各位大侠，本人在整合Spring和Hibernate4时出现了Failed to convert property value of type 'org.hibernate.internal.SessionFactoryImpl' to required type 'org.hibernate.Session' for property 'sessionFactory'问题，我的applicationContext.xml如下：
<bean id="employeeService" class="com.ssh.service.EmployeeService">
<property name="employeeDao" ref="employeeDao"></property>
</bean>
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="user" value="${jdbc.user}"></property>
<property name="password" value="${jdbc.password}"></property>
<property name="driverClass" value="${jdbc.driverClass}"></property>
<property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property>
<property name="initialPoolSize" value="${jdbc.initPoolSize}"></property>
<property name="maxPoolSize" value="${jdbc.maxPoolSize}"></property>
</bean>
<!-- <context:component-scan base-package="com.ssh.*"></context:component-scan>-->
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="configLocation" value="classpath:hibernate.cfg.xml"></property>
<property name="mappingLocations" value="classpath:com/ssh/entities/*.hbm.xml"></property>
</bean>
<!-- 配置xml声明式事务 -->
<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="get*" read-only="true"/>
<tx:method name="*"/>
</tx:attributes>
</tx:advice>
<aop:config>
<aop:pointcut expression="execution(* com.ssh.service.*.*(..))" id="txPointCut"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="txPointCut"/>
</aop:config>
Employee.java:
public class EmployeeDao {
private SessionFactory sessionFactory;
public Session getSessionFactory() {
return sessionFactory.getCurrentSession();
}
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
@SuppressWarnings("unchecked")
public List<Employee> getAll(){
String hql = "FROM Employee";
return getSessionFactory().createQuery(hql).list();
}
}
EmployeeService.java:
public class EmployeeService {
private EmployeeDao employeeDao;
public EmployeeDao getEmployeeDao() {
return employeeDao;
}
public void setEmployeeDao(EmployeeDao employeeDao) {
this.employeeDao = employeeDao;
}
public List<Employee> getAll(){
return employeeDao.getAll();
}
}
测试类SSHTest.java:
public class SSHTest {
private ApplicationContext ctx = null;
private EmployeeService employeeService;
{
ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
employeeService = (EmployeeService) ctx.getBean("employeeService");
}
@Test
public void testEmployeeService() {
System.out.println(employeeService.getAll());
}
}
异常信息如下：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'employeeDao' defined in class path resource [applicationContext.xml]: Initialization of bean failed; nested exception is org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'org.hibernate.internal.SessionFactoryImpl' to required type 'org.hibernate.Session' for property 'sessionFactory'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [org.hibernate.internal.SessionFactoryImpl] to required type [org.hibernate.Session] for property 'sessionFactory': no matching editors or conversion strategy found

应该是applicationContext.xml中 配置的
<property name="sessionFactory" ref="sessionFactory"></property>
这一步对应的sessionFactory出错了。网上的例子这样是可以的。然后我把在xml配置bean改成用自动注入注解的方式配置结果就可以，请问这是为什么啊？
