首先引入jotm和xpool包，通过maven引入
Java代码

测试如下：
Java代码
//第一个dao中注入
@Resource(name="sessionFactory1")
public void setSessionFactory(final SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
//第二个dao中注入
@Resource(name="sessionFactory2")
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory ;
}
@Test
@Transactional
public void save(){
Student student = new Student("mmmm",20,2008988L);
dao1.save(student);
dao2.save(student);
}
//第一个dao中注入
@Resource(name="sessionFactory1")
public void setSessionFactory(final SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
//第二个dao中注入
@Resource(name="sessionFactory2")
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory ;
}
@Test
@Transactional
public void save(){
Student student = new Student("mmmm",20,2008988L);
dao1.save(student);
dao2.save(student);
}
