org.foxresult.entity.Department;
import org.foxresult.entity.wrapper.DepartmentWrapper;
import javax.ws.rs.*;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import java.util.ArrayList;
import java.util.List;
@Path("/departments")
public class DepartmentResource {
@GET
@Produces(MediaType.APPLICATION_JSON)
public List<DepartmentWrapper> getAll() {
return wrap(HibernateDaoFactory.getDepartmentDao().getAll());
}
@GET
@Produces(MediaType.APPLICATION_JSON)
@Path("/{id}")
public DepartmentWrapper get(@PathParam("id") int id) {
return wrap(HibernateDaoFactory.getDepartmentDao().getByPK(id));
}
}

您的配置似乎是正确的。你能尝试以下步骤吗
>
在事务管理器中也添加对数据源的引用
<代码>
将HibernateDepartmentDao的注释从@Component更改为@Repository

更新我的答案：
- 网络.xml应该使用具有“Spring”功能的Jersey Servlet。
在 Web .xml中，更改
<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
To This:
<servlet-class>com.sun.jersey.spi.spring.container.servlet.SpringServlet</servlet-class>
所以，在pom中.xml添加如下内容：
<dependency>
<groupId>com.sun.jersey.contribs</groupId>
