这是我的GenericDaoImpl.java类
package dao;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.stereotype.Repository;
import org.springframework.stereotype.Service;
@Repository
public class GenericDaoImpl<T> extends HibernateDaoSupport implements GenericDao<T> {
@Autowired
public GenericDaoImpl(SessionFactory sessionFactory){
super.setSessionFactory(sessionFactory);
}
protected void init() {
//Do Nothing
}
@Override
public void save(T t) {
// TODO Auto-generated method stub
getHibernateTemplate().save(t);
}
@Override
public void update(T t) {
// TODO Auto-generated method stub
getHibernateTemplate().update(t);
}
@Override
public void delete(T t) {
// TODO Auto-generated method stub
getHibernateTemplate().delete(t);
}
}
以下是我的springcongif.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-2.5.xsd">
<context:component-scan base-package="controllers,dao" />
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver" >
<property name="prefix">
<value>/WEB-INF/pages/</value>
</property>
<property name="suffix">
<value>.jsp</value>
</property>
</bean>
</beans>
以下是我的hibernate.cfg.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory name="SpringConfig">
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.password">..</property>
<property name="hibernate.connection.url">..</property>
<property name="hibernate.connection.username">..</property>
<property name="hibernate.default_schema">..</property>
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<mapping class="beans.SampleBean"/>
<mapping class="beans.User"/>
</session-factory>
</hibernate-configuration>
请有人指出我,我在做错了.任何帮助将不胜感激.
解决方法:
错误是不言自明的：没有定义SessionFactory类型的Spring bean.实际上,springcongif.xml中没有定义SessionFactory类型的bean.
阅读http://static.springsource.org/spring/docs/3.2.x/spring-framework-reference/htmlsingle/#orm-hibernate以了解如何定义SessionFactory类型的bean.
